| 摘 要： | 为了确定钢筋混凝土单箱多室箱梁在剪扭组合作用下的极限承载力,该文基于箱梁剪扭理论,提出了一种通过验算单箱多室箱梁每个板件的极限抗剪承载力来确定整个断面剪扭承载力的方法。笔者通过试验对该方法进行了验证,试验结果表明,采用该方法计算单箱多室箱梁的抗剪扭极限承载力是可行的,按此方法计算得到的单箱多室箱梁的抗剪扭极限承载力的安全储备系数可以达到2.54。该文为钢筋混凝土单箱多室箱梁在剪扭作用下极限荷载的确定提供了理论计算方法,利用该方法能较好的预测单箱多室箱梁在剪扭作用下的极限荷载。

| Abstract: | In order to determine the ultimate bearing capacity of the original box girder subjected to the torsion and shear action,based on the theory of shear-torsional of the box girder,a method of calculating the ultimate bearing capacity by checking the shear capacity of each plate of box girder is brought forward.Comparing the ultimate bearing capacity of the theory analysis result with that of experiment,conclusions are got that this method can predict the ultimate bearing capacity well and the security reserve... |
