On the condition that the maximum stress of web is considered directly, it is put forward that the calculating formula of the limit of height to thickness ratio of web of steel member with flexure and axial load. The formula can be applied to check computations of the local stability of web of member with flexure and axial load under indirect dynamical load. It can be omitted that the supplement check of effective area method in code for design of steel structures. The calculations of examples show the formula is suitable to use in the design of engineering.

Keywords: web; height to thickness ratio; limit; stress; correction
