| 摘 要： | 本文对桥梁工程中广泛应用的箱形截面拱进行了横向屈曲模型试验研究,模型采用有机玻璃制作,并在两片拱之间设置了不同数量的横撑。荷载由恒载和集中荷载两部分组成,试验结果和有限元计算相符。文中还用有限无法分析了横撑刚度对临界荷载的影响。

| Abstract: | The lateral buckling on the widely used box-girder parabolic arch in bridge engineering is described.The arch models braced with transverse bars,are made of polymethyl methacrylate.The acted loads include uniform and concentrated load.The test results are correspondence with the FEM results.Also,the effect of the transverse bars' rigidity on the buckling load is studied by FEM. |
