基于性能的结构抗震加固理论

将基于性能的设计思想与结构加固设计方法相结合，提出了基于性能的结构加固设计理论．该理论明确了结构加固的性能目标和评价准则，清晰地展现了加固结构基于位移的设计基本过程，并将pushover静力推覆分析运用于结构加固前后抗震性能的评估．最后提出了今后的研究方向及应着重解决的问题.

Strengthening Theory of Structure Based on Performance of Seismic Design

Combining the basic idea of performance-based seismic design and design method of structure reinforcement, the theory of displacement-based design with structure reinforcement is presented in this paper. According to the theory, the performance objectives and evaluation criterion of structure reinforcement design are introduced.The concrete steps of displacement-based design with structure reinforcement are listed and the performance of original and rehabilitated structures are analyzed with pushover analysis procedure.The study direction and some settling question are showed at the end.
