摘要
交错桁架结构的楼板在整个结构传递水平力过程中起到重要作用,为了研究交错桁架结构楼板的受力性能,对1个3层1/3缩尺的钢管混凝土柱交错桁架结构进行了水平加载试验。结果表明:90%以上的水平荷载由楼板传递到下层相邻桁架的上弦杆中。在水平荷载作用下楼板剪应变呈现抛物线分布。楼板的剪切变形很小,可以起到刚性横隔板的作用。
Floor of staggered truss structure is important for transfer later load to adjacent trusses below. In order to research load capacity of staggered truss structure floor, one 3 story 1/3 reduced scale concrete-filled tubular steel column-staggered truss structure model test under lateral load is presented in this paper. The result of the test indicates that the floor transferring 90 % later load to adjacent trusses below. Shear strain of floor is parabolic curve distribution pattern under lateral load. Shear deformation of the floor is very small and the floor can be as rigid diaphragm.
