［摘要］以目前在建的江西省博物館超限高層建筑為例，結(jié)合基于性能的抗震設(shè)計(jì)理論和方法，根據(jù)建筑物的重要性合理確定結(jié)構(gòu)的抗震性能目標(biāo)及構(gòu)件在各設(shè)防地震烈度下的性能水準(zhǔn)。使用PKPM，MIDAS,YJK軟件進(jìn)行多遇地震作用下彈性計(jì)算分析、設(shè)防地震作用下彈性和不屈服分析，采用SAUSAGE軟件進(jìn)行罕遇地震彈塑性分析。通過(guò)彈塑性時(shí)程分析方法驗(yàn)算罕遇地震作用下的彈塑性層間位移角等指標(biāo)是否滿足規(guī)范要求，并對(duì)結(jié)構(gòu)的損傷程度進(jìn)行分析，確定結(jié)構(gòu)薄弱部位（薄弱層及薄弱構(gòu)件），根據(jù)分析結(jié)果提出抗震加強(qiáng)措施以確保結(jié)構(gòu)在各設(shè)防烈度下滿足預(yù)期的抗震性能目標(biāo)。

Abstract:Taking the Jiangxi Provincial Museum currently under construction as an example, performance-based seismic design theory and methods were combined to reasonably determine the structure′s seismic performance targets and the performance levels of the components under various seismic fortification intensities according to the importance of the building. PKPM, MIDAS and YJK software were used for elastic calculation analysis under frequent earthquakes, elastic and non-yield analysis under fortification earthquakes, and SAUSAGE software was used for elasto-plastic analysis under rare earthquakes. The elasto-plastic time-history analysis method was used to verify whether the elasto-plastic interlayer displacement angle and other indicators under rare earthquakes meet the requirements of the code, and the damage degree of the structure was analyzed to determine the weak parts of the structure (weak layers and weak components). According to the analysis results, seismic strengthening measures were proposed to ensure that the structure met the expected seismic performance targets under various seismic fortification intensities.

Keywords:out-of-code high-rise building; seismic  performance design; elastic analysis; dynamic elastoplastic analysis
