摘要: 在全预钢筋制混凝土框架梁柱干式暗牛腿节点中,钢筋混凝土暗牛腿是重要的竖向传力构件。应用拉压杆模型方法和剪力摩擦理论对暗牛腿进行分析,推导出其承载力公式,并提出相应的设计建议。然后应用有限元分析软件ANSYS对该连接中钢筋混凝土暗牛腿进行了有限元分析,并对承载力公式进行了验证。提出的设计方法可以为此类暗牛腿的设计提供相应参考。

Abstract: The hidden corbel is the vital supporting member in the dry beam-column connections in full precast concrete frame. The hidden corbel is analyzed with strut2and2tie model method and shear2friction theory, and corresponding design formulas are deduced. Some design advices are put forward. By the analyses of the hidden corbels with finite element software ANSYS, the design formula put forward in the paper is validated. This research has valuable information on designing analogical hidden corbels.
