Rigidity of Steel-Concrete Composite Beams

Institute of High Performance Structures, Zhejiang University, Hangzhou 310058, China

摘要: 推导了钢-混凝土组合梁的等效抗弯刚度,发现它由两部分组成:一是楼板和钢梁各自绕自身形心轴的抗弯刚度,二是楼板作为上弦、钢梁作为下弦、栓钉作为腹杆的桁架刚度,并给出了简单计算公式,同时介绍了剪切挠度和栓钉抗滑移刚度。

Abstract: The equivalent bending rigidity of steel-concrete composite beam was derived, it was found that the rigidity was composed of two parts: one is the bending rigidities of the slab and the steel section about their own centroid axes, the other was the truss stiffness whose upper chord was the slab and lower chord was the steel section and the studs were the web members, and a simple calculated formula was proposed. The deflection due to the shear strain of the steel web and the interfacial shear-slip stiffness of the stud are also presented.
