［摘要］对预制板带接缝的混凝土叠合楼板进行了足尺试验，研究了叠合板的受力性能，包括破坏机理、承载力、刚度、裂缝分布、叠合面抗剪性能等。并对比研究了钢筋桁架对叠合板的作用、拼接缝对叠合板的影响。通过与理论分析进行对比，提出了计算假定和计算方法，为带接缝的装配式叠合楼板的设计提供参考。［关键词］装配式混凝土结构; 叠合楼板; 足尺试验; 钢筋桁架中图分类号：TU398 文献标识码：A 文章编号：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
