摘　　要：为研究经济性最优的楼盖体系,利用有限元分析与设计软件SATWE软件,对某工程实例进行设计分析。通过研究柱网6 m×9 m,建筑层高3.9 m,350 mm厚板的地下车库设计分析,对梁高及跨度也做了理想化处理,在满足建筑净空要求和结构安全的前提下,模拟了3种次梁布置方案结果并进行对比,讨论地下结构顶板楼盖的次梁布置方式对结构经济性的影响。In order to study the most economical floor system,the finite element analysis and design software SATWE is used to design and analyze an engineering example.By studying the design and analysis of the underground garage with 6m×9m column net,3.9m building height and 350mm thick plate,the beam height and span are also idealized.Under the premise of meeting the building headroom requirements and structural safety,the results of three sub-beam layout schemes are simulated and compared,and the influence of sub-beam layout on the structural economy of the underground structure roof floor is discussed.

关 键 词：地下结构 梁板楼盖 次梁布置方式 单向板 双向板 经济性指标
