用ANSYS对T梁和空心板梁桥进行结构仿真分析的研究

Study on Simulation of T-shaped Beam and Hollow Slab Bridge by ANSYS

本文介绍桥梁三维造型系统Bridge3D软件和大型通用有限元软件ANSYS的接口程序的开发。用接口程序能够将Bridge3D中的桥梁参数转换成用ANSYS进行结构三维仿真分析的三维实体单元结点数据,并对T梁桥和空心板梁桥进行全桥空间仿真分析。通过ANSYS的计算结果与荷载横向分布理论的计算结果相比较,分析与讨论了简支T梁桥和空心板梁桥荷载横向分布计算方法的适用性及其精确性问题。

An interchange program combines Bridge3D with ANSYS will be introduced in this paper. The interchange program can transform the parameter information of Bridge3D into the information of element and node for structure simulation analysis with ANSYS. Some numerical results from ANSYS are compared with these from transverse distribution of load theory to reflect the applicability and accuracy of transverse distribution of load theory of T-shaped beam bridge and hollow slab bridge.
