Inelasatic behavior of h-shaped steel beam-columns subjected to two-dimensional horizontal monotonic load: Study on inelastic behavior of H-shaped steel beam-columns subjected to two-dimensional horizontal load Part 1

Abstract

In this study, an inelastic biaxial bending experiment in which a horizontal force is loaded in a direction at a certain angle to the principal axis of the section was carried out for H-shaped steel beam-columns each with a relatively small slendemess ratio having an inelastic energy absorption capacity. As the result of studies on the elasto-plastic behavior as well as on the analysis results, it was made clear that the maximum strength ratio (the ratio of the maximum moment to the full plastic moment), the ductility factor and the energy absorption capacity decrease with the change in the loading angle from 0° (strong axis bending load) to 90° (weak axis bending load).
