THEORETICAL STUDY ON TWO-WAY EFFECTS OF CONCRETE COMPOSITE SLAB WITH PRECAST PRESTRESSED RIBBED PANEL
-
摘要: 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。Abstract: New type of two-way concrete composite slab with precast prestressed ribbed panel(including preparative holes in the rib) is put forward to solve the problems in traditional prestressed concrete composite floor.Based on the particular structural feature and integral action between precast ribbed panel and combined interface concrete two-way effects are proposed.The finite element analysis by ANSYS10.0 program is conducted.The existence and the variation tendency of two-way effects under the loads in different conditions are researched by large numbers of models,which provides a basis for the further investigation on property of the floor structure.
