［摘要］停建多年的工程項(xiàng)目重新續(xù)建時(shí)，由于適用設(shè)計(jì)規(guī)范的更新，新建與已建結(jié)構(gòu)的連接等均需要妥善處理。對(duì)處于高烈度區(qū)的某超高層建筑續(xù)建工程，采取抗震性能設(shè)計(jì)方法對(duì)其已建成部分結(jié)構(gòu)和續(xù)建結(jié)構(gòu)方案進(jìn)行整體分析和可行性論證。結(jié)果表明，擬采用的“鋼管混凝土框架柱+鋼框架梁+鋼筋混凝土核心筒+角部支撐”的組合結(jié)構(gòu)體系可行，在小震作用下既有結(jié)構(gòu)構(gòu)件能夠達(dá)到抗震設(shè)防性能目標(biāo)要求，在中大震作用下既有結(jié)構(gòu)部分墻柱加固處理后可以達(dá)到抗震設(shè)防性能目標(biāo)要求。

Abstract:When the project that has been suspended for many years is reconstructed, due to the update of the applicable design specifications, the connection between the new and existing structures needs to be properly handled. For the reconstruction project of a high-rise building in high earthquake intensity area, the  performance\|based seismic design method was adopted to carry out the overall analysis and feasibility demonstration of the completed partial structure and the reconstruction structure plan. The results show that the proposed structural system of "concrete filled steel tubular frame column + steel frame beam + reinforced concrete core tube + corner brace" is feasibility, the existing structural members can meet the requirements of seismic fortification performance under the action of frequently earthquake, and some shear walls and columns of existing structures can meet the requirements of seismic fortification performance after strengthening under the action of local fortification earthquake or rarely earthquake.

Keywords:super high-rise building; reconstruction; performance-based seismic design
