Abstract

Response Spectrum Analysis for Regular Multistory Structure in Seismic Zone III

Highlights

  • Earthquake causes the random ground motions in all directions, radiating from the epicenter

  • The response spectrum represents an interaction between ground acceleration and the structural system, by envelope of several different ground motion records

  • The computational advantages in using the response spectrum method of seismic analysis are the prediction of displacements and member forces in structural systems

Summary

INTRODUCTION

Earthquake causes the random ground motions in all directions, radiating from the epicenter. For the structure to perform better during the earthquakes, it must be analyzed and designed as per the Indian seismic code IS 1893 (Part 1) 2002. Earthquakes causes ground to vibrate and structures supported on ground are subjected to this motion. 2. To study story displacement, story shear, story drift using response spectrum analysis for a regular multistory building. 3. To study response spectrum analysis of regular multistory building using computer programs (STAADPRO,ETABS) B. The computational advantages in using the response spectrum method of seismic analysis are the prediction of displacements and member forces in structural systems. The method involves the calculation of only the maximum values of the displacements and member forces in each mode using smooth design spectra that are the average of several earthquake motions. For any structure with t
