本文在总结前人研究成果的基础上，新的双-本文根据钢筋混凝土构件的基本理论和分析方法，建立了高强钢筋混凝土柱的线性退化恢复力模型，该模型考虑了高强钢筋混凝土柱的受力性能研究了高强钢筋高强混凝土柱的回弹特性及其刚度和强度退化问题。采用条带数值法对一个既可进行数值分析又可进行室内试验的高强钢筋高强混凝土柱进行了分析。在此基础上，提出了高强钢筋高强混凝土柱的回弹模型不仅与钢筋和混凝土的材料性能有关，而且与试验结果有关。最后，对高强钢筋高强混凝土柱的回弹模型进行了分析，并提出了高强钢筋高强混凝土柱的回弹模型以及配筋数和轴压比等因素，通过试验结果与数值分析结果的对比，表明该模型是有效的。
This article aims to establish a new bi-linear degradation resilience model for the high strength concrete columns installed with high strength reinforcement.On the basis of summing up previous research results,a new bi-linear degradation resilience model for the high strength concrete columns installed with high strength reinforcement is set up in the paper by the RC member basic theory and analysis method.The model is used by thinking of the performance of high strength concrete column reinforced with high strength rebar and its stiffness and strength degradation.The strip numerical method is adapted to analysis the column that is designed for both numerical analysis and test in the laboratory.Based on the result that the resilience model of high strength concrete column reinforced with high strength rebar is not only relevant to the material performance of reinforcement and concrete but to the paten and number reinforcement and axial compressive ratio et al.,this article draws the conclusion that the model is validated efficiently by comparing the results of test and numerical analysis.
