| Summary: | 碩士 === 國立臺灣科技大學 === 營建工程技術學系 === 83 === Strong wind in Taiwan is mainly caused by typhoons. One
objective of this study is to obtain n-year(n=100,50,
25,10,0.5) return period wind speed and the probability
distributions of n-year maximum wind speed. The design wind
speeds of 24 stations are derived based on typhoon wind speed
data between 1947 and 1991. The directional effect of wind
speed is also studed. Since comfortability conside- ration
plays an important role in tall building design, the second
objective of this thesis is to study the reliabi- lity of
relevant code provisions. A new provision with uniform bound
for the fundamental period assures consistent comfortability
criterion among different tall buildings. The top floor
acceleration , upon which comfortability criterion is based, is
composed of contribution from the along-wind, across-wind and
rotational directions. The proposed analytic reliability method
allows extensive parameter study.
