The goal of this paper is to develop the long period attenuation relationships for horizontal acceleration response spectrum of rock site in china 本文建立了我國水平向基巖長周期加速度反應(yīng)譜衰減關(guān)系。
3 . for three kinds of different soil layer construction , the characters of the platform values and the characteristic periods of ground surface acceleration response spectra were studied 3系統(tǒng)地研究了軟夾層在底部、中部和頂部的三種土層結(jié)構(gòu)的反應(yīng)譜平臺值和特征周期的主要特征。
This paper describes the vibration equation of this structure , and derives the horizontal vibration displacement and acceleration response spectrum and the mean square response on the base of the complex modal analytical theory 建立該結(jié)構(gòu)體系在脈動風(fēng)作用下的振動方程,基于隨機振動的復(fù)模態(tài)理論,推導(dǎo)位移和加速度響應(yīng)譜及均方響應(yīng)的表達(dá)式。
Then the transform method and the digital broad - band data from china is applied to obtain the wide period attenuation relationships for horizontal acceleration response spectra of eastern china and western china in rock sites ( c , = 5 % ) 最后用常規(guī)的轉(zhuǎn)換方法,并加入我國158條水平向?qū)掝l帶數(shù)字記錄,建立了中國東部和西部地區(qū)的水平向基巖寬周期( t = 0 . 04 - 20s , = 5 )加速度反應(yīng)譜衰減關(guān)系。
