DYNAMIC ANALYSIS AND COMPARATIVE STUDY OF PLAN IRREGULAR (C-SHAPED) BUILDING WITH DIFFERENT TYPES OF BRACING SYSTEM

Abstract

When the multi-storied buildings are constructed a suitable care should be taken while designing, as they are subjected to lateral forces. The behaviour of multi-story building depends upon either in plan or in vertical direction i.e, elevation, is considered as one of the main causes of failure during earthquakes. Thus irregular structures, especially the structures which are located in seismic zones are required a special attention during analysis and design of structure. In this study Plan irregular (C-shaped building) is considered to carry out study. Bracing system is installed to provide strength against lateral loading and the behaviour of the structure in terms of base shear, story drift, stiffness and the lateral displacements are observed. Three different types of bracings X, V and Diagonal are installed in the structure. Total 4 models are analysed for 7 story height level, 4 Models are computed to determine the performance of the structure. One MRF and three models with different bracing system. And the best suitable bracing system for this study. The method used for this study is response spectrum method, to perform dynamic analysis of the structure.
