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

本文採用了更接近實際的力學模型，主結構採用彎曲剛度，子結構採用剪切剛度，利用隨機振動復模態理論，推導了巨型框架減振結構的動力響應表達式，並以日本東京市政一號樓為基本模型，討論了巨型框架減振結構兩種結構形式（座承式和懸掛式）的主要參數（剛度和阻尼）對減振效果的影響，結果表明：與普通巨型框架結構相比，減振結構通過合理選擇子結構剛度，可以較好的控制主結構在順風向脈動風作用下的位移響應，從而提高結構的安全性，但與此同時，子結構自身的加速度響應也有了一定程度的提高。Then, using the large - scale coarse grained soil test system, the relative density and direct shear characteristics of sand - gravel mixtures in different size distribution were tested. and the soc affecting mechanism derived from non - uniform granular material was discussed. the phenomenon can be observed that, along with the increase of non - uniform degree, the accumulate structure will become more complex, and the sliding resistance among sands will grow accordingly
在此基礎上，利用大型粗顆粒實驗系統，測定不同非均勻系數沙石材料的相對密度和直剪特性，探討了顆粒非均勻程度對自組織臨界性影響的具體物理力學機制：隨著非均勻度的增大，散粒堆積體的顆粒結構空間分佈堆積方式的多樣性增大，顆粒滑動的摩擦耗能增加。In the paper, the randomness in the constitution of the sliding mass, in the from of sliding and in the shear strength of the sliding surface is considered, the anti - slide reliability of one arch dam is analyzed, and satisfying results are obtained
