- Abstract
A parametric analysis was carried out to investigate the gusset plate to CHS XX joints with the finite elements method. The effects of web loading proportion, geometric parameters and axial stress in chord on the failure modes and the ultimate strength were employed. It is found that the web loading proportion have different effects on the ultimate strength with different angles between two gussets. And the ultimate strength of joints decreased no matter the axial stress in chord was positive or negative. Based on the regression analysis, a formula was proposed for predicting the ultimate strength of the gusset plate to CHS XX joints.
