【摘要】 开合屋盖结构由于具备适应各种天气状况的性能,在大型多用途体育场馆中得到了广泛应用。由于其结构形式的特殊性,在不同的使用状态下有不同的动力性能。本文以浙江省黄龙体育中心网球馆开合结构为分析对象,通过计算活动屋盖分别在开启和闭合锁定状态下结构的动力特性,以及结构在水平、竖向地震作用下的地震响应,探讨了该结构的抗震性能。在分析研究的基础上,参考以往的设计经验,讨论该类结构抗震设计的一般原则,提出了开合结构的抗震构造措施。更多还原

【Abstract】 Retractable roof structures have become common recently,especially in the field of large sized multipurpose sport centers.Because of the special structure style,the structures with retractable roofs are different from the conventional structures.There are different dynamic characteristics in different working conditions.This paper uses a retractable roof structure in Zhejiang Province as an example.Through calculating the dynamic characteristic at both open and close locking states and analyzing the response of structure subjected to horizontal and vertical earthquake force,the earthquake-resistance of the structure is analyzed.Based on the research,the authors make a suggestion on the earthquake-resistant measures of the structure.更多还原
