贮仓与贮料相互作用的试验与计算分析

通过地震反应试验和计算两种方式对贮仓与贮料相互作用进行了探讨。首先根据在动力作用下贮料沿仓高的动压力分布曲线与仓体加速度的分布关系定性地证明了贮料与仓体之间存在着相互作用，这种相互作用起到了耗能作用。其次利用大型非线性有限元动力分析程序，考虑贮料的非线性特性进行了模拟地震反应分析，计算结果表明，贮料与仓体之间存在着运动相位差，进一步证明了两者之间存在着相互作用。

TESTING AND CALCULATION ANALYSIS OF INTERACTION BETWEEN SHO AND STORED MATERIAL

The interaction between a silo and stored material is investigated by means of seismic response test and calculations. First, the interaction between the stored material and the silo body has been proved qualitatively according to the relationship between the dynamic pressure distribution of the stored material along the height of the silo and the distribution of the silo body acceleration under the action of dynamic forces, and such interaction can dissipate energy.Secondly, a seismic response analysis of simulation has been conducted through a large dynamic analysis program of non linear finite element, taking account of the non linear characteristics of the stored material.The results indicate that there is a moving phase difference between the stored material and the silo body, which has shown further interaction between the two.
