Notes:
TMCP steels produced by thermo-mechanical control process are now spot lighted due tothe excellent combinations of strength, toughness and weldability. Recently, in Korea, high strengthSM570-TMCP steel whose tensile strength is 600MPa has been developed and applied to steelstructures due to its excellent nature. But, for the application of the TMCP steel to steel structures, it isnecessary to elucidate not only the material characteristics but the mechanical characteristics ofwelded joints. In this study, high temperature tensile properties of the SM570-TMCP steel wereinvestigated through the elevated temperature tensile test and the characteristics of residual stresses inwelded joints of the TMCP steel were studied through the three-dimensional (3-D) thermalelastic-plastic finite element (FE) analysis on the basis of mechanical properties at high temperaturesobtained from the experiment. The results are then compared with the conventional quenched andtempered high strength SM570 steel
