Non-Linear Static Analysis of RC Framed Buildings With Plan Irregularity

Herein present study 3 new R.C structures of unsymmetrical in plan (irregular) (designed as per IS 456:2000) is taken for analysis: 4, 8 & 20 storey cover the large variety of low rise building, medium rise building & high rise building constructions. For different modeling were included through three models for every buildings were bare frame with no infill wall, with infill wall as membrane, replacing infill wall as equivalent diagonal strut in earlier model. The equivalent strut method is convenient for modeling the walls in a large buildings. The pushover analysis carried out by using ETABS 9.5. Buildings situated in Zone-IV have analyzed for comparative studies prepared for above membranes. The analysis results are measures in terms of Story Displacement, Drift ratio and Forced Responses such as Base Tensional Moment & Base Shear. Structures were designed to obtain the performance level, allow immediate tenancy, is defined as performance based design. CSM (capacity spectrum method) is used for seismic performance of RC Structures.
