摘 要: 采用有限元方法对纤维增强复合材料(FRP)布加固框架节点进行数值模拟,提出一种能够有效地提高框架节点性能的加固方法,通过节点处梁柱受拉面上FRP布粘贴长度、FRP布弹性模量、FRP布粘贴层数的分析,得出一些规律性的认识。 The behavior of the RC frame beam-column joints strengthened with FRP is studied in the paper.The finite element method is used in the study.This paper presents a efficiency strengthening method which can enhance the behavior of the beam-column joints.In addition,The length、the elastic modulus and the mumber of layer of FRP fabric glued on the beam-column joints is discussed based on the numerical results,Some useful conclusions are obtained through the study.
