ANALYSIS OF A STEEL BUILDING AGAINST EARTHQUAKE LOADS

In the world the most widely used material for building construction is Steel. Steel is playing an important role as a building material with combination of concrete as Reinforced cement concrete in the modern days. With the invention of steel as a building material revolution in high rise construction has been started. The genetic properties of steel like strength, toughness, ductility and other appropriate properties made the engineers to select as a building material and also made the characteristics that are useful for seisimic design. As a designer engineer he should know the application of the steel design rules which is given in code books for the seismic applications. The seismic design of building frame in this paper is based on IS 1893-2002 and codal provisions are considered for the design is IS 800- 2007 and STAAD Pro is used for analysis. The present work aims to analyze and design of a multi-bay and multi storied(G+5) steel structure for earthquake forces following IS 1893-2002 and design as per IS 800-2007.The selection of arbitrary sections have been done following a standard procedure and corrections are done accordingly for earthquake loads. The two methods that have been used for analysis are Equivalent static load method and Response Spectrum method. The frame has also been further checked for P-∆ analysis and required corrections has been done and final results are documented. Finally, the design of connection of an interior joint and an exterior joint of the frame have been done and the calculations have been shown and figures are drawn. The cost efficiency of both the methods have been compared
