大跨度楼盖运动场内人员舒适度实测分析研究

摘要

A method combining field vibration tests and questionnaires to analyze human comfort was proposed. Taking the gymnasium of National Fitness Center in Ejinhoro Banner with long-span floor as an engineering background, detailed vibration tests on the long-span floor were carried out before and after the decoration,and the dynamic parameters of the long-span floor were obtained through these tests.The field vibration tests under a normal working condition (basketball training)was conducted after the decoration,and questionnaires were issued to athletes,coaches and spectators to record their feelings.Taking a basketball game in Beijing Jiaotong University Gymnasium as a similar case, the field vibration tests and questionnaires were also conducted.The results show that,the wood floor decoration layer has a great influence on the vibration magnitude,but has no greater impact on the human comfort.The long-span floor's predominant frequency is about 2-3 Hz,but it can still meet the control requirements of human comfort by suitable designing.The field test data provide a reference to the comfort evaluation for athletes and spectators in stadium.%提出采用现场振动实测与调查问卷相结合的方法研究人员舒适度问题。以伊金霍洛旗全民健身活动中心大跨度楼盖运动场为工程背景，在建筑装修前和装修后对该楼盖进行详细的现场振动实测，明确其动力特性参数；在建筑装修后的运营阶段，进行正常使用状态（篮球训练）下的现场振动测试，同时对运动员、教练员、观众发放调查问卷记录其舒适度。以北京交通大学体育馆篮球比赛作为相似案例，进行现场振动测试和调查问卷。研究得出：木地板装修层对振动量值有很大影响，但不会对人员舒适度有较大影响；大跨度楼盖虽然卓越频率在2～3 Hz，但是经合理设计也能满足人员舒适度控制要求。以实测数据为体育馆内运动员及观众舒适度评价提供了参考。
