【摘要】 借用MIDAS/Civil有限元程序,对吊杆的不同损伤状态进行了仿真,分析对比了桥梁完好状态和不同吊杆损伤情况下的桥梁动力特性,这对正确认识斜靠式拱桥在不同状态下的结构动力特征,合理评价桥梁运营阶段的健康状况提供了参考和基础性数据.更多还原

【Abstract】 This paper simulates the different degree damage of the suspender by MIDAS/Civil Finite element software.Calculated and compared the bridge’s dynamic properties in the different degree damage of the suspender.This provides a reference and basic data for understanding correctly the structural dynamic properties of double X-arch bridge in different states and evaluating reasonably the health status of double X-arch bridge in operational phase.更多还原
