梁格法在桥梁建模中的应用分析

摘要

The paper introduces the theory of the beam grid method in the spatial analysis of bridge structures, undertakes the modeling compari- son analysis of the typical flat broad box girder by adopting the plate-shell element model, the one-layer beam model and the beam grid model, and displays by the results that the calculation accuracy of the beam grid method can meet the engineering demands.%首先介绍了桥梁结构空间分析的梁格法理论，对一典型的扁平宽箱梁分别用板壳单元模型，单梁模型及梁格法模型进行建模对比分析，结果显示梁格法计算精度满足工程需求。
