摘要:
以随机有限元理论为基础,将框剪结构的刚度、质量、阻尼等结构参数为随机变量 .通过求解随机有限元的递推方程,得到框剪结构各层的地震动力响应均值和标准差历时曲线 .分析结构参数单独变异,以及同时变异对框剪结构地震响应的影响 .研究结果表明,对框剪结构而言,结构参数的变异对响应的均值变化影响都不大,主要是增大响应的标准差 .刚度的变异性将引起框剪结构的响应发生大幅度变异,质量的变异性影响稍小,阻尼的变异性影响不显著 .结构各参数的同时变异,对框剪结构地震响应的影响,仅比刚度单独变异的影响稍大
Abstract:
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.
