Bending-shear interaction in short coupling steel beams with reduced beam section

This report presents a parametric study conducted using an experimentally calibrated numerical model, performed at the CEMSIG Research Centre (http://www.ct.upt.ro/en/centre/cemsig) at the Politehnica University of Timisoara. The study observes and characterizes the plastic mechanism of short steel beams with reduced beam sections (RBS) applied in moment-resisting frames. A simplified and reliable alternative allowing the use of beam finite element analysis (FEA) for bending-shear interactions is proposed.
