摘要
对预应力混凝土空心板最小配筋率的变化进行了分析和讨论,通过对计算结果的分析处理,对预应力空心板的设计提出几点建议,证明了所得优化系数有较好的应用价值。
In the case of under reinforced concrete, brittle tension failure often occurs in concrete structure, which steel fracture. Especially the case occurs more easily because of the exist of the initial prestress. By the discussing and analysis, the paper gets the valuable optimization coefficients and gives us some advice for designing of prestress concrete hollow salb.
