摘要
文章对碳纤维织物加固混凝土矩形柱进行了研究,通过5根试件的破坏性试验,总结出混凝土矩形柱不同加固率在二次加载模式下的破坏特征及抗压强度的变化规律,经过理论分析,建立了计算模型。
Using carbon fiber to strengthen the concrete rectangular columns is studied in this paper . By testing 5 columns, the failure properties and variety rules of the concrete rectangular columns with different strengthen ratio were summarized. A couple of the columns were twice loaded. At the same time, by theoretital analysis and deduced a reinforcement bearing capacity calculation formula.
