摘　　要：目的为了进行非线性有限元分析并验证构件的抗震效果,提出配有高强钢筋的高强混凝土柱的恢复力模型.方法根据混凝土构件恢复力模型的基本理论和确定方法,针对高强钢筋高强混凝土柱的特点,考虑其刚度退化和强度退化,采用基于截面条带法的数值分析方法.结果配有高强钢筋的高强混凝土柱的恢复力特性不仅与钢筋和混凝土的材料性能有关,而且与配筋方式、数量和轴压比的诸多因素有关.结论提出的恢复力模型-退化双线性模型的正确性得到了实验的验证.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 by the reinforced concrete (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 reinforcing bar and its stiffness and strength degradation. The strip numerical method is adapted to analyze 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 reinforcing bar is not only relevant to the material performance of reinforcement and concrete but to the pattern and number of reinforcement and axial compressive ratio, this article draws the conclusion that the model is validated efficiently by comparing the results of test and numerical analysis.
