摘　　要：装配式钢筋再生混凝土结构是再生混凝土应用于装配式建筑中的一种新型建筑结构体系,对结构进行抗震性能评估是结构安全分析的核心内容。为进一步评估装配式钢筋再生混凝土结构的抗震性能,文章采用Pushover分析方法,建立了基于结构整体超强系数概念的结构抗震性能评估方法,深度研究分析装配式钢筋再生混凝土结构安全储备能力。算例表明:结构在四级设防水准下全过程的抗震行为表现良好,满足装配式钢筋再生混凝土框架结构“小震不坏,中震可修,大震不倒”的抗震设防目标要求。Fabricated reinforced recycled concrete structure is a new type of building structure system in which recycled concrete is applied to prefabricated buildings.It is the core content of structural safety analysis to evaluate the seismic performance of the structure.In order to further evaluate the seismic performance of fabricated reinforced recycled concrete structures,this paper uses Pushover to establish a structural seismic performance evaluation depth study based on the concept of overall super-strength coefficient of the structure.Safety reserve capacity of fabricated reinforced recycled concrete structures The example shows that the whole seismic behavior of the structure is good under the four-level fortification level.The seismic fortification target requirement of prefabricated reinforced recycled concrete frame structure is“not bad in small earthquakes,repairable in medium earthquakes and not collapsed in large earthquakes”.
