进行了轻钢结构临建房屋骨架结构和整体结构在风荷载作用下的静力试验,对这两个结构的受力性能和变形性能作了考察.利用一种新的分配梁体系对结构施加水平荷载,较好地模拟了均布风荷载的作用,并得到了结构的侧移变化情况和荷载-应力曲线.通过对比整体结构与骨架结构在侧移和应力两方面的差别,发现墙面板的存在可以较大地改善水平荷载作用下结构的受力性能并显著提高其整体刚度.对轻钢结构临建房屋在水平风荷载作用下的静力性能进行了总结和讨论.
Static tests were conducted on frame structure and integral structure of light steel temporary buildings under wind load.Mechanical behaviors and the deformation performances of the structures were investigated.A new kind of system of load distribution beams was applied,which imposed the horizontal loads and simulated the uniformly distributed wind load.The load-displacement curves of the columns,as well as the strains of the columns and the wall panels,were measured and obtained.The test results of the integral structure and the frame structure were compared,to indicate that the presence of wall panels may enhance the overall stiffness of the structures significantly.The performances of the light steel temporary buildings under wind load are summarized and discussed.
