而於文中分析的方式，為計算不同模型的風壓實驗數據的基底風力及其風力係數，再以實場十分鐘為段取各方向風力之極值與發生極值下對應的其他方向之值，接著透過統計特性與各方向風力與及值間的比值之關係的機率分佈，提出建議的風力組合係數，期望未來能運用於載重組合係數之推估及相關研究。 Wind loads acting on high-rise buildings can be categorized as alongwind, acrosswind and torsional wind loads. The current Taiwan building wind code stipulates to use the largest alongwind, acrosswind and torsional wind loads together as the building design wind loads. However, the largest value of these three wind loads may not occur simultaneously. In this thesis, wind loads of rectangular shaped building models of various side ratio and aspect ratio, obtained from pressure measurements were used to investigate the correlations among three wind loads. Each set of wind loads were divided into 36-40 10-minutes length records. For each 10-minute record, the largest value of alongwind/ acrosswind/ torsional wind load together with the other two wind loads occurred at the same time were established. The mean values, standard deviations and conditional probability mass functions for the other two wind loads under the condition of one certain extreme wind load were calculated for all cases. The correlations of wind loads under the condition of certain extreme wind load were studied. Based on these conditioned statistical characteristics of winds loads, a simplified combination for design wind loads was proposed.
