“Evaluation and Comparison of Seismic Parameters of Multistoried Building by Different International Codes”

Abstract

The present’s study is on seismic behavior of structure using different codal provision Indian code, American code and British code for earthquake analysis. This study is carried out on residential building of G+20 story Special RC structure. Modelling of the structure is done using ETABS 2018 software.

The RCC frames are the most commonly adopted buildings construction practices in cities areas. With growing economically, urbanization and non-available of more horizontal space, increasing cost of land and need for agricultural land, high-rise structure sprawling structures have become highly preferable in cities. With high-rise structures, not only the building has to take up gravity loads, but as well as lateral forces. Many important cities fall under high - risk seismic zones; hence strengthening of buildings for lateral forces is a prerequisite.

In the present study, relative seismic performance of G+20 story RCC structures for zone III for medium soil condition using ETABS 2018 software is carried out for different Earthquake Code i.e., IS 1893 2016, ASCE 7-10 and UBC 94. The structures are analyzed and results are compared with different structural parameters viz. Base Shear, Displacement, and Modal Mass Participations etc. Based on results overall performance of building using Indian code and British code are same for earthquake loading, but ASCE code shows 3 times increase in seismic parameters as compare to Indian and British code.
