STATISTICAL STUDY OF SPATIAL VARIATION OF RESPONSE SPECTRUM

抄録

Spatial variation of acceleration response spectra is examined using strong motion records for a large number of events from dense accelerometer arrays at Chiba in Japan and SMART-1 in Lotung, Taiwan. The effects of earthquake component, structural damping, earthquake magnitude, focal depth, epicentral distance, structural time period, and station separation on the intra- event variation of response spectra are examined first through an empirical analysis and then through a least square regression fit for parametric study.
