X形配筋を施した鉄筋コンクリート構造の弾塑性性状に関する基礎的研究 (その3)

Abstract

To clarify the effect of the diagonal reinforcement on the failure modes, useful strength, deformation capacity, and hysteretic characteristic of diagonally reinforced columns, total ofeight half-scale columns are tested under high intensity cyclic reversed loading. Variablechosen for experiments are diagonal reinforcement ratio β (0, 0.2, 0.4 and 0.6) and shearreinforcement ratio ρw (0.20% and 0.42%). The deformation capacity and energy dissipa-tion of columns increases with increase of the diagonal reinforcement ratio β.
