摘　　要：以可拆装多层停车库示范工程的钢-混凝土组合楼板为研究对象,对可拆装钢-混凝土组合楼板承载力及连接性能进行试验研究,结果表明:通过砝码施加车库可变荷载的方案是可行的,在设计荷载下,组合楼板各构件安全可靠,组合楼板与钢梁的连接可靠,得到了组合楼板破坏失效模式为压型钢板与钢框架界面发生滑移。研究成果可为可拆装钢-混凝土组合楼板的设计、应用推广提供试验数据支持。This paper was focused on the steel-concrete composite slabs which was used in the demountable multistorey garage project,and the bearing capacity and connection performance of steel-concrete composite slabs were investigated.The results showed that the scheme of variable loading through the weights was feasible,every component of composite slabs was safety and reliability under design loads,the connections between composite slabs and steel beams was reliable,and the slip failure was the failure mode of composite slabs which was observed in the interface between profiled steel sheets and steel frames.These results provided the test foundation for the design and application of the demountable steel-concrete composite slabs.
