Load bearing Capacity of Aluminum Alloy T stub Joints

Abstract:

On the basis of Kulak prying model, the formulas for calculating ultimate load bearing capacity of T stub joints in Chinese code and European code are verified and compared. Tests of 25 T stub joints consisting of 9 groups are conducted. Furthermore, large scale of numerical parametric analysis is performed to investigate the influence of several geometrical parameters on the behavior of aluminum alloy T stub joints including failure modes, ultimate load bearing capacity and effective length of flanges. Based on the test results and numerical results, the model and assumptions of T stub joints are modified. Finally, the correction formulas based on EC9 are obtained.
