Recommendation of Revisions on Code for Design of Steel Structures GB 50017-2003

This paper recommends that the revisions on "Code for Design for Design of Steel Structures GB 50017-2003" can be divided into two parts: the first part is the code body and the second part is the explanations of the clauses corresponding to the body. This paper recommends that it is necessary to develop unified ultimate strength capacity expressions for steel members and connections,to establish the column curves of axially loaded compression members including the equivalent slenderness ratio for flexural-torsional buckling of axial compression columns and the calculating method of the flexural-torsional buckling critical moment of beams. It is better to develop a new chapter for framed structural design.
