| 摘 要： | 钢筋混凝土剪力墙结构通过设置可更换连梁，在地震作用下集中损伤，保护主体结构不受或只受微小破坏，震后更换损伤构件即可恢复结构功能。参照现行规范和已有试验分析结果，在普通钢筋混凝土结构设计基础上，提出带有可更换连梁的钢筋混凝土结构实用设计方法，设定性能目标，总结设计流程。采用提出的设计方法对1个50层钢筋混凝土结构进行设计，并采用大型有限元分析软件ABAQUS建立数值模型，验证结构性能目标和提出的设计方法。结果表明:按该方法设计的带有可更换连梁的钢筋混凝土结构能满足所设定的性能目标，设计方法合理实用，为该新型结构的工程应用提供了参考。

| Abstract: | Reinforced concrete (RC) structure with replaceable coupling beams is designed to concentrate damage in the replaceable device, and the main structure is thus protected and the damaged device could be replaced after earthquakes. Referred to the current design codes and existed experimental results, this paper proposed a design method for the RC structure with the replaceable coupling beam, based on the traditional RC structures. The performance target of the new structure was proposed and the design flow path was shown. A 50-story reinforced concrete structure with replaceable coupling beams was designed following the design methods. Finite element analysis software ABAQUS was used to verify the performance objectives and rationality of the proposed design method. Results show that the designed RC structure with replaceable coupling beams could satisfy the performance objectives and the design method is proved to be a rational one, providing a reference of engineering application of this innovative structure. |
