    Abstract: 建築物在受風擾動下,除了安全性上受關注,其使用人員的舒適度在結構設計裡亦是一個重要的議題。對於建築物受風影響造成的振動,其舒適度規範的制定長久以來一直備受爭議,除了身體因素之外,還包括心理因素等眾多因素影響。最近台灣風力規範訂定之舒適度標準為5 mm/sec²加速度,其對應之回歸週期為半年。


    Under wind disturbance, the comfort of occupants in buildings is an important issue in the structural design aside from safety consideration. The human comfort criterion for wind-induced motion has been a long-time controversial issue because many factors, either physiological or psychological, can considerably differentiate the outcome. Recently, a constant criterion of 5 cm/sec2 for a half-year return period was regulated in Taiwan building wind code.
    In an attempt to build up the local data base in preparation for improving the building wind code in the future, this research aims to conduct surveys to investigate the comfort criteria by using a motion simulator newly constructed at the wind engineering research center, Tamkang University. A methodology and feasible procedure to determine the comfort threshold and the return period were proposed in this study. Two surveys (one tentative and one formal) using harmonic motion have been performed to obtain the comfort thresholds for 2%, 10% and 50% of people objecting and their corresponding return periods.
    The results show that (1) comfort thresholds are frequency-dependent within 0~1 Hz; (2) people with body orientation in fore-aft direction are more senitive to vibration than in side-to-side direction. However, it is found that, following the methodology proposed, the return period obtained does not reasonably increase with percentage of people objecting. It is due to the assumption of the same Poisson distribution for each vibration case in the methodology, which is to be improved in the future consecutive studies.
