Welding Residual Stress of Flange-Plate Steel Reinforced Connections

Abstract:

The welding joint method is usually applied in the reinforcing process of the steel moment frame connections. The welding parameters are chosen and discussed and the finite element analysis is employed to analyze the completely penetration joint weld between the flange plates and the column flange. The three-dimensional thermo-structure simulation is conducted. Furthermore, the influence of the residual stresses on the the loading capacity of the reinforced connection is discussed. The temperature field during the welding process and the residual stresses distribution are given. The existence of the welding residual will highly increase the likelihood of brittle fracture of the steel in the heat affect zone.
