Seismic Response of Vertical Irregular Structures in Setback and Stepped Buildings

Vertical irregular buildings are frequently constructed across the globe for functional as well aesthetic purpose. However post-earthquake reconnaissance survey reports revealed high seismic vulnerability of building with vertical irregularities. Consequently it is very important to explore reason behind and poor performance structures during earthquake. A humble effort under taken considering several case studies comprising different configuration structures, so comprehend behavior structure using response spectrum pushover analysis has been attempted in finite element software ETABS 16.2.1 version. The results indicate have ample chance higher stress concentration displacement demand at vicinity irregularity. Member strength enhancement irregularity may improve overall building. Also, this research checks adequacy fundamental mode properties quantification Furthermore, done observe hinge formation pattern also plastic rotation observing level
