According to function of building,two kinds of structure column nets are selected,the amount of concrete and steel bar is computed with different floors structures and base forms. Combined with the corresponding statistical analysis of the comprehensive cost,the advantages and disadvantages of various structure forms are stated. The statistical results could be a basis of the preliminary design,also could provide a reference for the design of similar engineering structure.%为满足地下汽车库停车要求,建筑专业通常采用两种柱网,一般为8.1 m×8.1 m或5.8 m/5.2 m×8.1 m,根据以上两种柱网,选择不同顶板楼盖方案进行了结构设计比较,且计算了相应钢筋与混凝土用量的经济性指标,同时阐述了各种顶板楼盖布置形式的优点与不足,并提出了控制地下汽车库经济性的结构方案选型建议,统计结果可作为前期同甲方交流及初步设计的参考,也可为类似工程结构设计提供借鉴.
