爆破地震波三要素对多层砌体结构弹塑性地震响应的影响
Effects of three main factors of blasting seismic waves on elastic-plastic seismic response of multistory masonry buildings ＊
摘要
Abstract
A set of programs for solving elastic-plastic seismic response of multistory masonry buildings was written by Matlab, which combined Newmark time-history method with two-linear model of stiffness degradation. A four-story masonry building was taken as the analyzed object, and the actual and artificial-simulated blasting seismic waves were used as the input loads, whose characteristic parameters were transformed based on a certain principle. According to calculated results of amplitude for all structural elastic-plastic seismic response, effects of amplitude, dominant frequency and duration of blasting seismic waves on elastic-plastic seismic response of multistory masonry buildings were discussed respectively. The present study will provide theoretical and numerical experiment foundation for establishing multi-parameter safety criterion of blasting vibration and assessing blasting seismic effects of buildings in blasting zone.关键词
