| 摘 要： | 城市桥梁在地形和环境的限制下,弯桥和坡桥众多,箱形截面又是桥梁的主要截面。箱形截面梁在进行车辆荷载偏载试验下,桥梁截面上会出现一种弯-扭组合效应。通过理论计算和试验测试数据的对比表明,考虑了弯扭组合效应和不考虑按扭组合效应的结论是有显著区别。

| Abstract: | Lots of bridges in the city are sloping and curve bridges under the constraint of terrain and environment.The box-cross section is the main section of the bridge.In the vehicle eccentric load tests,the box-cross section has a kind of combinational effect with bending and torsion.Through the comparison of theoretical calculation and testing data,it is indicated that the results with the consideration of combinational effect of bending and torsion have remarkable difference with the ones without considering. |
