pressure-induced spectrum
解釋
壓力感生光譜-
Mean shape factor and rms shape factor distributed on the roof of the structure with b exposure are measured. based on using of a multi - point high - speed pressure scanning system on rigid model, wind - induced dynamic responses are discussed by the method of power spectrum analysis
分析了在b類地貌類型下風荷載的分佈特性，並根據剛性模型同步測壓技術以及屋蓋結構風致響應的譜分析方法，分析討論了結構動態響應，並討論了結構前幾階模態對系統響應貢獻。 -
The mode number and the frequencies range, which were considered during calculating the wind - induced responses of large cantilevered roof by using the method of frequency domain, were analysed and discussed, according to the results of wind tunnel tests of bahamas and guinea stadium grandstand cantilevered roofs, and the rules that rms displacement and rms internal force responses under strong wind force changing with participant modes number and frequencies range were obtained, and which could be explained from the point of wind pressure power spectrum densities of the measured points on surface of the roof
摘要根據援巴哈馬體育場和援幾內亞體育場主看臺懸挑屋蓋風洞試驗數據結果，分析和探討了採用頻域分析法計算大跨度懸挑屋蓋風振響應時應考慮的結構模態數和頻率范圍，得到強風作用下懸挑屋蓋結構均方根位移與內力響應隨參與計算的模態數和頻率范圍的變化規律，並從屋蓋表面測點風壓譜密度的角度解釋了這種變化規律。
