摘   要：针对目前预制混凝土叠合板板端伸出筋在运输及施工过程中存在的问题，设计了一种板端不出筋预制混凝土叠合板，即通过在板端纵筋位置处预留凹槽，拼接施工时采用附加钢筋通过凹槽进行连接。并利用ANSYS有限元软件，模拟分析了板端不出筋预制混凝土叠合板与整体式叠合板及密拼式叠合板的承载能力、混凝土开裂趋势以及附加钢筋的受力形式。结果表明：板端不出筋预制混凝土叠合板在力学性能方面与整体式叠合板相当，且由于附加钢筋的存在，预制底板与现浇混凝土层实现了有效传力。 Abstract: In response to the problems existing in the transportation and construction process of extending steel bars prefabricated concrete composite slabs, a new type prefabricated concrete composite slabs without extending bar at the end of the slab was designed. A groove was reserved at the longitudinal bar position at the end of the slab, and additional bars were used for connection during splicing construction. ANSYS finite element software was used to compare the bearing capacity, the cracking trend of concrete and the stress forms of additional bars of the new type composite slab with those of the integrated composite slab and the dense splicing composite slab. The results show that the mechanical properties of the new type prefabricated concrete composite slab are equivalent to those of the integral composite slab, and due to the additiona bars, the effective force transmission between the precast bottom plate and the cast-in-place concrete layer is achieved.
