Steel building design - Coursework Example At the same time, the design should also ensure and provide the necessary comfort, energy-efficiency and safety to the inhabitants. To attain the fundamental building requirements, it is then necessary to integrate adequate structural resistance to building designs. The primary purpose of this is to sustain the actions (i.e. loads, imposed displacements, thermal strains) and influences resistance so that the building will remain serviceable and durable (Brettle, 2009). Meanwhile, in order to secure the structural safety of the building during its intended life, it should be designed and executed with appropriate degrees of reliability. Further, it should also be built in an economic sustainable approach in order to meet its required serviceability structure or structural element standard. Meaning it should fit for the use or function it is required whilst providing comfort and physical aesthetic. Moreover, building designs also incorporated robustness to ensure that the built environ ment is resistant to damages cause by events such as explosion, impact and consequences of human errors (Brettle, 2009). Likewise, it is also important to consider the snow loads, wind actions, thermal actions, and other accidental actions in the building designs in order to integrate appropriate building resistant techniques and strategies. The snow load capacity of the built environment is very important to determine in order to integrate in the design the characteristic values applicable for ground snow load for the site and the imposed roof snow load and shape coefficient. The EN 1991-1-3 (Annex C) of the UK Eurocode provides the snow load map which would be used to deter snow loads for building construction. Meanwhile, the Annex B of the same Eurocode also provide the benchmarks applicable for present roof shape coefficients including other information for exceptional snow drifts, multi-span pitched roofs, roofs abutting and close to taller structures, roofs with projections, o bstructions and parapets. It is also important to note the applicable wind actions in building designs. The EN 1991-1-4 of the UK Eurocode served as guideline in order to determine the natural wind actions during the construction phase of the building. The code also included other information such values of wind actions, value of the basic wind velocity, wind speed, peak velocity pressure, and wind pressures and forces. Likewise, thermal actions should also be considered in the design in order to address the seasonal climatic changes. The characteristic values of thermal action are enclosed in the EN 1991-1-5 of the UK Eurocode. The code is also served as temperature reference especially when steel sub-grade materials are utilized in the building construction. However, it is recommended to further refer to the EN 1993-1-10 of the Eurocode to meet the required standard. Moreover, the UK Eurocode also provided general principles and rules especially during construction and execution o f the building works in order to avoid and prevent accidents in the work site. These guidelines are enclosed in the EN 1991-1-6 of the UK code which included temporary works i.e. cofferdams, falsework, scaffolding and propping system. It also noticeable that new building designs utilized structural materials that are fire resistant. Aside from this, building designers also integrated adequate built-in fire safety measures such as

Select a publicly traded U.S. corporation for which you have a common interest - Essay Example egic business decisions, the company has been able to trade in over 186 million bids, with a sum of over $840 million items being sold with an average of around 800, 000 bids per day. (Schonfeld, 2005) As a result of internet technology a lot of business sprung up, among them being Electronic commerce. The online business started to pick up in the early 1990s, and by around 2000 the business was fully embraced across the globe. Recently, e-commerce industry has experienced an immense development, mostly due to the growth of internet users across the world. More and more people are shifting their attention towards the new shopping model of doing online shopping. (Schonfeld, 2005) E-Bay incorporation provides an online platform for sellers and buyers to interact and trade in various categories of goods and services. There are three segments in eBay namely; payments, marketplaces and GSI Commerce. Since access to e-commerce is universal, and the physical assets to start up this form of business are commercially available, barriers to entry into the industry is quite lower. Now what matters here is the network externalities effect. For instance, it is extremely difficult for a competitor to acquire a bigger share of the users in market where there is relatively huge network externalities. Nonetheless, eBay has managed to secure its position among the top e-commerce websites in the world. However, just like any other industry eBay is subject to competition from companies like Yahoo and Amazon. These companies normally employ tactics such as lowering of price of their services in order to gain competitive advantage. At the moment eBay is focusing its markets abroad. It is now operating in eight of the top ten countries, by e-commerce market size outside the American nation. For example, eBay controls over 80% of e-commerce market in Asia, while it is reported to be gaining users , 45% faster in Europe continent more than in U.S.A. It is also experiencing a 135% growth
