基于拉压杆模型的梁托牛腿设计分析方法

摘要:

借鉴国外规范,构建了梁托牛腿的拉压杆模型,对梁托牛腿进行受力分析,明确了设计过程中需重点关注验算的拉杆。通过试验验证,表明该拉压杆模型方法可以较为便捷、可靠、有效地预测梁托牛腿的极限承载力,为梁托牛腿的设计提供参考。

Abstract:

According to foreign codes, a strut-and-tie model of beam ledge is constructed. The flow of forces in beam ledge are analyzed by the strut-and-tie model, and the ties that need to be paid attention to in the design process are defined. The results of the strut-and-tie model are compatible with the experimental results. The strut-and-tie model can predict the ultimate bearing capacity of beam bracket conveniently, reliably and effectively, and provide a reference for the design of beam ledge.
