［摘要］基于我國規(guī)范標準的兩級鑒定方法及以“小震不壞”為單一目標的傳統(tǒng)抗震加固為基礎，總結得到基于性能的減震加固、隔震加固方法，給出既有建筑結構抗震性能評估方法及相關可量化指標、設計流程、關鍵技術等。經(jīng)過分析得出，基于性能的減震加固、隔震加固技術相比傳統(tǒng)抗震加固技術可實現(xiàn)更高的性能目標且具有比較明顯的經(jīng)濟優(yōu)勢，在既有醫(yī)療建筑、防災減災建筑、學校等生命線工程的抗震性能提升中有著廣泛應用前景。
［關鍵詞］既有建筑；混凝土結構；減震加固；隔震加固；抗震性能評估

Abstract:Based on the two grade appraisal methods and the traditional seismic strengthening with “small earthquake is not destroyed” as single objective according to Chinese codes and standards, the methods of energy dissipation reinforcement and seismic isolation reinforcement based on performance were summarized, the assessment methods of seismic performance of existing buildings and the relevant quantifiable indexes, design procedures, key technologies and so on were given. Evidence from numerical analysis makes it clear that the performance-based technologies of energy dissipation reinforcement and seismic isolation reinforcement which can achieve higher performance goals and has apparent economic advantages compared with the traditional seismic reinforcement technology. There are broad application prospect in the seismic performance improvement of lifeline projects, such as existing medical buildings, disaster prevention and reduction buildings,schools and so on.
Keywords:existing building; concrete structure; energy dissipation reinforcement; seismic isolation reinforcement; seismic performance assessment
