Abstract

Abstract

Hot-rolled heavy H-section steel is defined as hot-rolled H-section steel with a weight per meter not less than 3000 N or a flange thickness not less than 40 mm. This paper reviews the research findings on material properties and residual stress of hot-rolled heavy H-section steel, conducts a comparative analysis of experimental data in accordance with current Chinese codes, and provides some design and application recommendations. The material properties of hot-rolled heavy H-section steel exhibit variability at different cross-sectional locations, and fluctuations in material properties are observed along the thickness direction at the same cross-sectional position. The material property data obtained from sampling based on current Chinese codes can effectively reflect the average material properties of the cross-section of hot-rolled heavy H-section steel. The residual stress distribution in hot-rolled heavy H-section steel differs from that of ordinary hot-rolled H-section steel, showing parabolic or multi-curve patterns in the flange and web regions, with significant variations in residual stress values along the thickness direction at the same location. The residual stress distribution model for hot-rolled H-section steel used in current Chinese codes to determine column stability curves exhibits discrepancies compared to the actual residual stress distribution of hot-rolled heavy H-section steel obtained from the existing research, which may lead to conservative design results.
