摘　　要：对两层可移动钢结构房屋结构进行水平风荷载作用下进行静力测试及有限元分析,考察该类结构的受力和变形性能以及节点连接的作用机理。试验结果表明,轻质复合墙体对可移动钢结构房屋整体抗侧刚度的贡献显著,而节点构造导致的钢框间连接处错动将大大增加房屋结构的水平侧移。对房屋结构进行有限元模拟和分析,有限元分析结果与试验结果吻合较好。The static test and finite element analysis of removable steel structure houses were conducted under lateral wind loads. The mechanical behavior and deformation performance of such structures were investigated,as well as the action mechanism of the connections. The test results showed that light-weight composite walls contributed a lot to the overall stiffness of removable steel structure houses,and the horizontal deflections of the structures could be greatly increased by the relative shifting of the separate box units which were caused by joint structure. The tests were simulated and analyzed by finite element method and the analysis results agreed well with the test results.
