ABSTRACT
This paper presents the details of full-scale experiments on short beam members fabricated from high strength steels (HSS) with a yield stress of 690 MPa. The test specimens include I-shaped beams fabricated from Bisplate80 steels (nominal fy = 690 MPa) with a combination of various slenderness ratios of plate elements in the section. The slenderness of the component plates was chosen in the range near the yield slenderness limit, beyond which the flexural strength of the short beams was reduced by the local buckling effects. The purpose of the experimental study was to investigate the flexural behavior and strength of high strength steel beam members subject to local buckling effects and compare with predictions from the current steel design standards. This paper describes the details of the full scale experiments of HSS beams and the results, and their comparison with current steel design code predictions. It also includes the results of residual stress tests undertaken for such HSS beams.
