【摘要】 组合梁充分利用钢材和混凝土材料的优点,采用钢梁和混凝土翼板共同受力的横向承重构件。通过建立波纹腹板H型钢组合梁的受力模型,讨论其截面上的应力分布和极限剪力,认为应当考虑混凝土翼板和钢梁腹板共同承受剪力。随后通过有限元方法进行验证,证明在腹板较为纤细的情况下,当混凝土翼板的剪跨比小于8时,若钢梁腹板抗剪承载力不足,可以考虑计入混凝土翼板的抗剪作用。更多还原

【Abstract】 Taking full advantage of steel and concrete,the composite beams are built up by profile steel and concrete slabs.By establishing the model of composite beams with corrugated steel webs,the stress distribution and ultimate shear strength are discussed.Then the finite element method was used to verify the conclusion.By the analysis above,it is think that the concrete slabs’ shear effect should be taken into consider when the shear span is less than 8.更多还原
