摘　　要：通过对加固改造中旧柱新梁节点设计方案的详细讨论 ,推荐了新增牛腿这种简单可靠的方案。在新增牛腿的设计时 ,提出了应同时按桁架机理和剪摩擦机理进行牛腿的配筋计算。最后给出了牛腿的配筋形式以及牛腿和梁之间的连接构造。The design scheme of the corbel between the old column and the new beam in the strengthening projects is discussed in detail,and a simple and reliable scheme that uses the bracket is recommended. In the design of the bracket,both the truss mechanism and the shear friction mechanism should be used to calculate the reinforcement of the bracket simultaneously. Finally the reinforcement forms of the bracket and the connecting construction between the bracket and the beam are proposed.
