| 摘 要： | 文章以张拉体外预应力加固的钢筋混凝土双向板为研究对象,说明了在双向板中利用体外预应力加固技术的构造特点,推导出了几种加固工况下四边简支双向板挠度变形的计算公式。研究与计算结果表明,张拉体外预应力可以减少双向板的挠度变形,降低双向板的内力,加固的作用效果是显而易见的。

| Abstract: | This paper presents the RC two-way slabs strengthened by external prestressing technique.The construction properties of external prestressing in two-way slabs are illustrated.Some calculating formulas are also deduced for simply supported two-way slabs.Studies indicate that the two-way slab' s deflection and internal force can be reduced by using the external prestressing technique,and its strengthening mechanism is obvious. |
