The cost control method of structural design of the basement was put forward. The results show that the adoption of HRB500 is preferred to HRB400 when the reinforcement of design is controlled by calculation. The cost per unit area of the basement with small column grid is economy. The flat slab is the most economic when the small column grid is adopted. For large column grid, ribbed floor with one secondary beam in long side direction is the most economic. Other reasonable structural optimization design methods were also presented to reduce the cost.Keywords: column grid; floor system; exterior wall; constructional detail作者簡介：汪梅，碩士，工程師，Email：wangmei930@qq.com。參考文獻(xiàn)［1］GB 50011—2010 建筑抗震設(shè)計規(guī)范［S］. 北京：中國建筑工業(yè)出版社，2010.［2］GB 50010—2010 混凝土結(jié)構(gòu)設(shè)計規(guī)范［S］. 北京：中國建筑工業(yè)出版社，2011.［3］徐傳亮,光軍.建筑結(jié)構(gòu)設(shè)計優(yōu)化及實(shí)例［M］.北京：中國建筑工業(yè)出版社，2012.［4］JGJ 3—2010 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，2011.［5］11G 101-1 混凝土結(jié)構(gòu)施工圖平面整體表示方法制圖規(guī)則和構(gòu)造詳圖［S］. 北京：中國計劃出版社，2011.［6］GB 50007—2011 建筑地基基礎(chǔ)設(shè)計規(guī)范［S］. 北京：中國建筑工業(yè)出版社，2012.［7］GB 50009—2012 建筑結(jié)構(gòu)荷載規(guī)范［S］. 北京：中國建筑工業(yè)出版社，2012.
