Comparative study on regular & irregular structures using equivalent static and response spectrum methods

Abstract

Objective: This paper deals with the comparison between equivalent static technique & response spectrum technique. The earthquake effect lead to the damage the property and many people loss of life. So we have to know the structural performance under seismic load before construction. Method of analysis: Adopt the equivalent static and response spectrum techniques to analyze the model for the present study and observe the lateral displacement of the structure in a regular and irregular structure in various zones. Finding: The major parameters considered in this study to observe the seismic conduct of various zones i.e. ZONE-II, Zone-III, ZONE-IV&ZONE-V and the base shear, lateral displacements in various levels. According to IS-1893- 2002 seismic loads are calculated. The lateral forces are calculated by using the STAAD Pro and the results are compared between two Zones in both response spectrum and seismic coefficient technique. Applications: To analyze the building as per code IS 1893-2002 part I criteria for earthquake resistant structure. Dynamic analysis of the building using response spectrum method. Building with different lateral stiffness systems. To get economical and efficient lateral stiffness system.
