钢板剪力墙已在高层建筑中开始得到应用,国外已有钢板剪力墙的设计规范,但中国对钢板剪力墙的设计方法规定还比较保守,其设计准则仍基于厚钢板墙的设计理念.本文根据美国规范AISC-341 2005、加拿大规范CAN/CSA S16-01以及中国的高层建筑规程对非加劲钢板剪力墙的设计过程进行了对比,对墙板的抗剪承载力,尤其是对薄板屈曲后形成拉力场的性能进行了相关实例的计算,并对设计结果进行了比较.结果表明,美国和加拿大规范在高厚比较大时,能较准确反映墙板的抗剪承载力；中国规范只是在高厚比较小时能准确计算其抗剪承载力,高厚比较大时,既不准确,也不经济.%Steel Plate Shear Wall( short for SPSW) structures are beginning being used in structural application. Until now,there have been several design codes for unstiffened SPSW at abroad. However,such a specification on SPSW been prescribed in China is more conservative,whose design criteria is still based on the concept of thick SPSW design. According to American (AISC -341 2005) , Canadian (CAN/CSA S16 -01) and Chinese high-rise building regulations, the unstiffened SPSW was contrasted in the design process. The related example in calculations was given and the results of the design were compared. The item to be calculated here is the shear resistance, especially the postbuckling strength after the thin wall buckling and forming the tension field. The results show that the correlative provision in America and Canada can more accurately reflect the shear resistance of the wall with large height-thickness ratio. However,the provision in China can only accurately reflect it with small height-thickness ratio, which is not accurate or economical for thin plate wall.
