贮仓地震反应的非线性分析

Non-Linear Analysis on the Seismic Response of Bin

考虑贮仓在地震反应中的P-△效应和钢筋混凝土支承柱的刚度退化,对柱承式贮仓的地震反应进行了非线性分析。将地震加速度记录调整到8°、9°分别输入,用Wilson θ法逐步积分非线性微分方程,并作了大量计算与分析,提出了P-△效应的统计结果,对贮仓的抗震验算有重要参考价值。

Considering the P-Δ effect of bin in scismic response and the stiffness degeneration ofR. C. column, a non-linear analysis on the seismic respnse of the column-supported binhas been carried out in this paper. Inputting the seismic acceleration records adjusted to8° and 9° respectively, applying Wilson 0 method step by step integrated non-lineardifferential equation, and a large number of analysis and computation a statistcal result ofP-Δ effect was proposed, which is a worth while reference to check the scismic resistauceof bins.
