在工业厂房的改建、扩建设计当中,由于结构使用功能的改变,经常会遇到对原有混凝土结构牛腿加固问题;在加固空间有限、业主对设计有特殊要求的情况下,利用柱侧牛腿和齿槽的联合设计方法能有效地提高原混凝土结构牛腿的抗剪设计承载力;在设计和施工构造措施的保证下,牛腿加固取得了成功,对以后同类问题的设计起到借鉴作用。
In the reconstruction and expansion design of industrial plants, due to the change of the function of the structure, often the problem of reinforcing the corbel of the original concrete structure is often encountered. In the case of limited reinforcement space and special design requirements of the owner, The joint design method of the leg and the tooth groove can effectively improve the shear capacity of the original concrete structure of the cowhide; under the guarantee of the design and construction measures, the reinforcement of the cowhide has been successful, and can be used to reference the design of similar problems in the future effect.
