摘要
Abstract
With the 242 group strong earthquake records of 85 stations at KIK- NET in Japan, the sites was classified as 01 seismic code, the acceleration response spectrum with 5% damping ratio of underground bedrock and surface at each site were calculated, and according to the size of the input ground motion of underground bedrock PGA was divided into four intervals.This article studied the effect of site condition on surface acceleration response spectrum at each site, and concluded Class Ⅱ site with the largest ground motion amplification in short period, Class Ⅰ with the least, after Class Ⅲ site.The result shows the maximum response spectrum adjusted by site classification, proposes the maximum value of site coefficient of various sites design response spectrum.关键词
