Abstract
It was presented an experimental investigation on longitudinal residual stresses of welded H-sections fabricated from high-strength steel sheet with a nominal yield stress of 460 MPa,which was recently developed by Baosteel Group Corporation.Strain gage hole drilling method was used to measure the magnitudes and distributions of longitudinal residual stresses along the cross section.Furthermore,the measured points inside the thickness were stripped to the outer surface to measure the stresses along the thickness of the section.At last,a longitudinal residual stress pattern was proposed based on the test results obtained in this study for the Q460 welded H-sections.
