摘要
在桥梁荷载试验理论分析中,空心板常采用梁格法进行建模,但由于虚拟横梁的截面参数无法确定,导致Midas Civil计算结果会有一定误差。通过对3座在役空心板梁桥荷载试验的实测挠度值与理论值进行对比分析,得出在梁格法建模中虚拟横梁设置方法。
In the theoretical analysis of bridge load test,generally the hollow slab is modeled by the beam grid method,but the undetermined section parameters of the virtual beam will cause some bias on the calculation results of Midas Civil.In this paper,the virtual beam setting method in the beam grid method will be obtained through the comparison and analysis of the measured deflection value and the theoretical value of the load test of three hollow slab girder bridges in service.
