摘要:
对某公跨铁立交桥进行了现场静动载试验，测得桥梁结构的力学特性和性能指标，并基于ANSYS建立了该桥的有限元模型，进行了静力分析.通过试验值与理论计算值的比较分析，可以看出该桥承载能力和动力性能均有一定程度的降低，安全性能不能满足营运需要，需要进行大修.本文的研究方法可应用于桥梁结构的损伤识别、健康监测、结构控制以及结构的承载力评定.
Abstract:
The mechanical characteristic and performance index of a highway bridge over a railroad are acquired after the field static and dynamic testing are carried through, then the finite element model of the bridge is set up based on ANSYS and static analysis is performed. Through the comparative analysis between the analytical and theoretical values, it can be seen that the bearing capacity and dynamic performance debased for a certain degree, its safety cannot meet the need of operation. It needs to be completely repaired. The research method can be used in many applications of bridge structures like damage identification, health monitoring, structural control, structural evaluation and assessment.
