Abstract

Choosing proper earthquake ground motion parameters is important to establish a relation between strong ground motion and the earthquake damage. In this paper the statistical relationship between ten ground motion parameters and simulated mean earthquake damage indices of simplified masonry structures is investigated. The ten parameters to be used include time domain peaks and mean values, frequency domain peaks, time durations. Based on the field investigation on the structural earthquake damage conducted in Deayang City, Guanyuan City, Jiange County and Jiangyou City, simplied masonary structures group are generated with main controlling parameters as ratio of different number of stories, ratio of earthquake resist design. To simulate the earthquake damage of masonary structures under strong ground motion, simplied shear type model of masonary structures are used, with main controlling parameters as initial stiffness, first nonlinear stiffness, second nonlinear stiffness, yielding stress, ultimate stress. Using the 139 sets of strong ground motion in 12 earthquakes and thousands of simplied masonary structures, it is found that It is found that effective peak acceleration and peak ground acceleration which indicate the characteristics of force to structure have good relationship with damage of masonry structure, and the story number of masonry structure directly affects the strength of correlation between ground motion parameters and damage of masonry structure.
