Multiplicate types of structures and new technologies are applied in the project, including prestressed concrete, reinforced concrete, spatial truss, membrane and structural transfer floor etc. A finite element model of this building is built with ANSYS, and the dynamic behaviors are analyzed with the response spectrum method and time history method. Some reliable data are applied in design and construction.Keywords:complex structure; seismic response; dynamic behaviors; response spectrum method; time history method analysis廣西科學(xué)研究與技術(shù)開(kāi)發(fā)計(jì)劃項(xiàng)目(0574005)。作者簡(jiǎn)介:梁漢吉,博士研究生,高工,Email:LHJ15201@163.com。參考文獻(xiàn)[1]秦榮.計(jì)算結(jié)構(gòu)力學(xué)[M].北京:科學(xué)出版社,2001[2]謝開(kāi)仲,秦榮,彭文立,等. 北海機(jī)場(chǎng)新航站大樓網(wǎng)殼屋蓋結(jié)構(gòu)的地震反應(yīng)分析[J].廣西科學(xué),2003(4).[3]秦榮.計(jì)算結(jié)構(gòu)動(dòng)力學(xué)[M].桂林:廣西師范大學(xué)出版社,1998.[4]秦榮,謝開(kāi)仲,李秀梅,等.高層復(fù)雜結(jié)構(gòu)抗震分析[J].工程力學(xué),2004,21(增刊).
