摘要: 在全预制钢筋混凝土框架梁柱干式企口连接中,钢筋混凝土缺口梁是重要的传力构件。应用拉压杆模型和剪力摩擦等理论对刚性企口连接中缺口梁的各种破坏形式进行分析,推导出相应的承载力公式,然后应用有限元分析软件ANSYS对该连接中钢筋混凝土缺口梁进行有限元分析,并对承载力公式进行了验证。

Abstract: The dapped-end beams are the vital supporting members in the dry rigid dapped -end connections in full precastconcrete frame. The dapped-end beams in all destroyed forms are analyzedwith stru-t and-tie modelmethod and shear-frictiontheory, etc, and corresponding design formulas are deduced. Some design advices are put forward. By the analyses of thedapped -end beams with finite element software ANSYS, the design formula is validated. This research has valuableinformation on designing analogical dapped -end -beams.
