摘要:

对预应力扁梁-密肋楼盖体系在预应力张拉过程中楼板的变形、预应力混凝土梁的变形和应变进行了现场测试和分析，运用有限元程序对结构的预应力施工过程进行了模拟分析，讨论了预应力扁梁-密肋楼盖体系的预应力效应的建立，指出预应力效应的建立受到楼板平面内刚度的影响。

Abstract:

During the pre - stressing of the unbonded prestressed concrete wide flat beam - waffle slab system, the displacements and strains of slab and the prestressed concrete beams were site - measured and the results were analyzed. The prestressing construction was simulated by finite element program. The prestressing efficiency of the unbonded prestressed concrete wide flat beam - waffle slab system was discussed. It indicates that the prestressing efficiency was affected by the in -plane stiffness of slab.
