COMPARATIVE STUDY OF REGULAR AND VERTICALLY IRREGULAR BUILDING UNDER SEISMIC LOADING

Ravi Kiran , Sridhar.R

Abstract

It’s a very big challenge that building or structure must withstand lateral forces such as earthquake and wind load. In the present work, the comparative analysis of various structures is performed using SAP 2000. The main aim of the project is comparative study of the stiffness of the structure by considering the three models that is Regular Structure, Plan irregular structure and Vertical irregular structure. All these three models are analyzed with static and dynamic earthquake loading for the Zones II, III, IV & V. The results are tabulated and graphs are plotted for displacement, drift, base shear and time period. Based on the results and discussion the structural behavior and stiffness is concluded for regular and irregular structures, among these structures regular structure shown maximum displacement and drift for all the zones in both static and dynamic analysis.

Keywords: Tall structure, vertical Irregular, Lateral Displacement, Lateral Drift, Base Shear, Time period.
