STUDY OF EARTHQUAKE ACTION AND TESTS OF MULTI-SILO SUPPORTED BY CYLINDER
-
摘要: 通过模型试验及计算机分析,对钢筋混凝土筒承式群仓的自振特性及地震作用进行了研究,分析其变化规律和影响因素。提出了筒承式群仓平动自振基频、结构基本振型指数的计算公式及简化设计方法。Abstract: The simplified and practical calculation of multi|silo supported by cylinder is given, and it is discussed the changing law and influence factors, which are based on the study of the natural vibration characteristics and earthquake action by model test and computer analysis.The calculating formulae and short_cut methods for design, which are about the basic frequency of vibration,and the structural coefficient of the basic vibration model, are put forward.
