Experimental investigation of welded T-end connection to circular hollow section (CHS)

This paper presents the results of an experimental investigation into the behaviour of welded T-end connections to circular hollow section (CHS) members subjected to axial tension. A total of 22 specimens were tested to failure. Parameters considered for the investigation were the tube size and the cap plate thickness. The cleat plate thickness was kept constant for all tests. The cleat plate orientation relative to the tube was investigated and was found to affect the joint strength. There was evidence of shear lag taking place. The finite element analysis was used to predict the failure loads and comparison is made with the test results.
