摘　　要：某报告厅采用钢筋混凝土框架-剪力墙结构+钢网架屋盖的结构形式。为准确对该混合结构进行分析,采用3D3S软件对上部钢网架进行计算,并导入YJK-A软件对下部钢筋混凝土结构进行设计。为保证设计的可靠性,采用MIDASGEN软件建立下部主体结构+钢网架整体模型进行补充分析,对下部结构和网架的各项指标分别进行对比。结果表明整体模型与独立模型计算结果接近,支座刚度推导及简化方法合理,设计结果可靠。The structural system of a lecture hall is RC frame-shear wall structure with steel space grid roof.In or⁃der to analyze the mixed structure accurately,3D3S software is used to calculate the space grid,and YJK-A software is used to design the main RC structure.To ensure the reliability of design,MIDAS GEN software is used to estab⁃lish an overall model for supplementary analysis.Various indicators of the main RC structure and space grid are com⁃pared.The results indicate that the results of the overall model are close to those of the independent model,the deri⁃vation and simplification method of the support stiffness is reasonable.
