ANALYSIS OF FREQUENT EARTHQUAKE RESPONSE OF ARCH TRANSFER FLOOR STRUCTURE
-
摘要: 拱式转换层是一种新型结构形式,由于转换层上、下部刚度突变,引起了该结构地震剧烈反应,本文针对这种新型转换层形式,分析了上、下部等效侧向刚度比对多遇地震反应的影响,进而提出设计建议,以供工程设计参考。Abstract: The arch transfer floor may be a new type of transfer story structure. As a result of the sudden change of rigidity of superstructure and substructure,the earthquake response may be considerably sharp.The effect of the equivalent lateral rigidity ratio on frequent earthquake response is analyzed in this new transfer floor,and some design proposals are presented,which can be referred in the design of engineering.
