装配式核心钢管混凝土柱抗震性能试验研究

Abstract:装配式核心钢管混凝土(PCSTRC)柱可用于混合结构中的柱-柱快速拼装。为研究其抗震性能,设计并进行了5个PCSTRC柱、2个现浇CSTRC柱以及1个钢筋混凝土柱的足尺拟静力加载试验,结合数字图像相关(DIC)技术对柱加载全过程的变形进行了量测。分析了PCSTRC柱与现浇柱在破坏形态、承载力、滞回耗能和变形性能等方面的差异,以及轴压比、配钢率和装配位置对PCSTRC柱抗震性能的影响。结果表明:PCSTRC柱均发生预期的弯曲破坏模式,滞回曲线饱满,承载力、刚度和耗能能力与现浇柱接近,极限位移角与延性略有增加,钢筋套筒可有效传递钢筋应力,核心钢管增强了竖向连接的可靠性;PCSTRC柱与现浇柱的曲率分布差异主要集中在钢筋套筒及套筒下端拼接区域,在总水平位移中由滑移机制所产生的刚体转动变形占比增大。
