摘　　要：采用MIDAS/Gen软件分别建立了黄骅市天健湖文体公园体育中心体育馆主体混凝土框架单体模型和结构总装整体模型,对比分析了结构在单体模型和整体模型下,主体混凝土框架的力学性能差异。结果表明:在静力荷载作用下,采用单体模型计算主体混凝土框架与采用整体模型计算结果有一定差异,框架柱轴力计算结果偏于安全,弯矩结果存在较大差异,环梁轴力吻合较好。在地震作用下,采用两种模型计算的结构侧向变形及基底反力差异较小,单体模型计算结果偏安全。在不同地震烈度下,单体模型与整体模型表现出较大差异,建议补充整体模型校核,以确保抗震设计安全。Two models of gymnasium of sports centre in Tianjian Lake Cultural Park of Huanghua City,which included partial model of the main concrete frame structure and the whole structure,were built respectively by MIDAS / Gen software.The differences of mechanical performances of the main concrete frame of partial model and whole model were also compared. The results show that differences in calculation results of the main concrete frame are found between partial model and whole model under static loads. The axial force results of frame columns are rather safe and those of ring beam in different models agree well. But the bending moment results of frame columns show great difference. And the lateral displacement and base reaction obtained by two models have little difference. Calculation results of partial model are more safe. Large differences are found between partial model and whole model in different seismic precautionary intensities. In order to ensure the safety of earthquake design,whole model check is suggested to be a supplement.
