摘　　要：结合全预制空心楼板与密拼叠合楼板的优势,提出一种全预制抽芯楼板,为研究此全预制楼板与结构梁连接节点在平面外静力荷载下的破坏形态、受弯性能,设计了1个全预制试件,并与1个现浇节点进行对比。通过对试件静力加载所得荷载-位移曲线及板内应力变化进行分析,表明预制节点承载力高于整体现浇节点,预制节点表现出受弯破坏,未发生叠合面的剪切破坏。Based on the advantages of the precast hollow floor and the close composite floor,a precast core-drawing floor is proposed.In order to study the failure mode and bending behavior of the joint connecting the precast floor and the structural beam under static load,a precast specimen is designed and compared with a cast-in-place joint.By analyzing the load-displacement curve and the stress variation of the specimens under static loading,it is shown that the bearing capacity of the prefabricated joints is higher than that of the cast-in-place joints,and the prefabricated joints show bending failure without shear failure of the superposed surfaces.
