Cyclic Behavior of High Strength Steel H-Shaped Beam

Abstract:

This study is intended to show possibility of using high strength steel for H-shaped beams with large depth-thickness ratio in the elastic range by conducting loading tests. Test specimens are manufactured with high strength steel of over 700N/mm2 yield stress. Elastic behaviors of such beams under cyclic loading are mainly concerned. In addition, the redundancy and the stability of these beams in plastic range are investigated. It is shown that these beams are useful as seismic design beams although the depth-thickness ratio of H-shaped beams is larger than the limit of current standards in Japan. Also, by referring to a recent study, a new limit value of plate slenderness ratio (depth-thickness ratio of web plate and width-thickness ratio of flange plate) is proposed.
