3D FINITE ELEMENT NUMERICAL SIMULATION AND ANALYSIS OF RESIDUAL STRESSES ON PLATE JOINTS OF MEGA STEEL STRUCTURE

摘要：

Based on the mega plate joints appeared in the construction of Guangdong Science Center, the numerical simulation and analysis of residual stresses on plate joints has been performed. The mechanics performance of plate joints in mega steel structure is very complex, and the welds have been mustered together, so the welding residual stresses in the plate joints are very large, and they are cannot be eliminated easily, and the property of welding residual stresses in the plate joints should be researched and analyzed. ANSYS, a software program on finite element,with the method of coupling between thermal and structural field and the technique of element birth/death, was applied to calculate the welding residual stresses, and the properties and reasons of residual welding stress and residual welding deformation were analyzed. The paper may be helpful to the other similar simulations of residual stress in the future.
