Experimental investigation of residual stresses in steel cellular and castellated members
Highlights Cellular or castellated members are fabricated from hot-rolled parent sections. Residual stresses lower the global buckling resistance of the parent sections. The production process influence was determined by measuring the residual stress. During the production process, the residual stresses become more detrimental.
Abstract The global buckling resistance of hot-rolled steel I-section members is adversely influenced by the presence of residual stresses. It is expected that thermal effects during the production of cellular and castellated members will influence the already present stresses in the hot-rolled parent sections, but it is yet unknown to what extent. In this paper, the experimental investigation of the residual stresses in these members is described, and it is shown that the production process increases the already present compressive flange stresses, which will be detrimental for their buckling resistance. This effect will be even more pronounced for deviating production procedures.
