Abstract
Aluminum Alloy Gusset joints (AAG joints) have the advantages of simple form and ease of erection, they have been widely used in single-layer reticulated shells. Numerous studies have been conducted to investigate the bearing capacity of AAG joints at ambient temperature. However, the available research results on the bearing capacity of AAG joints at elevated temperatures are very limited. In order to reveal the bearing capacity of AAG joints at elevated temperatures, finite element models of AAG joints at 25℃, 100℃, 200℃ and 300℃ were established by using the nonlinear finite element software, ABAQUS. The failure modes of AAG joints at elevated temperatures were inquired. The bearing capacity of block tearing and bearing capacity of buckling within the central area at elevated temperatures were obtained. The research results indicated that the bearing capacity of block tearing was related to the tensile strength of aluminium alloy at elevated temperatures.
