摘要
通过四块足尺寸对边简支双向预应力砼板的抗弯试验,结合其非线性有限元计算分析,得出了双向预应力交互影响的概念及其计算式,并初步认识到双向预应力板较单向预应力板的抗裂有较大的提高。
This paper shows the concepts of the interactive effects of the prestress in dual directions and calculation formula which are obtained by the bent - resistance test result of four pieces of full scale simple prestressed reinforced concrete slab at both sides of dual directions combining the unlinear limited element calculation and shows the cracking resistance of the prestressed slab of dual directions is rather higher than that of single direction.
