摘要
基于体育场馆趋于大空间、大跨度、多功能、更舒适的发展趋势,文章结合结构振动的原理,分析体育场馆在各种运动状态下产生振动的原因,得到常见运动方式对体育馆的荷载激励;为了减小结构在各种运动荷载下的振动响应,给出减小体育场馆结构振动的设计建议;根据虚功原理分析在运动人群有节奏运动下楼板的最大加速度,提出控制运动人群有节奏运动以及采取增大结构自振频率、适当控制群体运动方式、设置调谐质量阻尼器(tuned mass damper,TMD)的减振控制措施。该文的研究为大型体育场馆的减振设计提供了一定的参考。
Based on the developing trend of large space,large span,multi-function and comfortability for stadiums,this paper analyzes the reason of vibration for stadiums according to the structural mechanics.Dynamic excitation of various human-induced activities is proposed.In order to decrease the structural vibration response of stadiums under various exercise load,some design suggestions are put forward to reduce the vibration.Meanwhile,the maximum acceleration of floor under rhythmic exercise of sports crowds is analyzed based on the principle of virtual work,and the corresponding suggestions on reducing the acceleration are proposed.Furthermore,a series of vibration reduction methods are introduced,including increasing the natural frequency,controlling the exercise mode of group activities and adding tuned mass damper(TMD).The research results can provide a reference for the vibration reduction design of large stadiums.
