【摘要】 通过理论与试验研究,分析了预应力混凝土底板(实心、空心)与叠合板开裂弯矩相关性、抗弯极限承载力相关性,提出了二者相关关系模式与相应的计算方法,为叠合板与底板结构性能检验提供了新的检验方法与计算手段,弥补了叠合板与底板结构性能现有检验方法的不足,可供有关规范及通用标准图集编制和生产、检验部门参考试用。更多还原

【Abstract】 In this paper,through the theory analysis of the relationship in cracking moment and ultimate moment between prestressed thin slabs/hollow slabs and prestressed single supported and conitunous laminated slabs and the test researches on the relationship in cracking moment and ultimate moment between thin slabs/hollow slabs and laminated slabs,the calculation models and formulae about the relationship in cracking moment and ultimate moment between the thin slabs/hollow slabs and laminated slabs are given and new completed calculation models and methods which are also suggested as reference for prestressed thin slabs/hollow slabs and laminated slabs in production,construction and working out of general standard gallery are put forward.更多还原
