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MIDAS GEN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.
Abstract
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.
