摘　　要：本文依据多层仓顶室贮仓的自振特性,深入系统地分析了这类贮仓的“鞭击效应”。提出了对应层层间剪力放大系数的概念;明确了其计算条件。并指出:通过改变仓顶室各层的支承刚度或质量可以避开最强烈的“鞭击效应”。给出了两层仓顶室各层剪力放大系数的取值表格,以供抗震设计和验算参考。The whiplash cffcct of carthquakcs for storage structurcs with multistorcy attics is ana-lyzcd thoroughly and systematically with according to the behaviour of natural vibrationfor this style of storage structures. A conception or the magnification coefficient for shearforce corresponding to the storey is introduced, The research results indicated that the mostintensive whiplash cffect can be avoided by changing the stiffness or the mass of eachstorey. A table of magnification coefficient for shear force or each storey of the story otticstorage structures is proposed, which may be applied as reference to earthquake-proof de-sign and check.
