为解决现有预应力混凝土叠合板存在的问题,提出由预制预应力带肋底板(肋上预留孔洞)与后浇混凝土叠合形成的双向楼板。针对该叠合板独特的结构形式以及预制底板与后浇混凝土的整体作用,提出该楼板双向受力性能。借助有限元程序ANSYS10.0进行楼板模拟,通过大量计算研究该楼板双向受力效应的存在及变化规律,为深入开展该楼板结构性能的研究提供依据。
In order to solve the existing problems of existing prestressed concrete plywood, a two-way floor is proposed, which is formed by prefabricated prestressed ribbed floor (reserved hole on the rib) and post-poured concrete. According to the unique structure of the plywood and the overall effect of prefabricated slab and post-cast concrete, the bi-directional stress performance of the slab is proposed. The finite element program ANSYS10.0 is used to simulate the floor, and the existence and variation regularity of the two-way stress effect of the floor are studied through a large number of calculations to provide the basis for further study on the performance of the floor structure.
