摘　　要：针对预应力扁梁——密肋楼盖结构的整体分析方法进行了讨论并提出建议,利用有限元方法分析了预应力和扁梁宽度对楼板刚度的影响,其结果表明预应力张拉施工阶段往往是最不利的荷载工况,而扁梁宽度对楼板刚度的影响较小。The author discusses the computing method of internal forces in the prestressed concrete flat beam -ribbed floor system. Accordingly, some practical recommendations are proposed. In addition, finite analysis method is used to explore the effect of prestrssing and flat beam width on the stiffness of floor. The results indicate that the prestress-ing phrase is usually the most unfavorable phrase and the flat beam width has little effect on the stiffness of floor.
