  • 台灣地區頻受颱風的肆虐,每當颱風過境之時不乏出現建築物相關帷幕牆破壞案例。本研究採用東京工藝大學風洞實驗之風壓系數歷時資料,以高層建築物帷幕牆之固定系統的鋼制螺栓為例,主要探討颱風對高層建築物所造成平均疲勞破壞指數的模擬。藉(Kumar,1997)所提電腦模擬法產生特性相似的資料取代原始資料,藉縮尺轉換得實場資料並換算得應力資料,以雨流法建立應力與週期的關係及材料的載重壽命曲線,Palmgren-Miner計算法求得在破壞線性累積假設下的實際解。第二種是用風洞實驗數據之特性參數以及材料的載重壽命曲線,藉縮尺轉換得實場資料並換算得應力資料,由Rayleigh估計法求得隨機過程呈高斯窄頻假設下的公式解,運用頻寬修正項與非高斯修正項得適用廣泛的公式解。


    Taiwan Region frequency of the raging typhoon, whenever the transit of typhoon appears quite relevant building curtain wall damage case. The study process with Tokyo University wind tunnel wind pressure factor experiments lasted for information to high buildings curtain wall of the fixed system of steel and bolt, main explore typhoon for high-rise buildings fatigue failure caused by average index simulations. With (kumar,1997) of computer simulation method produces characteristics similar information replaces the original information to enable the zoom scale conversion of real-farm data and converting it to rain stress data flow established stress and cycle and the relationship between material life of load curve, palmgren-miner calculation seek to undermine linear cumulative assumptions about the actual. The second is the wind tunnel test data and material parameters of the characteristics of the load life curve with zoom feet conversion of real-farm data conversion to stress and information provided by the estimated rayleigh Law process is a random Gaussian narrowband assumes that the formula that use bandwidth correction in conjunction with the non-Gaussian correction is applied to a wide range of formulas.
