Abstract

An experimental investigation to study steel beams with eccentric web openings is presented. Four steel beams, with eccentric web openings; one beam without openings and two with centric openings were tested. IPE200 Profile was used for the tested beams. The opening sizes were fixed and have depth equal to 40 percent of the steel beam depth and a length equal to one and half the opening depth. The opening locations were varied to investigate the structural behavior of these types of beams with openings. Web openings generally reduce the strength of steel beams. Beams under pure moment fail by yielding in the steel below the neutral axis. Beams under high shear-low moment straining actions fail by the formation of plastic hinges at under high shear-low moment straining actions fail by the formation of plastic hinges at the corners of the opening followed by yielding in the steel beam. The main parameters in this study were the failure loads, the deflections at various locations on the span of the beam, the strains in longitudinal and transverse directions at the corners of the opening and the modes of failure. The main objective of the openings relative to the center line of the beam as well as relative to the support of the support of the beam.
