摘　　要：为研究地震作用下冷弯薄壁型钢-定向刨花板组合墙体的抗侧性能,采用单调加载及低周反复加载对8个9mm冷弯薄壁型钢-定向刨花板组合墙体进行试验研究,得到了试件的破坏特征、荷载-位移曲线及承载力等抗侧性能指标。试验结果表明,加载方式对墙体屈服前的刚度影响不明显,低周反复加载与单调加载相比,会降低墙体的承载能力;在低周反复加载下试件单位长度抗剪墙的受剪承载力设计值较单调加载约降低29.6%;施加竖向荷载降低了组合墙体的抗侧性能。To investigate the performance of a lateral resistance of OSB sheathed cold-formed thin-walled steel wall,an experimental study on eight specimens of the OSB sheathed cold-formed thin-walled steel wall is conducted under monotonic loading and cyclic loading,respectively.The lateral resistance indexes of failure characteristics,load-displacement curves and bearing capacity of the specimens are obtained.The test results show that the loading pattern has little influence on the initial shear stiffness of specimens,but compared with that under monotonic loading,walls under cyclic loading have lower shear capacity.The design values of unit shear strength of specimens under cyclic loading decrease29.6% compared with that under monotonic loading.The lateral bearing capacity of walls under vertical load is lower than that without vertical load.
