Design Method of Steel Girders Considering the Post-buckling Strength of Web Plate

This paper advances a design method of selecting initial cross sections of steel girders when designing steel girders on the basis of considering the post-buckling strength of web plates.Calculations show that when designed by the method proposed in this paper,the initial selecting cross section can pass the checking computations on its first selection,and generally can be a fine cross section with relatively lower steel consumption.
