Comparative Study of Performance Based Seismic Design (DDBD) and Conventional Design (FBD) Approach, Applied On an Irregular Tall Building Using Non-Linear Dynamic Analysis

Extensive researches in the field of earthquake resistant structural designing techniques have taken place in past few years and several new methods providing far better results than the conventional methods have been proposed. Force Based Design (FBD) or the conventional designing approach and Direct Displacement Based Design (DDBD) or performance based approach are the two widely popular design approaches. As the use of structural analysis and designing software’s is more popular these days, so with the help of ETABS Ultimate 15.2.2 three models of a G+11 irregular tall hotel building are designed (model-1 based on FBD method using IS-1893(PART-1) : 2002 norms, Model-2 based on DDBD method using IS-1893(PART-1) : 2002 norms, Model-3 based on DDBD method using ASCE 7-10 norms) and the demand parameters are compared for eight different set of spectral accelerations. Performance based is a comparatively new approach but as its working has a harmonious combination of efficiency and economy it provides excellent results.
