摘　　要：在对HPFL加固5根足尺RC轴心受压柱的二次受力试验研究的基础上,进行了有限元模拟分析,试验研究和有限元模拟分析均表明加固后的柱子承载力和刚度都得到了相应的提高,且在二次受力加载时,加固层均呈现应变滞后现象,通过对有限元分析结果和试验结果的比较,验证了所建立的有限元模型的正确性与合理性。Based on the research on the secondary load test of HPFL consolidated five full scales RC axial loaded column, the papr undertakes the finite element simulation analysis, indicates the improvement at the loading capacity and stiffness of columns after the consolidation in the experimental research and finite element simulation analysis, compares the analysis results and test results of the finite element analysis of the strain lag in the consolidation layer in the secondary stress loading, and proves the established finite element model is correct and reasonable.
