Local Buckling of 2A12 Angle Aluminum Alloy under Axial Compression

Abstract

The limiting width-thickness ratio of 2A12 angle Aluminum Alloy under axial compression is discussed using guide for design of transmission tower by American society of civil engineers, Chinese Technical regulation of design for tower and pole structure of overhead transmission line (DL/T5154-2002) and Chinese code for design of steel structures (GB50017-2003). The results show that the formula of Chinese code for design of steel structures about limiting width-thickness ratio is reasonable. And there is unreasonable in Chinese technical regulation of design for tower and pole structure of overhead transmission line and guide for design of transmission tower by American society of civil engineers about the formula of limiting width-thickness ratio. Some useful suggestions are given.
