矩形開口を有する鋼製H形断面材の終局耐力(I-2) : 無補強の場合

抄録

This report (I-2) is the continuation of the previous report (I-1), and it was intended to clarify the mechanical properties of a steel H-section with an unreinforced rectangular hole. As for the experiment, the repeated loading experiment supposing an earthquake load and the monotonous loading experiment to let a shearing force excel in the sections with openings were carried out. From these experimental results, the strength, deformability, hysteresis characteristics and so on were determined, and a comparison with the strength equation derived in the previous report was attempted to examin its propriety.
