Seismic Assessment of Reinforced Concrete Framed Structures

The design and construction of earthquake resistant structures can counter the aspect of the earthquake hazard with effective application of engineering knowledge. Most seismic design codes today include the nonlinear response of a structure implicitly through ‘Response reduction factor’(R) by IS 1893 (Part I):2002.This factor allows a designer to use a linear elastic force-based design while accounting for non-linear behavior and deformation limits. Performance based seismic design method which is recent path of seismic assessment, both efficient and effective to avoid future earthquake losses. In this work, performance based seismic design of buildings by pushover analysis method in four different seismic zones II, III, IV and V studied. For analysis building models of G+12, G+16 and G+20 stories, plan rectangular shaped generated by a computer program SAP 2000(version 19).In this present work attempt is made to study and obtained Response Reduction Factor in different zones II, III, IV and V. Also different parameters like displacement, drift, pushover curves, performance point and plastic hinge mechanism studied
