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.
