摘要
为了提高既有框架结构的抗震性能,采用隔震技术对其进行加固,提出基于性能的隔震加固设计方法。首先采用结构的层间位移角定义结构的性能目标,对非隔震结构进行静力弹塑性分析,基于静力弹塑性的分析结果,提出隔震加固方案,最后通过隔震结构的动力弹塑性时程分析,验证基于性能的隔震加固设计方法的有效性。结果表明,采用基于性能的隔震加固设计方法设计的隔震结构能够达到既定的抗震设防目标。
In order to improve seismic performance of existing frame structures（ non-isolation structures）,the isolation technology is adopted in the retrofitting work,and the performance based isolation retrofitting design method is proposed. Firstly,the inter-story drift is used to define the structure performance levels,and then Pushover analysis of the non-isolation structure is conducted. Based on the results of Pushover analysis,the isolation retrofitting scheme is put forward. Finally,the dynamic elasto-plastic time history analysis of the isolation structure is used to verify the effectiveness of the isolation retrofitting scheme based on structure performance. The results show that the isolation structure can achieve the seismic fortification goal, which is designed using performance based isolation retrofitting design method.
