Abstract：
So the methods estimated of effective width of code for design of steel structures （GB50017-2003）， technical code of cold-formed thin-wall steel structures（GB50018-2002）， America specification （AISC: 2005），European specification（E3-1.5:2006）， and Winter equation are introduced in this paper. The effective area of thin-webbed box members with different width-thickness ratio in web and flange are estimated using these codes. Comparison on these estimated results show that European specification（E3-1.5:2006） and Technical code of cold-formed thin-wall steel structures（GB50018-2002）is application for members with different width-thickness ratio of web and flange . So Technical code of cold-formed thin-wall steel structures （GB50018-2002） can be used to estimate the effective area of thin-webbed box members.
