用板梁元素组合法计算T型截面梁桥

Computing the Beam Bridges with T-Shaped Cross Sections by the Combination Method of Plane Beam Elements

用有限元素法中的板元素与渠元素组合计算 T 型截面梁桥(以下简称 T 梁桥)并时文献[1]中带有横隔梁的实验模型进行了计算.计算结果与实验结果比较,挠度衰减较小;截面弯矩误差也基本满足工程要求.

This paper introduces a method to compute the bridges with T-shaped cross sections (briefly,T-Beam Bridge).The model of experiment with Crossbeams in reference [1] is calculated.Compared with experimental results,the loss error of displacement becomes smaller and its moment error of cross sections basically meets the engineering needs.
