Abstract:

Now-a-days structures are designed based on Force Based Design (FBD) using traditional seismic design codes (IS 1893:2002). Inadequate response reduction factor, Initial-stiffness categorization of structures, and design fundamental time period is based on height dependent formula this problems are associated when building subjected to seismic loads. For finding the solution of those problem need to develop alternatives design approach which based on Performance Based Seismic Design (PBSD) is Direct Displacement Design Approach (DDBD). DDBD is the new concept for seismic design of structures. In PBSD procedure Direct Displacement-Based Design (DDBD) approach is one of the available approach, which is implemented in this study. Design and analysis is done for regular R. C. building frame of 4, 8 and 12 storey based on IS 1893:2002 by using two design approaches. The performance evaluation of buildings designed by FBD and DDBD is done using nonlinear static pushover analysis in accordance with FEMA 356 using SAP 2000 v.18.2.0. The results of analysis are compared with FBD and DDBD approach in terms of base shear, storey drift, number of hinge formation for achieving same performance level.
