开合屋盖结构的发展及开合机理研究

开合屋盖的开合方式的选择是这类建筑设计的难点之一。回顾开合结构的发展过程 ,对现有诸如美国匹斯堡市民体育场、加拿大蒙特利尔奥运会体育馆、加拿大天空穹顶、日本福冈棒球馆、日本海洋穹顶、日本富山球穹顶、荷兰阿姆斯特丹体育场、日本小松穹顶、美国威斯康星洲米勒棒球场、2 0 0 2年世界杯足球赛的日本大分县体育公园体育场等开合屋盖建筑的开合方式进行了研究和总结 ,指出了开合屋盖结构的发展趋势 ,提出了根据建筑平面投影和立面形状划分开合方式的原则和方法 ,给出了开闭式屋盖的评价标准

RESEARCH ON DEVELOPMENT OF RETRACTABLE STRUCTURES AND RETRACTABLE MECHANISM

Retractable method is one of the most difficult points when a stadium with retractable roofs is to be designed. In this paper, development of retractable structures is reviewed. Then, aiming at the recently constructed typical retractable buildings, such as Pittsburgh Civil Arena, Montreal Olympic Stadium, Tornoto Sky Dome, Fukuoka Dome, Ocean Dome, Ball Dome, Amsterdam Arena, Komatsu Dome, Miller Park, Ohita Dome, etc, all possible retractable methods are summarized. Thereafter, the developing trend of retractable buildings is studied. Furthermore, the new partition principles and methods of retractable roofs are put forward according to both projection of roof on horizontal plan and vertical figure of buildings. Finally, the criterion of evaluating retractable buildings is given.
