摘要
在FRP加固混凝土柱的分析和设计中,需要准确可靠的应力-应变关系模型。一般情况下,FRP约束混凝土的应力-应变关系模型可以分为两类:①应力-应变关系分析模型;②应力-应变关系设计模型。推导了目前预测精度最高的主动约束混凝土的强度模型,然后根据Lee等的部分研究成果,建立了FRP约束混凝土柱的应力-应变关系分析模型。通过与试验数据及其他应力-应变关系模型的对比可知,本文模型能够得到预测水平较高的结果。
The accurate and reliable stress-strain model is necessary in the process of analysis and design for FRP-confined concrete columns.The stress-strain models of columns wrapped by FRP composites generally fall into main categories:①analysis-oriented models and;②design-oriented models.This paper develops an analysis-oriented stress-strain model in which both a theoretical strength model for actively-confined concrete having best production performance is proposed and Lee's investigation serves herein.In comparison with test data and existing models,the proposed analysis-oriented stressstain model can provide accurate and satisfactory prediction.
