某既有混凝土框架结构抗震鉴定及加固设计研究

摘要

结合某既有钢筋混凝土框架结构抗震加固改造设计实例,在对原结构分析验算的基础上,对比分析了框架+阻尼器结构体系和框架-剪力墙结构体系,介绍了带阻尼器结构的设计和计算方法.通过对计算结果的分析,比较了两种结构体系的优缺点,最后介绍了新增剪力墙连接做法.可为类似项目的结构加固设计提供一定的参考.%Combined with a existing engineering design illustration with seismic reinforcement and reconstitution, based on the analysis and checking calculation of the original structure, frame + damper structure and frame-shearwall structure are analyzed, the design and calculation method of damper are introduced. Through analysis of the results, the advantages and disadvantages of the two types are compared. Finally the connection method of newly-added walls is presented. This project can provide a reference for the retrofit design of similar structure.
