| Abstract: | The formulation of the ring analogy method for the prediction of the staticstrength (ductile collapse) of tubular T,X joints under axial compression based on the limit analysis of the ring with some assumptions is presented. The regression formula for the effective length of the chord based on the test data is established by means of the least square method. The results computed by the present semi-analytical formula are compared with the previous test data and they are quite close to each other. |
