摘要
本文以纵向受拉钢筋配筋率以及纵向受拉钢筋在节点内不同搭接形式为主要变量，通过6榀足尺钢筋混凝土叠合框架时负弯矩作用下的顶层角节点的静力性能进行了试验研究，并对节点的受力性能进行了二维非线性有限元模拟分析，最后根据实验及分析结果提出了支座汉钢筋的锚固构造．
In order to investigate the behaviour of the composite frame corner joints subjected to closing loads, experiments on 6 fullscale reinforced concrete composite frames were carried out in this paper. The primary variables were the steel ratio and the splicing form. Then a nonlinear finite elements analysis of the frame corner joints was performed. Finally, based on the experimental results and their analysis, the anchorage construction of the support was presented.
