摘要
采用Midas Civil2011建立某斜交简支钢箱梁桥的空间单梁模型和梁格模型,采用Ansys10.0建立该桥的板单元模型,阐述三种模型的建模要点,比较三种模型的有限元计算结果,表明梁格法可以较好的模拟斜交钢箱梁,其方法简单易行,计算结果具有足够的精度。
The software of Midas Civil 2011 is used to set up the space single-beam model and grillage model of a skew simple supported steel box beam bridge, and the software of Ansys 10.0 is used to set up the plate element model of this bridge. The article sets forth the modeling gist of three models, and compares the finite element results of three models. The results show that the grillage model can better simulate the skew steel box beam. This method is simple and feasible. The calculation result has the sufficient accuracy.
