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。
Based on the experimental analysis, an elasto-plastic finite element model is established for the arch transfer layer structure. The horizontal force-lateral displacement hysteretic curves of the arch transfer layer structure under horizontal repeated load are analyzed and calculated. Results and tests The curves agree well with each other and both show that the horizontal force-lateral hysteresis curve of the structure is fusiform and the structural ductility energy dissipation is better. Therefore, the dome structure can have good ductility and energy dissipation as long as the design is reasonable.
