The structure system and the characteristics were pointed out and rational structural design was put forward accordingly. The results of wind tunnel test and wind vibration analysis were introduced. Using program SAP2000, the linear analysis and the section-size design were done. The stability analysis and the joint analysis were completed by program ANSYS. The main results were introduced.Keywords: large-span steel structure; structural design; wind tunnel test; stability analysis; joint analysis作者簡介:劉辰,本科,工程師,Email:liuchen@ippr.net參考文獻[1]曹登敬,郝誠新,劉楓.加蓬國家體育場看臺罩棚結(jié)構(gòu)設(shè)計[J].建筑科學,2011,27(3):87-89.[2]范峰,支旭東,錢宏亮,等.廊坊市體育場罩棚鋼結(jié)構(gòu)設(shè)計[C]//杭州:第七屆全國現(xiàn)代結(jié)構(gòu)工程學術(shù)研討會,2007.[3]沈磊,陸余年.拱桁架產(chǎn)生的水平推力下的基礎(chǔ)設(shè)計探討[J].建筑結(jié)構(gòu),2009,39(S1):800-802.[4]GB 50009—2001 建筑結(jié)構(gòu)荷載規(guī)范 [S].2006年版. 北京:中國建筑工業(yè)出版社,2006.[5]周岱,舒新玲,周笠人.大跨空間結(jié)構(gòu)風振響應(yīng)及其計算與試驗方法[J].振動與沖擊,2002,21(4):7-11.
