摘　　要：计算配筋钢管再生混凝土外钢管及再生混凝土的热工参数和再生粗骨料取代率,利用有限元模型对高温下外钢管及再生混凝土本构关系进行数值模拟和试验分析。结合高温下耐高温试验研究配筋率、含钢率、荷载比等对配筋钢管再生混凝土柱承载力的影响,得到了配筋率的最优值。In this paper, the thermal parameters of recycled concrete and recycled concrete and the replacement rate of recycled aggregate concrete are calculated. The finite element model is used to simulate the constitutive relation of outer steel tube and recycled concrete under high temperature. Combined with a high temperature fire resistance test explores the reinforcement, including the impact of steel ratio, load bearing capacity of reinforced steel ratio of recycled concrete columns and reasonable reinforcement ratio.
