Superstructure Preliminary Design Report

Superstructure Preliminary Design Report Two superstructure design options for the warehouse have been considered and discussed for the chosen layout, for the first design which is a portal frame and the other is a trusses structure. And all the materials were used in steelwork which are in S355. Design option one For this design option, simple portal frame are used as the main structural design and the frame contains 10 bays, each of them are 6m wide and 17m total length. This give a total area of 102m2 per bay which is satisfy the minimum requirement of the bay area of 85m2 at the beginning of the design brief. The height of the top of the column is 6m and the highest point of the roof is 6.9m which is using 6 degrees for designing the portal frame and which is satisfies the minimum floor to ceiling height of 6m at the beginning of the design brief as well. For the Section sizing, Loading calculations have been completed, and a size for each member has been chosen based on the loads acting on the structure. For the rafter, all secondary beams, (this includes the beams between columns, and the ridge beam), a section size of 356x171x45 UKB has been chosen. It has been assumed that the columns are unrestrained; this choice may be revised in the future. Under this assumption, along with the loading conditions, a section size of 533x210x22 UKB has been chosen for each column. Moreover, the diagonal cross spacing was used for the bracing design in order to maintain the stability of the whole structure under the wind loading and has been sized by using the load calculation conditions, a section size of 60x60x8 UKA has been chosen for all bracing on the roof. Furthermore, haunches with 10% of the span of the rafter long which to touch between each column and the corner of the rafter which mainly use to obtain the effect of hogging. Advantages: The main braces of the structure located on the roof of the portal frame that gives more cavity in between columns. In other words, it gives more options for the locations of the gates for the lorries to drop off. On the other hand, more fire exit can be set. As the roof make angles with both front and side of the structure, the brace on the roof can undertake wind pressure in both directions. In which, less brace is held in front and side of it. This cost less time and cost to construct. The whole structure is design to make with steel beams. This gives the structure with higher strength compare with concrete beams and columns. Between columns and columns, they have equal spaces. This led them to share the same amount to compression. The columns will share the same displacement during deformation. Easier approximation while the structure collapses. As each portal frame share the same structure, it spends less time to construct. Pin joints are used as the support on the bottom of each columns instead of fixed support, the columns of the structure undergo lesser banding moments. A vertical brace is held on the last part of the structure, it supports the brace on the roof. In other words, the materials use to make brace on the roof can be reduced. Two extra columns have been placed at both ends of the portal frame in order to support the end-span, as both end-spans do not have secondary beams either side to help stabilise the rafters in these sections. Disadvantages: While the main braces are on the top of the roof, the columns have to support higher load. The only vertical brace may block the space in between the columns. The main entrance may have to move. Design option two The second design option utilises a Pratt-pattern truss between the columns of each bay to replace a rafter with a haunch. Same as the first design, the frame contains 8 bays, each 6m wide and with a total length of 17m; giving a total area of 102m2 per bay which is satisfy the minimum requirement of the bay area of 85m2 at the beginning of the design brief. The height of the top of the column is 6m and the highest point of the roof is 6.9m which is using 6 degrees for designing the portal frame and which is satisfies the minimum floor to ceiling height of 6m at the beginning of the design brief as well. This design has no bracing as the truss can be afford for the lateral load to maintain the stability of the structure, attained from the use of a truss is sufficient enough to invalidate the use of bracing elsewhere in this particular design. Two extra columns have been placed at both end trusses in order to support the end-span, as both end-spans do not have secondary beams at either side of the truss to help stabilise them. The struts in the trusses are to be connected to the tie beam and rafter using gusset plates and bolts; and the bracing attached to the rafters using the same method. For the Section sizing, Loading calculations have been completed, and a size for each member has been chosen based on the loads acting on the structure. For the rafter, all secondary beams, (this includes the beams between columns, and the ridge beam), a section size of 356x171x45 UKB has been chosen. It has been assumed that the columns are unrestrained; this choice may be revised in the future. Under this assumption, along with the loading conditions, a section size of 533x210x22 UKB has been chosen for each column. Advantages The design has large amount of trusses set on top of the structure. It can from the side of the structure. The whole structure is design to make with steel beams. This gives the structure with higher strength compare with concrete beams and columns. As no vertical brace with the structure to the bottom, this allow extra lorry loading gates. Other than that, flexible fire exits can be set. Equal spacing within columns and columns, this lead to share the same amount to compression. The columns will share the same displacement during deformation. Easier approximation while the structure collapses. Pin joints are used as the support on the bottom of each columns instead of fixed support, the columns of the structure undergo lesser banding moments. Disadvantages As the trusses held on the top of the structure, it gives extra load on the column. Thicker columns have to be used. The cost is relatively high due to the following reasons: -Lot of connections with that trusses -More materials are used -More complied structure, harder to construct While space on the upper part uses as trusses, lesser goods can be stored, it may decrease the efficiency of the portal frame. Construction is time consuming as it has complicated structure.

Comparing and contrasting lease versus purchase options Essay

It is important to know the difference between lease purchase and lease option. The use of leases can also have an impact on a company’s liquidity profitability ratios (Schroeder, Clark, & Cathey, 2005). First the organization should study the expenses of what it would cost to lease as to what it cost to purchase this can be done with a reduced cash flow evaluation. The study would compare the expense of the alternatives by taking into account the scheduling of payments, tax benefits, and interest rates on any loans, and other financial arrangements. To make an evaluation, the company has to be sure about the financially viable lifespan of equipment, this would also include the salvage value and depreciation of such equipment. Here is a brief description of what debt financing is referred as. Debt financing is when money is borrowed by an organization and has to be repaid back with interest. Debt financing does dilute the ownership of the company. Debt financing can be looked at as either a long-term debt or short-term debt. Two examples of debt financing are the issue of Bonds and a Line of Credit. Line of Credit is a bank loan where a company can draw out funds when times are slow, and money is needed. Bonds can be issued as form of debt financing. Bonds are usually long-term and come with a maturity ranging from seven to 30 years. These bonds are usually underwritten by a bank or securities firm who assist in the sales of these bonds. Equity financing is another method of raising money by selling company stock to outside investors. In return for their interest in buying stock, the shareholder receives ownership interest in the company. An advantage to using debt is that the debt helps to produce and hold greater investment returns for the company’s equity holders. When using debt financing the primary advantage is that it allows the founders to hold ownership and control of the company. The disadvantage to this is that it  requires smaller business to make monthly payments of both principal and interest. The use of capital structure depends on what a company can afford some small companies cannot afford debt financing like larger corporations. I think equity financing is a good way for smaller companies to raise capital because the owner can still hold on to control and raise money at the same time.

The Importance Of Shareholder Wealth Maximization In Firms Finance Essay - Free Essay Example

Sample details Pages: 7 Words: 1999 Downloads: 1 Date added: 2017/06/26 Category Finance Essay Type Argumentative essay Did you like this example? My opinion is that the shareholder wealth maximization should be a superior objective over stakeholder interest because that is a common trend of firms development in a comparative market. However, in the reality companies do not just focus on the shareholders. To understand and make it clearer, we should pay attention to several definitions of shareholder, stakeholder and theories of shareholder and stakeholder and what the differences between them are, and what debates between them? First, what is shareholder? According to the web page of defining the world of investing-Investor Glossary, A  shareholder  is an individual or organization owning  stock  in a company. Shareholders have a legal claim on a percentage of the companys  earnings  and assets, and share the same level of limited liability as the company itself. In cases of bankruptcy, shareholders generally lose the entire value of their holdings. Next, w hat is stakeholder? According to Business dictionary.com, it is a person, a  group, or an organization that has a direct or indirect stake in an organization because it can affect or be affected by the organizations actions, objectives and policies. Key stakeholders in a  business  organization include creditors, customers, directors, employees, government (and its agencies), owners  (shareholders),  suppliers, unions, and the  community  from which the business draws its  resources. Form the financial point view, the objective of a firm is to maximize the wealth to the shareholders. Nevertheless, nowadays people say that the wealth maximization is only focused on its shareholders. The followings below are some views supporting and not supporting to demonstrate to the things above. According to H. Jeff Smith (2003), Shareholder theory asserts that shareholder advances capital to a companys managers, who are supposed to sp end corporate funds only in ways that have been authorized by the shareholders. Furthermore, Milton Friedman (1970) is the man supporting this theory very much. He made the most well-known version of the shareholder theory in the following passage in Capitalism and Freedom: In such an economy [a free economy], there is one and only one social responsibility of business to use its resources and engage in activities designed to increase its profits so long as it stays within the rules of the gameÃÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦without deception or fraud. In his essay The Social Responsibility of Business Is To Increase Its Profits Friedman gives a somewhat different statement of the theory: In a free-enterprise, private property system, a corporate executive is an employee of the owners of the business. He has direct responsibility to his employers. That responsibility is to conduct the business in accordance to with their desires, which will generally be to make as much money as possible while conforming to the basic rules of the society, both those embodied in law and in ethical custom. One more view supporting this theory is posted by Todd Henderson (2010). He argued that while the duty to maximize shareholder value may be a useful short hand for a corporate manager to think about how to act on a day to day basis, this is not legally required or enforceable. The only constraint on board decision making is a pair of duties the duty of care and the duty of loyalty.The duty of care requires boards to be well informed and to make deliberate decisions after careful consideration of the issues. Importantly, board members are entitled to rely on experts and corporate officers for their information, can easily comply with duty of care obligations by spending shareholder money on lawyers and process, and, in any event, are routinely indemnified against damages for any breaches of this duty. The duty of loyalty self evidently requires board members to put the i nterests of the corporation ahead of their own personal interest. And, Dodge v. Ford Motor Co., (1919) supposed corporations are organized and acted for carrying on primarily profit of the stockholders. Directors are employed on behalf of owners, has responsibility to bring more profit into strongbox of employers. They are simultaneously assigned power and duty for making decision so as to reach purpose of proprietors. Different with the above mentioned views, the stakeholder theory says that corporations should be run for the benefit of all stakeholders, not just the shareholders (Thomas L. Carson -2003). Also, R. Edward Freeman (2004) is the most prominent defender of the stakeholder theory. In his paper A Stakeholder Theory of the Modern Corporation Freeman writes: Corporations shall be managed in the interests of its stakeholder, defined as employees, financiers, customers and commodities. Moreover, in an earlier paper written together with William Evan, Freeman states as follows: The corporation should be managed for the benefit of its stakeholder: its customers, suppliers, owners, employees, and local communities. The rights of these groups must be ensured, and further, the groups must participate in some sense in decisions that substantially affect their welfare. Management bears a fiduciary relationship to stakeholders and to the corporation as an abstract entity. It must act in the interests of the shareholders as their agent, and it must act in the interests of the corporation to ensure the survival of the firm, safeguarding the long-term stakes of each group. Also, according to H. Jeff Smith stakeholder theory asserts that managers have a duty to both the corporations shareholder and individuals and constituencies that contribute, either voluntarily or involuntarily, to [a companys] wealth-creating capacity and activities, and who are therefore its potential beneficiaries and/or risk bearers. Managers are agents of all stakeholders and have two responsibilities: to ensure that the ethical rights of no stakeholder are violated and to balance the legitimate interests of the stakeholders when making decisions. The objective is to balance profit maximization with the long-term ability of the corporation to remain a going concern. From the above views of the shareholder and stakeholder theory, I support the ideal shareholder wealth maximization should be a superior objective over stakeholder interest because as follows: As we know, from a modern financial perspective a firms main objective is to maximize its shareholder wealth. The wealth is shown via the market by the price of companys common stock, which is a reflection of the 3 key variables: timing of cash flows, magnitude of cash flows and the risk of the cash flows that investors expect a firm to generate over time. Normally, profit maximization after tax (ETA) is considered as the main purpose of the firm, but it is not regarded as a objective to maximize s hareholder wealth because earnings per share (EPS) will be more important than total profits.  A company can increase its total profits by making an issue of stocks and using the returns to invest in other bonds for profits.  Even maximizing profit per share, but, is not a completely suitable goal, firstly because it does not show the time factor or period of expected interest. Secondly, next mistake of maximizing EPS is that it does not take interest in the risk or uncertainty of the future return flow. So, there are several investment projects will more risky than others.  Consequently, the prospective flow of EPS would not be more ensured if these projects were undertaken.  Besides, a firm will be more or less risky to be conditional on the total of debt relevant to equity in its capital structure.  This risk is considered as financial risk and it contributes to the uncertainty of the future flow of earnings per share too.  For instance, there are two companies A and B with the same of the expected future EPS. However, the earnings flow of the company A depends significantly more uncertainty than the earnings flow of the company B, so the market price per share of the company As stock may be lower. For the mentioned-above reasons, a maximization objective of EPS may not be the same as those maximizing market price per share.  The value of a companys stock in the market shows the focal judgment of overall market participants with what the value is of the specific business.  It mentions to present and prospective EPS, the timing, duration, and risk of these returns, and any other factors relating to market price of stock. The market price is regarded as a performance index of firms progress and this let us know that how well management is running in behalf of its stockholders. In some circumstances the management goals perhaps differ from those of the firm stockholders.  In a corporation (es pecially it goes stock market) whose stock is extensively held, stockholders give a bit of their control or influence over the company operations.  When the company control is segregated from its ownership, management does not completely try their best to do jobs for the best benefits of the stockholders. They perhaps feel satisfied to run and seek a growth level accepted and concerned a lot with maintaining their own existence than with firms value maximization to its shareholders.  The top important purpose to this management may be its own survival.  Consequently, this leads to unwilling to face with reasonable risks for their fear of making a mistake, hence becoming easily seen to the suppliers of capital from outside. Then, these suppliers may give out a threat to managements existence. To exist over a long time, management has to know to behave by a way that is reasonably suitable with maximization of shareholder value. However, the objectives of the parti es are not always necessary the same.  Maximizing shareholder value, subsequently, is a consistent example for how a firm  should  act.  When management does not follow these guides, we must recognize this as a restriction and make decision for the opportunity cost. This cost is measurable only if we decide what the result would be had the firm attempted to maximize value to shareholder. The purpose of capital markets is to effectively apportion savings in an economy from last savers to last users of capital who invest in real properties. If savings are interested in the top auspicious investment chances, a reasonable economic criteria must exist that manages their flows. In general, the savings allocation in an economy happens on the foundation of expected earnings and risk. The value of a businesss stock in the market is both of these factors. Accordingly, it reflects the markets equilibration process between returns and risk. If making decisions in accordance with the probably effect upon the market value of its stock, a business will only be able to attract capital from outside when its investment chances defend the use of that capital in the whole economy. However, this does not mean management will not mention to social responsibility and stakeholders interests. Namely, Social responsibility of a firm towards shareholders is to ensure good return on investment, towards employees is fair pay and working conditions, towards suppliers is prompt payment and fair procurement process, towards customers is fair price, safe product and after sales service and towards local community is providing jobs and supporting the community development activities, supporting education, and becoming actively involved in environmental issues like clean air and water. Hence, the stakeholders interest is the interest of stakeholders said above. The stakeholder interests sometimes conflict or influence with the shareholders interests in maxim izing wealth. Furthermore, the criteria for social responsibility and stakeholders interests are not clearly specified, making formulation of an appropriate goal function difficult. Therefore, manager has to know to coordinate between the shareholder wealth maximization and its stakeholder interests with superior financial results. In conclusion, maximizing shareholder wealth is a superior objective which a business firm must obligatorily fulfill to survive. If firms do not operate with the goal of shareholder wealth maximization in mind, shareholders will have little incentive to accept the risk necessary for a business to thrive. However, this maximization of wealth is not understood to be at all costs. It will be a contented combination between shareholder and stakeholder interests with best financial results. Depending on each specific situation, each specific circumstance and each specific condition of firms, they can sort out what is the best solution for their organization . Don’t waste time!

Effects Of Alcohol On Social Behavior - 1693 Words

The presence of alcoholic beverages seems ubiquitous today, and it has been that way for thousands of years. Nowadays, it can be found at sporting events, social gatherings, with meals, and in many other environments. Alcohol is a psychoactive drug (it alters mood and potentially consciousness) and is specifically classified as a depressant. Depressant drugs slow down the nervous system and physiological functioning while promoting a relaxing, drowsy feeling. In the case of alcohol, these aforementioned effects typically arise when heavy doses of the drug are consumed. In low to moderate doses, however, the opposite happens. The alcohol has a mood-elevating effect, along with many other physical and social symptoms that are associated with it. This essay will discuss some of the effects that alcohol has on social behavior. First, the mechanism of action alcohol has on the brain will be explained, followed by paragraphs that discuss how moderate amounts of alcohol influence social beh avior, sexual behavior, and driving ability. The fundamental basis for how alcohol effects the body starts at the neuronal level. A neuron is another name for nerve cell. The human brain contains trillions of these nerve cells, which transmit information to and from each other, and subsequently to the rest of the body. Neurons have dendrites, which contain receptors that receive chemical messages from other nerve cells. These receptors are influenced by chemicals called neurotransmitters, whichShow MoreRelated Alcohol and its Effects on Social Behavior Essay examples1093 Words   |  5 PagesAlcohol and its Effects on Social Behavior The characters in Ernest Hemingway’s novel, The Garden of Eden, exhibit an interesting social behavior throughout the story in their frequent consumption of various types of alcoholic beverages.
