预应力混凝土叠合空心板与底板开裂弯矩相关性研究

Correlation and Calculation Model of Cracking Moment Between Prestressed Hollow Slab and Prestressed Concrete Laminated Hollow Slabs

通过理论分析与试验研究,分析了预应力混凝土叠合空心板与底板开裂弯矩相关性特征,提出了二者相关性模式与相应的计算方法,为预应力混凝土叠合空心板与底板结构性能检验提供了新的检验方法与计算手段,可供有关规范及标准图集的编制和设计、生产、检验部门参考试用。

The correlation of cracking moment between prestressed hollow slabs and laminated hollow slabs are analysed. The calculation models and equations about the correlation are also suggested as reference for prestressed hollow slabs and laminated hollow slabs in design, production, construction and working out of general standard gallery.
