梁格法进行曲线箱梁空间分析实例

Analysis on Curved Box Beam Space by Grillage Method

该文以某高速公路立交匝道桥为工程实例,应用三维有限元分析设计程序midas Civil进行梁格法空间分析,重点阐述剪力柔性梁格理论中纵横梁的截面特性计算方法。并与单梁计算结果进行对比,得出两种分析方法反力的差异。

According to the engineering example of an expressway interchange ramp, the three-dimensional finite element analysis design program midas Civil is used for the space analysis of grillage method. The article focuses on the sectional characteristic calculation methods of vertical and cross beams in the shear flexible grillage theory, compares the calculation result with the single beam, and gives the difference of counter force by two analysis methods.
