摘要：通过对核心区应用X形配筋增强的高强钢筋异形柱边节点和同等条件下未被增强的高强钢筋异形柱边节点进行拟静力试验研究，对比分析异形柱边节点的破坏特征、滞回曲线、承截能力、位移及延性、剧度退化、耗能能力等抗震性能指标。研究结果表明，配置HRB500高强钢筋异形柱边节点比配置600MPa级的边节点承载能低，但滞回性能好，变形能力强，刚度退化推迟，耗能能力强；在核心区加入X形配筋，均可以改善高强钢筋异形柱边节点的破坏特征，使边节点抗剪能力、变形能力、耗能能力增强，度退化推，提高异形柱边节点抗震性能，配置HRB500高强钢筋的试

Abstract:The exterior joints of specially shaped columns with high-strength reinforcement, and with or without X-shaped reinforcement were tested under low cyclic loading. The damage characteristic hysteretic curve, bearing capacity, displacement, ductility, stiffness degradation and energy dissipation capacity were compared. The results showed that for the exterior joints of specially shaped columns, the bearing capacity of the HRB5oo joint was lower, but the hysteretic behavior, deformability, energy dissipation capacity were increased, the stiffness degradation was postponed. When X-shaped high-strength reinforcement added to the joints, the failure characteristics of the joint was improved, the stiffness degradation was postponed, the deformability, shear capability and energy dissipation capacity were increased, the seismic behavior of specially shaped column joints was improved significantly,and the seismic
