Fine Stress Analysis and Strength Prediction of Joints in Axial Shear

Abstract:

A fine analysis model for joints in axial shear is given on the base of observation of experiment. Failure of the pin connecting adherends is due to combined deformation of pressure-shear. Both critical region of the pin and the stress state in critical rejoin are evaluated. Ultimate load Fu of the joint in axial shear is evaluated with strength criteria. The following conclusions are obtained. (1) Fu is related to ratio of adherend thickness t to length L. Fu increases with t when t/L is less than 0.1 and hold as a constant when t/L is greater than 0.2; (2) Fu can well be predicted by bi-shear theory or maximum tension strain criterion, but not by Tresca and Mises criteria; (3) Although traditional approximate calculation method of connections is widely used, related experiment must be done for obtaining ultimate shearing stress. Thus, the fine analysis method presented in this paper is useful for stress analysis and strength evaluation of connections.
