Numerical studies on corroded steel angle members

Abstract

Steel structures corrode when exposed to the corrosive environment such as marine, industrial and humid and hence the strength of steel structural members reduces. Steel angle sections are widely used in transmission line micro wave towers and their performance is effected as they corrode. This paper presents the numerical studies on uncorroded, corroded and retrofitted angle specimens considered as compression members and are compared with experimental results. The cross sections considered are ISA 70 × 70 × 5mm, 75 × 75 × 5mm and 100 × 100 × 6mm. Numerical studies were also conducted by using ABAQUS finite element (FE) based software and the results of the FE models are validated with that of the experimental studies and presented.
