带耗能腋撑型钢混凝土梁转换结构是一种新型的转换结构,受力状态和抗震性能有别于普通的耗能减震结构,设计过程缺乏理论指导。因此,该文在建立该种新型结构简化计算模型的基础上,通过理论分析方法推导了结构各控制截面的内力计算公式,建立了一套该种结构基于“强柱弱梁”、“强剪弱弯”和“强节点弱构件”等延性设计思想的设计方法。设计实例分析证明,根据该文方法设计的带耗能腋撑转换结构,相比普通结构转换层处的刚度突变得到了缓解而且结构的延性得到了提高。该文提出的方法可为该种新型转换结构的设计提供理论依据。
The transition structure with energy dissipation axillary SRC is a new type of conversion structure. The stress state and the seismic performance are different from the ordinary energy dissipation structure. The design process lacks theoretical guidance. Therefore, on the basis of establishing this kind of new structure simplified calculation model, the paper deduces the internal force calculation formula of each control section of the structure through the theoretical analysis method, and establishes a set of such structure based on “strong column weak beam The design method of ductility design such as ”strong shear weak bend“ and ”strong joint weak member". The design example shows that according to this method, the sudden change of stiffness is alleviated and the ductility of the structure is improved compared with that of the ordinary structural transfer layer. The method proposed in this paper can provide a theoretical basis for the design of the new conversion structure.
