The perimeter columns are curved from bottom to top and inclined inwards. The arc steel sail with height of 37m is settled on the roof. According to the characteristics of the project, main structure system, the design of the inclined columns, details of typical joints, the research on the wind tunnel experiment of special shape building, and the design of the arc steel sail on the roof were introduced. Static analysis of the whole structure under frequent earthquakes and nonlinear static analysis under rare earthquakes were carried out. The connection of steel members and concrete structure were reinforced.Keywords: harbor museum; spiral curved surface; arc steel sail; inclined column; the wind tunnel experiment of special shape building; nonlinear static analysis作者簡介:黃建林,學士,工程師,Email:jianlin_huang@acctn.com。參考文獻[1]徐培福,傅學怡,王翠坤,等. 復雜高層建筑結(jié)構(gòu)設計[M].北京:中國建筑工業(yè)出版社,2005.[2]GB 50009—2012建筑結(jié)構(gòu)荷載規(guī)范[S].北京:中國建筑工業(yè)出版社,2012.[3]盧占斌,魏慶鼎,王安武.龍脊風帆模型氣動特性風洞實驗[J].流體力學實驗與測量,2001,15(4):46-52.[4]北京邁達斯技術有限公司.MIDAS/Gen 用戶技術手冊(中文)[M].[5]GB 50011—2010建筑抗震設計規(guī)范[S].北京:中國建筑工業(yè)出版社,2010.[6]沈國輝,樓文娟,錢濤,等. 寧波·中國港口博物館風振計算報告[R].杭州:浙江大學建筑工程學院,2012.
