中文摘要 臺灣因位於西太平洋熱帶氣旋頻繁之區域,又處於環太平洋地震帶上,因此飽受颱風與地震之威脅。另一方面,隨著科技與生活日益進步,土地的開發與利用,在都市面積有限的情況下,都市中的高層建築已形成一種發展趨勢。 高層建築物除了需考量材質輕便、高強度與高容積率外,地震力與風載重的作用亦是重要的安全因素考量。本研究係使用MICRO-SAP程式中的子程式RSAP,並依據建築物耐風設計規範,以及建築物耐震設計規範及解說,並鍵入相關參數資料,建立5組範例,以靜力分析的方式,模擬在相同條件環境下,10層、15層、20層、30層樓及50層樓高度的矩形鋼結構,在地震力、風力作用下,所造成的變位影響以及建築物順風向、橫風向、扭轉向加速度及建築物角隅處之水平方向振動尖峰加速度等分析。
經由程式分析結果得知,對於鋼構建築物,受到風力及地震力作用時,會因建築物高寬比不同而有不同的影響,對於高寬比大於3之建築物,橫風向風力造成的影響可能超越順風向風力及地震力,不可忽視。

英文摘要 Taiwan is threatened by typhoons and earthquakes because of its frequent tropical cyclones in the Western Pacific and in the Pacific Rim seismic belt. On the other hand, with the increasing progress of science and technology and life, land development and utilization, in the case of limited urban area, the city's high-rise buildings have formed a development trend. High-rise buildings in addition to the need to consider the material light, high strength, and high volume rate, the seismic force and the role of wind load is also an important consideration of security factors.
In this study, we use the batch file RSAP.BAT in the MICRO-SAP program and set up five sets of examples according to the building weather resistance design specification and the seismic design of the building code in Taiwan. Under the same conditions of the environment, we analyzed the rectangular steel structures with 10, 15, 20, 30, and 50 floors under the seismic and wind forces. The calculated displacements of the building in the longitudinal, horizontal, and torsional vibration are calculated.
According to the results of the program analysis, it is known that the steel structure will have different effects on the aspect ratio of the building due to the wind force and the seismic force. For the buildings with the aspect ratio greater than 3, the vibration induced by the horizontal direction wind may go beyond those of the earthquake and wind in other directions, and it cannot be ignored.
Key words: RSAP, wind resistance design specification, high - rise building, displacement, wind force, seismic force
