摘要
通过模型试验研究,重点讨论了初始应力水平指标对加固柱性能的影响;提出了考虑应力水平指标和外包混凝土对核心混凝土约束作用的承载力计算方法,计算结果与试验结果吻合较好。
Based on the study of model experiment on RC columns strengthened with enclosed reinforced concrete,while the initial stress level index is described as the focal point in this paper,a calculation method of load-carrying capacity with the consideration of stress level index and confinement by the enclosed concrete to the core concrete is presented.The calculation results come with a good agreement with the measured data.
