COMPARATIVE STUDY AND SEISMIC ANALYSIS OF A MULTISTOREY STEEL BUILDING

Steel Building in the world in the last decades, the steel structure for the building industry has played an important role in the most useful content. Providing the strength, stability and flex ibility are the key purposes of seismic design. It is to design a structure under seismic load is required to perform. Structural bracing element in the system plays an important role in structural behavior during earthquakes. Bracing pattern of massive st eel framed building can modify the behavior of the global seismic. In this research time history analysis is carried out for 7 storey and 12 storey steel frame building with different pattern of bracing system. Three types of sections i.e. ISMB, ISWB and I SB sections are used to compare for same patterns of beam, column and bracings. A software package SAP2000 is used for the analysis of steel buildings and different parameters are compared. The property of the section is used as per IS 800:2007 which incor porates Limit State Design philosophy. In this 7 storey and 12 storey steel frame building is analyzed for various types of concentric bracings like inverted V, X and without bracing and Performance of each frame is carried out and studied the comparativel y through time history analysis
