［摘要］采用MIDAS/Gen軟件分別建立了黃驊市天健湖文體公園體育中心體育館主體混凝土框架單體模型和結(jié)構(gòu)總裝整體模型，對比分析了結(jié)構(gòu)在單體模型和整體模型下，主體混凝土框架的力學(xué)性能差異。結(jié)果表明：在靜力荷載作用下，采用單體模型計算主體混凝土框架與采用整體模型計算結(jié)果有一定差異，框架柱軸力計算結(jié)果偏于安全，彎矩結(jié)果存在較大差異，環(huán)梁軸力吻合較好。在地震作用下，采用兩種模型計算的結(jié)構(gòu)側(cè)向變形及基底反力差異較小，單體模型計算結(jié)果偏安全。在不同地震烈度下，單體模型與整體模型表現(xiàn)出較大差異，建議補充整體模型校核，以確?？拐鹪O(shè)計安全。［關(guān)鍵詞］黃驊市天健湖文體公園; 體育中心體育館; 網(wǎng)殼; 總裝分析; 單體模型中圖分類號：TU393.3 文獻標識碼：A 文章編號：1002-848X(2015)16-0026-04

Abstract: 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.Keywords: Tianjian Lake Cultural Park of Huanghua City; gymnasium of sports centre; latticed shell; whole structure analysis; partial model
