| Abstract: | The buckling stress of steel beam web under pure shear is analyzed. The bending stress and local compressive stress and tretraint of flange to web is considered, the formula of limit ratio of height to thickness of web is gotten when stiffener is not set up, the simplified formula is given for design use. |
