摘要
为了抵抗强震作用,必须使结构物具有良好的延性。本研究的主要目的在于调查采用了圆形螺旋箍筋的钢筋混凝土延性柱在大变形领域的多次重复加荷条件下的力学性能。本文介绍了关于该柱的实验概要,并对该柱的破坏过程、剪力—位移关系滞回曲线的特性、塑性铰区域内的变形特性等实验结果作了若干讨论。
To survive a severe earthquake a structure should be designed whose members possess characteristics of excellent ductility.The object of this study is to investigate the mechanical properties of reinforced concrete circular columns with circular spiral confining reinforcement by the experimental work,in which the columns were subjected to high intensity reversed cyclic lateral load and constant axial load. In this paper,the experimental work and a part of experimental results are described,which include the failure process,the deflec- tion behavior,and the deformation characteristics in the equivalent plastic hinge zone.
