中文摘要：

首先以一座钢桁架连续梁桥为工程实例，建立尽可能考虑结构特点的初始有限元模型，并结合现场试验采集的静、动力实测数据，建立考虑变形、频率及振型等静、动力信息的多目标函数，通过有限元模型修正获得能够反映结构真实状态的基准有限元模型；其次介绍了梁格法桥梁车桥耦合振动分析模块以及静载试验整车加载模块编制思路，并嵌入自行研发的桥梁结构动力分析软件BDANS；最后将修正后的有限元模型输入至自行研发的梁格法车桥静动力分析模块，并将静动力荷栽工况下的实测响应、BDANS计算值与通用软件ANSYS计算值三者进行了相互校核和对比。结果表明：BDANs静力分析模块的计算结果与ANSYS静力计算结果完全吻合，BDANS动力分析模块在不同行车工况下的动力计算响应趋势与实测响应趋势保持一致，从而验证了该分析模块的可靠性。

英文摘要：

Firstly, taking a steel truss continuous bridge as an example, an initial finite element model considering structure properties was fully developed, and the static and dynamic test data collected on the spot were used to establish the multi-objective function based on deflection, frequency and mode, so the reference finite element model was acquired through finite element model updating. Secondly, the analysis modules of the vehicle-bridge coupling vibration with grillage method and full vehicle load of static test were introduced, the modules were embedded in self-developed dynamic analysis software BDANS. Finally, the updated finite element model was inputted into the self-developed static and dynamic analysis module of vehicle-bridge with grillage method, and the measured responses under static and dynamic load cases, the calculated values in BDANS and ANSYS were examined and compared comprehensively. The results show that the static values calculated in BDANS have good agreement with those in ANSYS, calculated responses under different load cases are consistent with measured dynamic responses for BDANS dynamic analysis module, so the validity of the compiled module is verified
