Numerical investigation and design of aluminium alloy channel section columns at elevated temperatures

Aluminium alloys are increasingly popular in structural engineering applications because they have high strength, low weight and great durability. However, the mechanical properties of aluminium alloy material may be significantly affected by temperature. This paper presents a numerical study on behaviour channel section columns at elevated temperatures. A non-linear finite element (FE) model was developed validated against 27 experimental results The FE used to conduct an extensive parametric study, which total 360 were generated key parameters for include two types (6061-T6 6063-T5), three lengths (360 mm, 1000 mm 2000 mm) ten temperatures (range from 24 °C 600 °C). design strengths calculated using American, Australia/New Zealand European Standards compared with study. In addition, reliability analysis assess level considered methods.
