Characterization of the Material Properties of Rolled Sections

Jaquess, Timothy K.


Over the last ten years, tremendous changes have occurred in the production methods of rolled structural-steel shapes. This study characterizes the geometric properties, tensile properties, toughness properties, and chemical composition of a set of 17 wide-flange members from four different steel mills that employ modern production methods. These material properties can be used in design and research to model the behavior of structural members. A typical stress-strain curve was calculated, based on the results from the tension testing program. Results show that the yield strength of a flange in a typical wide-flange shape is generally about 95% of the yield strength given in the mill test report.
