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 highrise 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 heightthickness the provision in China can only accurately reflect it with small heightthickness ratio, which is not accurate or economical ratio. However, for thin plate wall. Key words: unstiffened steel plate shear wall; design code; shear resistance; postbuckling strength
