Abstrait:

Welding technologies are widely applied in all kinds of steel structures. No matter what kind of welding is used, the welding residual stress is always inevitable. So, in this research, a semi- destructive experiment and a numerical simulation are conducted to study the welding residual stress distributions of shear keys in the grouted connection section. The experiment uses the blind hole method on 3 flat-plate specimens of the sleeve section, to measure the welding residual stress distributions of them, which gives an approximate distribution of the real grouted connection section. Based on the experiment, a FEM numerical simulation is performed to estimate welding residual stress distribution. During the numerical simulation, EBD (Element Birth and Death) and Dflux subroutine are applied to maintain a better precision. Through the experiment and simulation, a comparison is done and a good correlation between welding residual stresses was found.
