Analysis on Buckling Loads for Axial Compression Structures under Corrosion

Because of environmental effects for many years,all steel structures have suffered corrosion,resulting in the change in performance of the steel structures,which causes the security risk for engineerings.In this paper,based on the development rule of steel corrosion in atmosphere and taking H-steel beam for example,the axial buckling loads in atmosphere are analyzed and the changes with times are obtained,providing the basis for durablity design.
