摘　　要：提出一种由新型预应力空心板和后浇边缘构件组成的新型装配式楼盖。对试件模型进行单向反复加载试验,分析其平面内受力性能,并计算出楼盖的平面内刚度。由此讨论新型装配式楼盖是否具有替代整体现浇楼盖或带有现浇面层的普通装配式楼盖的可行性。结果表明,新型装配式楼盖的平面内受力性能良好,计算得出的平面内刚度比一般装配式楼盖的平面内刚度大6倍左右,新型装配式楼盖具有更大的平面内刚度和良好的结构整体性,新型装配式楼盖具有替代整体现浇楼盖或带有现浇面层的普通装配式楼盖的可行性。A new-type prefabricated floor composed of a new-type prestressed hollow slab and post-poured edge members was put forward. The in-plane mechanical feature and in-plane rigidity were analyzed and calculated through the unidirectional repeated loading test on specimen model. Based on the test results,it can be discussed that whether the new-type prefabricated floor can take the place of integral cast-in-situ floor or ordinary prefabricated floor with cast-in-situ surface. The results show that the in-plane mechanical feature of the new-type prefabricated floor is good and the calculated in-plane rigidity is about six times larger than ordinary prefabricated floor. The new-type prefabricated floor has larger inplane rigidity and favorable structural integrity. The new-type prefabricated floor has the possibility of taking the place of integral cast-in-situ floor or ordinary prefabricated floor with cast-in-situ surface.
