摘　　要：就高强轻质混凝土桥梁结构对地震响应的影响进行了比较分析,分析结果表明:高强轻质混凝土能有效地减小桥梁高阶自振周期,减小桥梁结构的地震内力响应和位移响应,同时,对于同一强度的高强轻质混凝土,其密度和弹性模量的改变对于桥梁结构的地震响应影响不大。The analysis seismic performance of high-strength lightweight concrete bridge is presented in this paper. The results show that, the high-strength lightweight concrete could reduce the high order model period. The internal force response and displacement of high-strength light weight concrete bridge is smaller than that of common concrete bridge. And on the same time, for lightweight concrete of same strength, the den sity and elastic modulus of have a little effect on the seismic response of the bridge.
