【摘要】 体育场馆多数需要大跨度空间,如何通过空间结构选型实现其安全、经济、适用和美观的综合指标是一个重要的问题。对国内体育场馆的大跨度空间结构选型进行调研。对调研情况进行分析可知,国内最常用的结构类型主要有网架结构、桁架结构和网壳结构3种,而国外的体育场馆建设在结构选型时更为丰富,此外,由于资金和技术方面的原因,国内体育场馆跨度普遍偏小。此外,在我国的各类大跨度体育场馆建设中,网架结构最早得到发展,桁架结构和网壳结构次之,膜结构发展得最晚。因此,我国的大跨度体育场馆建设应加强对新材料和新结构类型的研究,综合考虑各方面的因素选择最合理的结构类型,在赋予大跨度屋盖一些新的功能,在获得更佳的使用体验的同时,也延长其服役年限。更多还原

【Abstract】 Most of the stadiums need large span spaces.It is important to obtain a good composite index of safety,economy,applicability and beauty through the structural form selection.In this paper,the structural form selection of lots of large span stadiums in China is discussed by statistics and analysis.The most commonly used structure types in China are mainly grid structures,truss structures,and llattice shell structures.The structural forms of foreign gymnasiums are more diverse.In addition,due to the financial and technical reasons,the spans of domestic gymnasiums are usually small.In addition,in China,the grid structure is developed at the earliest,after which the truss structure and the shell structure are then developed.The membrane structure only appears recently.Therefore,to promote the development of long-span gymnasiums in China,researches of new materials and new structure types should be conducted;different factors to select the most reasonable structure type should be considered,and new functions of long-span structures should be exploited,so as to give better user experience and to extend their service life.更多还原
