    摘要:

    对4个高强钢筋高韧性混凝土框架中节点进行低周往复加载试验,对比不同范围采用高韧性混凝土进行增强的节点与同条件下未增强的节点的承载能力、变形能力、滞回特性、刚度退化、耗能能力等抗震性能指标。结果表明,在节点中采用高韧性混凝土进行增强,可以改善节点破坏形态,提高试件的承载能力和变形能力,提高构件的抗震性能,由节点核心区延伸至1倍有效梁高范围内采用高韧性混凝土进行增强的节点对变形性能、刚度退化、延性和耗能能力增强效果最佳。

    Abstract:

    Four interior joints with high-strength reinforcement and high-toughness concrete were investigated with low cyclic loading. Joints under different rage of high-toughness concrete and those without were compared in terms of seismic behavior indexes such as bearing capacity, deformability, hysteretic characteristics, stiffness degradation and energy dissipation capacity. The failure patterns, bearing capacity, deformability and seismic behavior of those frame interior joints with high-toughness concrete were improved, and the offective rarge of high-toughness concrete was from core area of joint to the one time adjacent height of beam to improve deformability and stiffness degradation.
