［摘要］黃驊市天健湖文體公園體育中心屋蓋鋼結(jié)構(gòu)由游泳館屋蓋鋼結(jié)構(gòu)、體育館屋蓋鋼結(jié)構(gòu)和連接走廊屋蓋鋼結(jié)構(gòu)3部分構(gòu)成，結(jié)構(gòu)形式為弦支網(wǎng)架。介紹了屋蓋鋼結(jié)構(gòu)的分縫及結(jié)構(gòu)體系的選定過程，詳細闡述了恒荷載、活荷載、風(fēng)荷載等主要荷載作用的取值，并對屋蓋鋼結(jié)構(gòu)靜力、動力反應(yīng)進行了分析。結(jié)果表明，在各種設(shè)計荷載作用下屋蓋鋼結(jié)構(gòu)設(shè)計能夠滿足相關(guān)規(guī)范的要求。［關(guān)鍵詞］天健湖文體公園; 空間鋼結(jié)構(gòu); 弦支網(wǎng)架; 動力反應(yīng)中圖分類號：TU393.3 文獻標識碼：A 文章編號：1002-848X(2015)16-0022-04
Structural design on the space grid with suspend string of the roof of sports center in Tianjian Lake Cultural Park of Huanghua CityWang Danni1, Yu Jinghai1,2, Yan Xiangyu1,2, Han Juan1, Guo Hongyun1,3, Dou Yubin1(1 Architectural Design and Research Institute of Tianjin University, Tianjin 300073, China; 2 Tianjin Steel Building Structure Engineering Center, Tianjin 300072, China; 3 School of Civil Engineering, Tianjin University, Tianjin 300072, China)Abstract: The steel structure of the roof of sports center in Tianjian Lake Cultural Park of Huanghua City consists of three parts, including the steel roof natatorium, the steel roof gymnasium and the steel roof of connecting corridor. The structural style is space grid with suspend string. The process of the structural system and setting principle of the gaps of the steel roof were introduced. The values of dead load, live load and wind load were elaborated. The static and dynamic structural responses were also analyzed. Results show that the design of the steel roof can satisfy the criterion demands under all design loads.Keywords: Tianjian Lake Cultural Park of Huanghua City; spatial steel structure; space grid with suspend string; dynamic response
