二方向繰返し力を受けるRC柱の載荷履歴が変形性状に及ぼす影響に関する研究

抄録

In the present paper, the bi-axial cyclic loading test of RC columns with the different intervals of lateral hoop tie has been performed under the different loading histories. By comparing the results obtained from the uniaxial cyclic loading tests which had been so far performed by the authors, the influence of loading direction and interval of lateral hoop tie on the deformational performance, such as the lateral strength and ductility of RC columns, and on the buckling behavior of re-bar has been examined in details. Furthermore, the loading-path dependency has been discussed with the comparison of the buckling behavior of re-bars and damage inside the RC column induced by the different loading paths up to the same displacement level.
