| 摘 要： | 剪力墙洞口连梁一般为小跨高比连梁,其承载力计算方法是目前尚未很好解决的问题之一.根据收集到的25个跨高比小于2.5的连梁的试验数据,用多元回归分析方法分别建立了其受弯承载力和受剪承载力计算公式.公式的预测值与试验值符合较好,可供修订混凝土规范时参考.

| Abstract: | Coupling beams in coupled shear walls are generally with small span-to-depth,and the bearing capacity calculation method of which is not yet solved suitably. Based on the experimental results of 25 coupling beam specimens gathered stirrups and span-to-depth less than 2.5, applying multiple regression analysis method,flexural and shear capacity formulae were established respectively. Predictive values by the formulae proved to agree with the experimental data. Flexural and shear capacity formulae provided could be used for revision of Code for Design of Concrete Structures of China in the future. |
