Load-bearing Capacity of Aluminum Alloy T-stub Joints

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.
