DYNAMICS OF TUBULAR SEMI-RIGID JOINTS

An assumption of rigidity of joints in all framed structures has a major influence on strength and stability behaviour of those structures. The objective of the present paper is to show a method to determine the behaviour of tubular joints, as to improve modelling of framed structures in their serviceability performance. The linear theoretical model is used here to dynamically evaluate the rigidity of a joint. The proposed method in nondestructive and has been used previously for open sections by Kohoutek (1988).
