【摘要】：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。
[Abstract]:This paper puts forward the method of combining field vibration measurement with questionnaire to solve the problem of researchers' comfort, taking the large span floor sports ground of the National Fitness activity Center of Ikinhoro Banner as the engineering background. The vibration of the floor is measured in detail before and after decoration, and its dynamic characteristic parameters are determined. In the operation phase after the building decoration, carry on the normal use state (basketball training) under the spot vibration test, at the same time, the athletes, coaches. Audience sent questionnaires to record their comfort. Take Beijing Jiaotong University Gymnasium Basketball match as a similar case. Field vibration test and questionnaire survey. The results show that: the wood floor decoration layer has a great impact on the vibration value, but will not have a greater impact on the comfort of the personnel; Although the excellent frequency of large-span floor is 2 ~ 3 Hz, the reasonable design can also meet the control requirements of personnel comfort. The measured data provide a reference for the evaluation of the comfort degree of athletes and spectators in the gymnasium.

【正文快照】： 近年来,多层大跨(悬挑)空间结构越来越多被城市所应用,如CCTV新塔楼、深圳证交所塔楼等以办公为主的高层异形建筑和不胜枚举的会展类建筑,跨度(悬挑)动辄超30 m;更有甚者,如伊金霍洛旗全民健身中心、北京大学附属小学等多层体育建筑,出现了在40 m跨度楼层上设置运动场的情况[1
