抗剪柱的抗剪性能试验研究
|
摘要
对三种不同构造形式的抗剪柱进行了试验研究，试验结果表明：抗剪柱是保证上、下层板共同工作的关键；预制抗剪柱与整浇抗剪柱比，抗剪刚度及抗剪承载力降低较多；目前预应力空腹楼盖结构体系的抗剪柱与下层板连接宜优先采用抗剪柱与下层板整浇的施工方式；为了验算的目的，文中给出了预制抗剪柱和整浇抗剪柱的本构模型。
In this paper, three kinds of shear columns with different construction forms were tested. The results showed that: the shear column is the mostly important factor to keep up and down the layer slabs work together. In comparison with the integrally cast column, the precast one possesses much weaker shear rigid and shear capacity. The shear columns used at present in the prestressed floor structure should be the integrally cast ones. In the paper, the constitutive models of both integrally cast and precast shear columns are provided for calculation.
