The construction industry has been increasingly using aluminum alloys as a construction material due to their advantageous features such as exceptional corrosion resistance, and appealing appearance. Despite these benefits, the conventional structural aluminum alloys have relatively lower material strength compared to structural steels. This impedes the wider application of aluminum alloy structural members. With the advances in manufacturing techniques, high-strength aluminum alloy product has been developed recently, the material strength of which is more than twice the strength of the conventional structural aluminum alloys. However, the structural performance of high-strength aluminum alloy members has not been verified. This project aims to fill this research gap by conducting experimental and numerical investigations on the structural performance of high-strength aluminium alloy stub columns.
