摘要
将碳纤维布与钢板结合起来对钢筋混凝土梁进行加固,试验表明,该方法虽能使构件的承载能力和刚度都得到显著地提高,但对延性的削弱也不可忽视。基于复合加固梁的受力特征,提出加固梁截面曲率延性系数的计算方法,并讨论了其影响因素。
Reinforced concrete beams were strengthened with CFRP and steel-plate,experiment result shows this method can significantly raise the capacity and stiffness,but also reduce the ductility.Base on the behavior of mixed-strengthened beams,a calculation method of curvature ductility coefficient is proposed,and some key factor is discussed.
