Residual Stress Tests of High-Strength Steel Equal Angles
Publication: Journal of Structural Engineering
Volume 138, Issue 12
Abstract
Residual stress is one of the most important imperfections of steel structure members because of its significant effects on buckling behavior. To quantify the residual stresses in 420-MPa high-strength steel hot-rolled equal angle sections, an experimental study was conducted by using the sectioning method. The residual stress magnitudes and distributions for 15 sections were obtained, and the effects of the width-thickness ratios were clarified. Based on the test results, it was found that the ratio between the residual stress and the steel yield strength for 420-MPa steel equal angles was much smaller than that of normal strength steel angles; however, the distribution was analogous. The residual magnitudes significantly correlated with the width-thickness ratios of the legs. In addition, calculation formulas for the residual stress magnitudes were proposed in which the width-thickness ratios of the angle legs were taken into account, and three distribution models were established to be incorporated in the buckling analysis. The fundamental research and conclusions presented may provide useful experimental data and calculation methods for further studies on the residual stress and buckling behavior of high-strength steel members.
