STUDY OF THE BEHAVIOUR OF WELDED T-JOINTS IN HOLLOW CIRCULAR STEEL SECTIONS

Abstract

A study of the behaviour of welded T-joints in circular hollow sections, conforming to Indian Standards, when subjected to static loading was done under the above project head. The study was structured in such a way that the works include design of hollow section T-joint, fabrication of specimens based on the design data and testing them under static loading and studying the various failure modes based on the experimental results. An analytical work is also conducted to validate the experimental programme. The joint strength obtained from experimental works was compared with design strengths obtained from IS 806:1968 and CIDECT GUIDE-1. The results obtained indicated a close correlation between experimental values of joint strength and design strength predicted based on CIDECT GUIDE-1. It was also found that IS 806:1968 overestimates the joint strength and hence can lead to unreliable design.
