STUDY ON EARTHQUAKE RESPONSE OF BUILDINGS CONSIDERING SITE AMPLIFICATION EFFECT

Abstract

In this paper, the equations to calculate the seismic response of buildings considering precise effect of the soil at the building site are presented. These equations are readily used for the seismic design of buildings. Based on the equations, effect of the strength of building and soil on seismic response was discussed. It is found that seismic responses, particularly those of the buildings with short or long natural periods significantly differ depending on accuracy of soil amplification. Finally, the availability of this calculation method is confirmed by time-history seismic response analysis.
