均方根位移 meaning in English

root-mean-square displacement

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
摘要根据援巴哈马体育场和援几内亚体育场主看台悬挑屋盖风洞试验数据结果，分析和探讨了采用频域分析法计算大跨度悬挑屋盖风振响应时应考虑的结构模态数和频率范围，得到强风作用下悬挑屋盖结构均方根位移与内力响应随参与计算的模态数和频率范围的变化规律，并从屋盖表面测点风压谱密度的角度解释了这种变化规律。
