摘要
通过大量的数值计算 ,对反映单自由度体系弹塑性最大相对位移反应和弹性最大相对位移反应两者相互关系的弹塑性位移比谱进行了研究 ,得出了具有统计意义的弹塑性位移比均值谱 。
In this paper, the elasto plastic displacement ratio spectra, which reflects the relationship between the plastic maximum relative displacement seismic response and elastic maximum relative displacement seismic response of SDOF is studied through a great amount of numerical computation. The mean spectra of elasto plastic displacement ratio are acquired, so as to provide the fundamental datum and reference material for further research of simplified method of checking the elasto plastic deformation of structures and for new seismic design method based on elasto plastic displacement of structures.
