摘要
文章以某大桥为例,采用BEAM3单元建模对大桥进行梁单元划分,通过绘制控制截面弯矩影响线,确定各种试验工况下的车辆荷载布置方案,并将试验荷载弯矩计算值与设计计算弯矩值比较,得出布载方案可行与否的结论。
In this paper, as an example of a bridge, using BEAM3 element modeling to divide bridge beam element. By controlling and mapping section bend influence line, identifying the vehicle load disposal program under diffrent test conditions, and compared test load bend calculation with design bend calculation, draw the conclusions that the disposal pragrams are feasible or not.
