【摘要】 结合工程实例,采用3D3S软件和SAP2000软件分别从结构模态、地震作用和力学性能三个方面对整体建模与上部屋盖单独建模的工作性能进行了对比分析,得出单独采用上部结构建模分析偏于不安全,建议在条件允许的情况下进行整体分析设计。更多还原

【Abstract】 Combining with the engineering example,the paper adopts the 3D3S and SAP2000 software to undertake the comparison and analysis of the overall modeling and upper roof separate modeling from the structural mode,the seismic effect and the dynamic performance,concludes the upper structure model analysis is a little unsafe,so the overall modeling design should be undertaken in permitted condition.更多还原
