Abstract

Abstract: The strength character is researched by 3-point bending experiments of reinforced concrete beams strengthened with continuous carbon fiber sheet with different parameters of carbon fiber sheet length, V-notch height of beams and ration of reinforcing steel bars. The debonding failure principium of interface is analyzed

Key words: carbon fiber sheet, concrete, debonding failure

摘要： 通过碳纤维薄板加固补强钢筋砼梁的抗弯试验，采用改变碳纤维薄板粘贴长度、梁的缺口高度和配筋率等参数，对加固梁的强度性能进行了较系统的试验研究，并初步分析了界面的剥离失效机理．
