【摘要】 本文采用结构分析软件SAP2000,对某双索面斜拉桥进行有限元建模,来分析其抗震性能。对过模拟分析,该桥属于长周期结构,自振特性较好,结构之间耦合性好,在地震中产生的内力、位移符合规范设计要求,抗震性能较好。更多还原

【Abstract】 Adopting the structural analysis software SAP2000,this paper performs a finite element modeling on the double cable plane cable-stayed bridge to analyze its seismic performance.By the simulation analysis,the bridge is the long-period structure,and its self-vibration characteristics and the structure coupling are good,and the internal force and displacement produced in earthquake conform to requirements of the normative design,and its seismic performance is good.更多还原
