摘要:
为了研究尺寸效应对纤维增强复合材料（FRP）加固混凝土圆柱轴压性能的影响，在修正尺寸效应律公式的基础上，推导了反映尺寸效应的FRP加固混凝土圆柱的极限强度计算公式，提出了简化的应力应变模型，并与收集到的各国试验结果进行了比较。研究结果表明：模型计算结果与试验结果吻合较好；该模型能够反映尺寸效应对极限强度的影响。
Abstract:
In order to study size effect on the axial compressive behavior of circular concrete columns strengthened with fiber reinforced polymer (FRP), based on the equation of modified size effect law, the ultimate strength calculation formulae of circular concrete columns strengthened with FRP were deduced, which could reflect the effect of different columns sizes. Meanwhile, the simple stressstrain model was proposed, and the comparisons of experiment results and existing model calculation results were done. The study results show that the model calculation results are coincided with the experiment results, and the model can reflect the size effect on ultimate strength.
