摘   要：使用ANSYS有限元软件建立了20种带不同孔洞缺陷的钢筋混凝土框架柱有限元模型，并对其进行了模拟低周反复加载，分析了孔洞缺陷对框架柱荷载-位移滞回曲线、骨架曲线、位移延性比、塑性滞回耗能、刚度退化及强度退化等抗震性能指标的影响规律。结果表明，孔洞缺陷可以改变框架柱的破坏形式，降低框架柱的极限承载能力、位移延性比和塑性滞回耗能能力，加剧了框架柱的刚度退化和强度退化，给框架柱的抗震带来较为不利的影响，贯穿孔洞造成的影响最大。

Abstract: The 20 reinforced concrete frame column finite element modes with different hole defect were established based on ANSYS. The simulative repeated low cycle loading tests were carried to research on the influence of hole defect to the column seismic performance targets, including load-displacement hysteresis curve, skeleton curve, displacement ductility ratio, hysteresis energy, stiffness and strength degradation. It’s found that the hole defect would change failure mode of frame column, reduce the ultimate bearing capacity, displacement ductility ratio and hysteretic energy and aggravate stiffness and strength degradation. Through hole has the worst impact on the frame column.
