摘要
采用基于梁格法的基本原理提出槽形梁的空间梁格模型,总结了梁格单元划分和截面特性计算的一般方法,并介绍了空间梁格模型横梁刚度的试算方法以确定出合理的横梁刚度值,最后通过工程实例验证了模型的有效性。
A space grillage model for trough girder based on basic Grillage divided and calculated method of sectional characteristic principles of grillage method is put forward. is summarized. To obtain a reasonable rigidity value of the beam, a trial method for the space grillage model is introduced. And its effectiveness is verified after generalizing rules of grillage meshing and section characteristic by a fact engineering case.
