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 overall analysis method of prestressed flat beam - ribbed floor structure is discussed and suggestions are put forward. The influence of prestress and flat beam width on floor stiffness is analyzed by finite element method. The results show that the prestressed tensioning construction phase Is often the most unfavorable load conditions, and the effect of flat beam width on floor stiffness is small.
