Comparative Study of Various Seismic Analysis Methods for RC Structure

Abstract: A large number of RC frame buildings have been built in India in recent years. Huge number of similarlydesigned andconstructed buildings exist in the various towns and cities situated in moderate to severe seismiczones of the country. Analysis and design of such buildings for static forces is a routine affair these daysbecause of availability of affordable computers and specialized programs which can be used for the analysis. Onthe other hand, dynamic analysis is a timeconsuming process and requiresadditional input related to mass ofthe structure, and an understanding of structural dynamics for interpretation of analytical results. ReinforcedConcrete (RC) frame buildings are most common type of constructions in urban India, which are subjected toseveral types of forces during their lifetime, such as static forces due to dead and live loads and dynamic forcesdue to earthquake. To ensure safety against seismic forces of multi-storied building hence, there is need to studyof seismic analysis to design earthquake resistance structures. In the present study a multi-storied framedstructure is selected, And Linear seismic analysis is done for the building by static method (Equivalent StaticMethod) and dynamic method (Response Spectrum Method & Time history Method) using ETABS as perthe IS-1893-2002-Part-1. As a result, the response of structure has been obtained for considered buildingmodels, based on each method of analysis, and then the results are compared with each other
