A new type structure design software, YJK software, was used for structural design of a high-rise building made of three shear wall structure residential towers and a two-layer commercial podium. The calculation model selection way and calculation parameter setting method were elaborated combined with the code requirements. And comparative study was made in aspects from the seismic grade setting of the basement, basement outer wall calculation and checking calculation model, the reinforcement model of rectangular section beam, selection of the reinforcement model of column-wall composite section, slab analysis method and the beamslab coordination model. The results show that the rational calculation model and parameters setting based on the code specification can effectively avoid the waste of material and lead a reasonable reinforcement of the structure.Keywords: structure design; basement outer wall; side frame column; finite element analysis; YJK software作者簡介：劉正才，博士，教授，Email：Liuzhengcai1@163.com。參考文獻［1］傅學怡. 實用高層建筑結構設計［M］. 北京：中國建筑工業(yè)出版社，2010.［2］朱炳寅.建筑抗震設計規(guī)范應用與分析 GB 50011—2010［M］. 北京：中國建筑工業(yè)出版社，2011.［3］朱炳寅. 高層建筑混凝土結構技術規(guī)程應用與分析 JGJ 3—2010 ［M］. 北京：中國建筑工業(yè)出版社，2013.［4］GB 50011—2010 建筑抗震設計規(guī)范［S］.北京：中國建筑工業(yè)出版社，2010.［5］GB 50010—2010 混凝土結構設計規(guī)范［S］.北京：中國建筑工業(yè)出版社，2011.
