现浇空心楼盖抗剪性研究

Analysis of shear capacity for in-situ hollow floor

通过对《混凝土结构设计规范》、《现浇混凝土空心楼盖结构技术规程》和实验结论的研究,分析现浇空心楼板的结构特点,从而得出了现浇空心楼盖抗剪设计的必要性。在空心楼盖的抗剪验算时,要考虑到横肋与顺肋板之间的区别和箍筋在其中起到的作用,并给出了计算公式。

It is necessary to carry out shear design for in - situ hollow floor, which is concluded basing on the researches on ＂the code for design of concrete structures＂, ＂technical specification for cast - in - situ concrete hollow floor structure＂ , experimental results and analysis of the structure of in - situ hollow floor, we should consider the difference between Cross rib and rib , and the importance of the stirrup . At last we provide the calculation formula of shear.
