The layout increased effective floor area of each story by nearly 10% due to the elimination of the areas of the aisles around core wall, which created good transparent environment from north to south and eliminated dark rooms in the middle. In sum, it improved the architectural functions a lot. Transfer structures of steel reinforced concrete V-shaped braces were used to replace removed inner columns to fulfill the large space demand of the lobby at first floor. The out-of-code items, seismic fortification goal and structural system selection and features were introduced. Dynamic elastic-plastic time-history analysis was conducted on the structure by software ABAQUS. The potential weak parts expected to crack under the rare earthquake were found out and strengthened. It is proved that all the performance indexes meet the requirements of the seismic fortification goal.Keywords:seismic design; high-rise building; structural layout; frame-shear wall structure作者簡介：高建民，學(xué)士，教授級高級工程師，一級注冊結(jié)構(gòu)工程師，Email:gaojianmin3132@163.com。參考文獻(xiàn)［1］JGJ 3—2002 高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程［S］.北京：中國建筑工業(yè)出版社，2002.［2］GB 50011—2001 建筑抗震設(shè)計規(guī)范［S］.北京：中國建筑工業(yè)出版社，2001.
