摘要
钢梁腹板开洞的压型钢板组合梁的承载力较未开洞组合梁有所下降,一般的组合梁在弯矩和剪力最大处发生破坏。但开洞组合梁的破坏不仅发生在这些地方,而且还会发生在洞口处。文章着重介绍钢梁腹板开洞的压型钢板组合梁承载力的计算方法,并讨论了其存在的不足。
Compared to the unperforated beams, the bearing capacity of composite beams with web openings are decreased. Unperforated beams are destroyed at the places which the maximum moment and the maximum shear are obtained, but perforated beams are destroyed not only at the places, but around the openings also. The way to calculate bearing capacities of composite beams with web openings is introduced, and then the shortcomings of them are pointed out.
