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作者简介：刘正才，博士，教授，Email：Liuzhengcai1@163.com。参考文献［1］傅学怡. 实用高层建筑结构设计［M］. 北京：中国建筑工业出版社，2010.［2］朱炳寅.建筑抗震设计规范应用与分析 GB 50011—2010［M］. 北京：中国建筑工业出版社，2011.［3］朱炳寅. 高层建筑混凝土结构技术规程应用与分析 JGJ 3—2010 ［M］. 北京：中国建筑工业出版社，2013.［4］GB 50011—2010 建筑抗震设计规范［S］.北京：中国建筑工业出版社，2010.［5］GB 50010—2010 混凝土结构设计规范［S］.北京：中国建筑工业出版社，2011.
