装配式整体预应力板柱结构楼板的简化计算

Simplified Calculation Method of Plate for Slab-Column Structure Assembled by Monolithic Prestressing

装配式板柱结构的空心楼盖,是由预制的空心拼板通过预应力钢筋整体张拉而形成的整体钢筋混凝土楼盖,它不同于现浇的无梁空心楼盖。文中提出了装配式整体预应力板柱结构整体结构空间分析时楼板的截面惯性矩的简化计算方法,该计算方法采用加权平均法,使空心楼盖的各部分都充分参与了计算,计算结果更接近空心楼盖的真实值,并通过工程实例的对比计算证明该简化计算方法的可行性和实用性。

Hollow floor of slab-column structure assembled different from cast-in - situ girderless hollow floor is a type of integral reinforced concrete floor which is consolidated by cored slab with stretched prestressed tendon. The simplified calculation method of sectional inertia moment for plate is proposed when analyze integral structure space of slab-column structure assembled by monolithic prestressing. It adopts weighted average method which makes all parts of hollow floor calculated and the results approach truth. The feasibility and practicability are proved through the contrast calculation of actual engineering.
