【摘要】 斗屏是一种柔性悬挂于体育馆屋盖中央的大型显示设备,自北京奥运会以来,在我国体育馆中的应用逐渐增多。国内外常见的体育馆斗屏重量从几吨到数十吨不等,其重量和悬挂方式对屋盖结构的力学性能产生了显著影响,受到了广泛关注。为了揭示斗屏对大跨屋盖结构自振特性、地震响应以及抗连续倒塌性能的影响规律,加强地震作用、断索影响等情况下屋盖和斗屏的安全性,国内外学者从网壳结构、网架结构、索穹顶结构和弦支穹顶结构等常见体育馆屋盖结构入手,对悬吊斗屏大跨屋盖结构抗震性能及抗连续倒塌性能进行了深入研究。总结了国内外研究中提出的降低斗屏不利影响的相关措施,为悬吊斗屏的大跨屋盖结构设计提供了参考。更多还原

【Abstract】 The center-hung scoreboard is a large, flexible display device suspended at the center of sports arena roofs.Since the Beijing Olympics, its application in Chinese sports venues has grown significantly. The weight of center-hung scoreboards in both domestic and international arenas varies from several tons to tens of tons, with their weight and suspension methods significantly impacting the structural mechanics of roofs, thus attracting widespread attention. To examine the effects of center-hung scoreboards on the natural vibration characteristics, seismic response, and progressive collapse resistance of large-span roof structures, and to enhance the safety of both roofs and scoreboards under seismic events and cable failure scenarios, scholars worldwide have conducted extensive research on the seismic performance and collapse resistance of large-span roof structures with center-hung scoreboards. This research has primarily focused on common sports hall roof types, including lattice shell structures, grid structures, cable dome structures, and suspen-dome structures. This paper summarizes the seismic mitigation measures proposed in studies worldwide to reduce the adverse effects of center-hung scoreboards, providing valuable reference points for the design of large-span roof structures with suspended scoreboards.更多还原
