Abstract:

The Y-joint is formed by welded together the brace and chord element at an acute angle. The main feature of this joint is that the brace's external diameter is less than the external diameter of the chord. In this paper, the effects of in-plane bending load acting on the joint were investigated. The results are presented in stress concentration factor (SCF) distribution induced around the joint between chord and brace. There are two in-plane loads considered in this study, namely closing and opening in-plane bending loads. The analysis found that the maximum SCF of 3.002 occurred in the area of crown position ( = 0o) of the chord under the closing mode of in-plane bending. Thus, the discussion in this paper focused on closing the in-plane load on the joint. The finding also indicates that the chord experienced higher SCF as compared to the brace. The results were compared with previous studies, and it shows a similar trend of SCF distribution around the Y-joint.
