摘　　要：在试验分析的基础上,对拱式转换层结构建立了弹塑性有限元模型,由此对水平反复荷载作用下拱式转换层结构水平力—侧移滞回曲线进行了分析计算,结果和试验曲线基本相符,并且两者均表明该结构水平力—侧移滞回曲线呈梭形,结构延性耗能较好,因此只要合理设计,拱式转换层结构能够具有较好的延性与耗能。On the basis of experiment analysis,the analytic model of elastoplastic finite element was derived from arch transfer floor, and the hysteresis hoop of horizontal force-lateral deflection was analyzed for the arch transfer floor subjected to horizontal cyclic loading. The analytic results are in good agreement corresponding relatively with experiments, and it indicates that the hysteresis hoop of horizontal force-lateral deflection appears in a shuttle shape, and the ductility and energy consumption of the structure may be greater. Consequently, the arch transfer floor structure may possess higher ductility and energy consumption, if the structure is designed rationally.
