  2. Based on the theory of stochastic finite element, the structural parameters of frame - shear structure including stiffness and mass and damping are simulated to be stochastic variables. by solving recurrence equation of stochastic finite element, the duration curve of mean value and standard deviation of seismic response can be obtained for every floor of frame - shear structure. an analysis is thus given to the effects of independent variation and simultaneous variation of structural parameters on the seismic dynamic response of frame - shear structure. as shown by the results, with regard to frame - shear structure, the effect of variation of strucural parameters on the change of mean value are chiefly the increase of standard deviation of response. variation of stiffness will cause the response of frame - shear structure to variate greatly ; variation of mass shows less effect ; and variation of damping shows insignificant effect. the effects of simultaneous variation of various structral parametres on seismic response are only slightly greater than the effect of stiffness variation alone

    以隨機有限元理論為基礎，將框剪結構的剛度、質量、阻尼等結構參數為隨機變量.通過求解隨機有限元的遞推方程，得到框剪結構各層的地震動力響應均值和標準差歷時曲線.分析結構參數單獨變異，以及同時變異對框剪結構地震響應的影響.研究結果表明，對框剪結構而言，結構參數的變異對響應的均值變化影響都不大，主要是增大響應的標準差.剛度的變異性將引起框剪結構的響應發生大幅度變異，質量的變異性影響稍小，阻尼的變異性影響不顯著.結構各參數的同時變異，對框剪結構地震響應的影響，僅比剛度單獨變異的影響稍大
