摘　　要：利用有限元程序SAP91对864个钢筋混凝土筒承式群仓计算模型进行自振特性的计算,分析钢筋混凝土筒承式群仓平动自振基频的各种影响因素,如:联仓数、筒体高径比、支承筒开洞率及开洞方向、装料程度等,并回归群仓自振基频的简化计算公式。The natural vibration characteristics of group-silos can be obtained by utilizing finite element method. The regress formula of the fundamental frequency of vibration can be gained by analyzing the calculation, and the formula embodies the influencing factors such as silos number, height-diameter ratio H / D , opening extent ξ and so on.
