摘要
以现有连续桁架桥的静活载作用下实测竖向挠度为依据,进行了挠度的有限元模型仿真计算,验证了所建模型的可靠性,并将其应用于桥梁的承载力评估,同时介绍了ANSYS软件中的一些建模技巧。
On the basis of testing the deflection the static live loads of existing continuous steel truss bridges under the static live loads, the paper simulates, with a finite element model, and verifies the reliability of the model. And the model is used to estimate the bearing capacity of the existing bridges. And this paper also generalizes the modeling skills in the ANSYS environment.
