［摘要］對(duì)預(yù)制板帶接縫的混凝土疊合樓板進(jìn)行了足尺試驗(yàn)，研究了疊合板的受力性能，包括破壞機(jī)理、承載力、剛度、裂縫分布、疊合面抗剪性能等。并對(duì)比研究了鋼筋桁架對(duì)疊合板的作用、拼接縫對(duì)疊合板的影響。通過(guò)與理論分析進(jìn)行對(duì)比，提出了計(jì)算假定和計(jì)算方法，為帶接縫的裝配式疊合樓板的設(shè)計(jì)提供參考。［關(guān)鍵詞］裝配式混凝土結(jié)構(gòu); 疊合樓板; 足尺試驗(yàn); 鋼筋桁架中圖分類號(hào)：TU398 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2016)10-0056-05
Experimental study on full-scale superimposed concrete slab with jointsYan Feng1, Gao Jie1, Tian Chunyu1, Hao Wei1, Tan Yuang2（1 CABRTECH Co., Ltd., Beijing 100013, China; 2 Vanke Co., Ltd., Shenzhen 518083, China)Abstract: Full-scale test was carried out on superimposed concrete slab with joints in precast slabs to study the mechanical performance of superimposed slab. The properties were studied including failure mode, bearing capacity, stiffness, crack distribution and shear capacity of superimposed surface. The influences of steel bar truss and joints on superimposed slab were compared and investigated. By comparing with the theoretical analysis, the calculation assumptions and calculation methods were put forward, providing a reference for the design of precast superimposed slab with joints.Keywords: precast concrete structure; superimposed slab; full-scale test; steel bar truss
