高强螺旋肋钢筋预应力混凝土空心叠合板与底板开裂弯矩相关关系研究

Study of correlation of cracking moment between prestressed concrete hollow laminated slabs and prestressed concrete bottom slabs with high tensile sprial ribbed stell bars

通过计算分析与试验研究,分析了螺旋肋钢筋预应力混凝土叠合空心板与底板开裂弯矩相关关系,提出二者相关关系模式与实用计算方法,为该类空心叠合板设计与结构性能检验提供了新的方法与计算手段,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。

Through theoretical analysis and experimental investigation on correlation of cracking moment of prestressed concrete laminated hollow slabs and corresponding prestressed concrete hollow bottom slabs with spiral fibbed steel bars in this paper, the correlation model and calculation formulae of cracking moment between the prestressed concrete laminated slabs and corresponding bottom slabs are proposed, which can provide a new method and means of calculation for design and performance test of structure for this kind of structural members. Also these results would be used for the reference in the relevant norms and universal standards of Atlas preparation and applied in preeast production,construction and inspection departments.
