| 摘 要： | 钢-混凝土组合梁下通过的管道会导致建筑层高的增加而减小组合结构的优势。腹板开洞的钢-混凝土组合梁有效的减小了梁下所需的空间，从而在工程上解决了该问题。但是，洞口的存在影响了钢-混凝土组合梁的受力性能。文章利用ANSYS有限元软件对腹板开洞压型钢板组合梁进行了非线性分析，探讨了洞口处弯剪比对腹板开洞组合梁受力性能的影响。分析结果表明，洞口位置靠近加载点或者支座处都会削弱组合梁的承载力，而组合板对腹板开洞组合梁的抗剪承载力贡献很大，在计算中忽略的话是偏于保守的。

| Abstract: | Passing utility ducts under the composite steel-concrete beam results in a larger floor height and decrease of the advantage gained by using composite steel-concrete construction.The use of composite beams with web openings offers an engineering solution for this problem by eliminating the space required under the beams.However,the presence of such openings affects the behavior of composite beams.ANSYS is used to an-alyze the effects of moment-shear ratio on composite beam with profiled sheeting.Results sho... |
