摘要
在确定钢材与核心再生混凝土本构关系模型的基础上,采用数值方法对钢管再生混凝土轴心受压、纯弯曲和压弯构件的荷载-变形全过程关系曲线进行模拟,对此类构件的力学性能进行研究,理论分析结果与试验结果非常吻合。最后在参数分析结果的基础上,提出钢管再生混凝土压弯构件承载力的简化计算公式。
Based on the constitutive models of steel and core recycled aggregate concrete （RAC）, the load versus deformation curves of RACFST stub columns, beams and beam-columns were calculated using numerical method, and the calculated results agreed well with the tested results. Finally, based on the results of parametric analysis, simplified formulae for the calculation of bearing capacity of RACFST members were proposed.
