  • Residual stresses in high strength steel welded box sections

    1. Introduction. HSS welded box columns are usually fabricated from quenched and tempered HSS steel plates such as Australian manufactured HSS plates or USA manufactured ASTM A514 HSS plates, and both the plates have nominal yield strength of 690 MPa. Fabrication induces residual stresses in a box section due to strain misfit as the weld material solidifies .
