  • 由於風效應對於高層建築物的影響特別顯著,而在擁擠的都會區高層建築物逐漸的普遍,因此鄰棟間之相互影響變得相當重要,因此,本研究透過風洞試驗來瞭解風對於高層建築物之效應。
    首先,本文進行鄰棟高層建築物影響風力負載型態之風洞實驗,主要在探討周遭地況環境對於目標建物受風作用下之基底剪力及彎矩之影響,本實驗所分析之目標建物總高度為25層樓,高為92.5公尺,利用縮尺模型量測當目標建物在不同之地況環境,受其他高樓遮蔽時之基底剪力及彎矩,風攻角每10度量測一次,吹拂36個風攻角,計算風力係數及其載重組合後還原至真實目標建物之受力。
    研究結果發現,在四種地況中,載重組合在地況C(實際遮蔽情形)時出現最大值;關於鄰棟建築物對於立面附屬構造之受風影響,本文針對台灣之長年風向做一探討比較;結果發現,在不同地況下(鄰棟高層建築物之排列不同),目標建物之受力行為即有所不同,因此,在進行高層建築物之設計時應進行風洞試驗量測風壓及風力實驗以了解細部流場行為。

    Due to the wind effect which works particularly within high-rise buildings, and tall buildings in crowded metropolitan areas which are built generally, it is very important to make tall buildings space closely on wind-induced loading. We can learn through the wind tunnel study to understand the effect of the wind for the tall buildings.

    First, in this thesis, I am going to talk about the Wind Tunnel study of interference effects to closely-spaced tall buildings on wind-induced loading. Second, I explore the main structure of the base shear force and base moment force in different environments. The main structure is 25 floors and height of 92.5 meters in this lab. I use the measurement scale model when the main structure in different environmental conditions is sheltered by the base shear and moment force from other tall building. If Wind Direction is measured once every 10°, that could be calculated out the wind factor and restore the load combinations. In these experiment results, the maximum of load combinations is fitted in the environment C. I offer the reference to compare the façade-attached accessories effected by conventional wind. Finally, the wind-induced loading occurs differently in different environments. In addition, it should be carried out Wind Tunnel Study in order to understand the behavior of tall buildings flow field details.
