本文介绍了一种可拆卸和可拆卸的新型复合楼板系统的实验研究。在该系统中，组合板，形成与压型金属盖板，连接到一个钢梁通过可拆卸的剪切连接器。一个全尺寸的可拆卸复合地板系统（DCFS）进行了测试，以极限承载能力，并与一个类似的不可拆卸的复合地板系统样本使用传统的焊接头螺栓连接器进行了比较。试验结果和观察表明，两种组合楼板系统的结构性能和承载能力非常相似。然而，带有可拆卸剪力连接件的组合楼盖系统可以在测试后进行拆除，并且组合板可以很容易地从钢梁上拆卸下来。本文的比较和分析表明，目前欧洲规范4中关于焊接抗剪节点的简单设计方法可以用来评估节点的极限承载力。
An experimental study on an innovative composite floor system that can be demounted and deconstructed is described. In this system, the composite slab, formed with profiled metal decking, was connected to a steel beam by way of demountable shear connectors. A full-scale demountable composite floor system (DCFS) was tested to ultimate load-bearing capacity and compared with a similar non-demountable composite floor system specimen using conventional welded headed stud connectors. The experimental results and observations showed that the structural behaviour and load-bearing capacity of both composite floor systems were very similar. However, the composite floor system with demountable shear connectors could be deconstructed after testing and the composite slab could be easily detached from the steel beam. The comparison and analysis presented in this paper indicate that the simple design methods currently provided in Eurocode 4 for welded shear connections could be used to assess the ultimate moment capaci...
