摘要
利用混凝土徐变模型进行分析并得出碳纤维布加固混凝土T形梁的徐变计算方法,分析持荷时问、 配碳纤维布率、混凝土强度的变化对加固梁的徐变特性的影响,以及加固的混凝土T形梁的碳纤维布、压区 混凝土的应变变化.
By means of a creep model that is proposed in this paper, a formula for calculating the creep of reinforced concrete T-section beams strengthened with CFRP, influenles of time under sustained loading, CFRP ratio and strength of the RC on the creep characteristics and the changes of strain of reinforced concrete T-section beams strengthened are analyzed.
