Design Criteria for Steel H-Columns under Biaxial Loading.

摘要

Several design criteria for steel H-columns subjected to compression and combined with biaxial bending are discussed. The load carrying capacity of the columns is presented in terms of interaction surfaces. Three classes of problems are considered:short columns,long columns under symmetrical loading,and long columns,long columns under symmetrical loading,and long columns under unsymmetrical loading conditions. The interaction surfaces are given in forms of tables suitable for analysis and design. Simple approximate formulas are also developed as an alternative method for the designer. The results are compared with the current Column Research Council design formula. (Author)
