摘要
基于梁格法采用Midas建立2种小箱梁桥模型。为了验证梁格法计算小箱梁桥是否满足精度要求,在保证荷载加载位置和荷载相同的前提下,采用2种梁格法模型和板单元模型分别计算小箱梁的挠度和应力,给出2种模型的误差范围。2种梁格模型的计算结果与板单元模型非常接近,说明所建的2种梁格模型是可靠的。
In this paper,based on the grillage method,the Midas is used to establish two types of small box girder bridge models. In order to verify whether the small box girder bridge calculated by the grillage method meets the actual accuracy requirements,and under the prerequisite condition of ensuring the same load loading position and the same load,the deflection and stress of the small box girder calculated by the grillage method and the plate unit method respectively are compared to give the error range of two grillage models. The calculation results of the two grillage models are very close to those of the plate unit models,which indicates that the two established grillage models are reliable.
