［摘要］通过对现浇钢筋混凝土短柱与预制钢筋混凝土短柱进行低周反复加载抗震性能试验，研究了预留水平连接缝的形式对采用套筒灌浆连接纵筋的预制钢筋混凝土短柱抗震性能的影响。研究结果表明：套筒灌浆连接纵筋的搭接方式是一种可靠的连接方式；预留水平连接缝的不同形式对试件极限承载力的影响不大，且与现浇钢筋混凝土短柱有类似的抗震性能；除光滑水平连接缝套筒灌浆的短柱外，其余短柱试件均有较好的塑性变形能力。［关键词］预制钢筋混凝土短柱; 水平连接缝; 套筒灌浆连接; 抗震性能; 抗剪性能中图分类号：TU375.3 文献标识码：A 文章编号：1002-848X(2015)15-0081-06
Experimental study on seismic behavior of precast reinforced concrete short columns with grouted sleeves connecting longitudinal reinforcementsZhang Yiping1, Feng Bo2, Xiong Feng2, Zhang Chuan3, Wang Lei3, Kui Ping1，Zhang Chunlei1, Niu Jinhu1（1 Sichuan Provincial Architectural Design and Research Institute, Chengdu 610000, China; 2 College of Architecture & Environment, Sichuan University, Chengdu 610065, China; 3 School of Civil Engineering, Chongqing University, Chongqing 400045, China)Abstract:Reversed cyclic loading tests on cast-in-situ reinforced concrete short columns and precast reinforced concrete short columns were carried out to investigate the effect of detailing of the horizontal joint on seismic behavior of such precast reinforced concrete short columns with grouted sleeves connecting longitudinal reinforcements. The results show that grouted sleeves are reliable in connecting longitudinal reinforcements. Detailing of the horizontal joints has little effect on ultimate capacity of the precast reinforced concrete short columns, and they have very similar seismic behavior to the cast-in-situ reinforced concrete short columns. Except the precast reinforced concrete columns with smoothed horizontal joint, the rest specimens have expected plastic deformation capacity.Keywords:precast reinforced concrete short column; horizontal joint; grouted sleeve; seismic behavior; shear behavior
