[摘要] 我國(guó)抗震設(shè)防地區(qū)超高層建筑的實(shí)際抗震性能日益引起學(xué)術(shù)界與工程界的關(guān)注。盡管我國(guó)2010年版《高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程》已經(jīng)正式納入了抗震性能設(shè)計(jì)方法，但在實(shí)際超高層建筑的分析與設(shè)計(jì)中如何具體合理應(yīng)用這一方法，還處于探索階段。本文基于《高規(guī)》建議的性能化分析方法，采用非線性分析軟件Perform-3D，對(duì)重慶市某250m高超高層框架一核心筒建筑進(jìn)行了性能評(píng)估，并結(jié)合概念設(shè)計(jì)，綜合評(píng)價(jià)了該建筑的抗震性能。

Abstract: The seismic performance of super high rise buildings located in seismic regions in China has attracted the attention of engineers and researchers in recent years. Although the "Technical specification for concrete structures of tall building (2010 Edition)” has adopted the performance based seismic design method, the application of this method in the design and evaluation of super high rise buildings is still under investigation. Based on the code specified seismic performance based design procedure, a 250 meters tall building in Chongqing was analyzed using the nonlinear analysis program Perform-3D to examine it seismic performance. The analysis results are used to comprehensively evaluate the seismic performance of the structure.

Keywords: super high rise structure; seismic design; performance based design; Perform-3D
