［摘要］通過(guò)對(duì)現(xiàn)澆鋼筋混凝土短柱與預(yù)制鋼筋混凝土短柱進(jìn)行低周反復(fù)加載抗震性能試驗(yàn)，研究了預(yù)留水平連接縫的形式對(duì)采用套筒灌漿連接縱筋的預(yù)制鋼筋混凝土短柱抗震性能的影響。研究結(jié)果表明：套筒灌漿連接縱筋的搭接方式是一種可靠的連接方式；預(yù)留水平連接縫的不同形式對(duì)試件極限承載力的影響不大，且與現(xiàn)澆鋼筋混凝土短柱有類似的抗震性能；除光滑水平連接縫套筒灌漿的短柱外，其余短柱試件均有較好的塑性變形能力。［關(guān)鍵詞］預(yù)制鋼筋混凝土短柱; 水平連接縫; 套筒灌漿連接; 抗震性能; 抗剪性能中圖分類號(hào)：TU375.3 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：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
