摘要
通过2个碳纤维布加固钢筋混凝土框架梁和1个未加固框架梁的对比试验,分析了低周反复荷载作用下碳纤维布加固框架梁的加固效果,提出了加固梁的正截面承载力计算方法。
Reinforced concrete structures strengthened with carbon fiber sheets(CFSs) were studied world widely in the past few years. But at present, the researches on R.C. beams strengthened with CFSs only focus on the simplesupporting beams under monotonic loading,the mechanical properties of R.C. frame beams strengthened with CFSs under cyclic loading have been less studied. In this paper, two R.C. frame beams strengthened with CFSs and one unstrengthened R.C. frame beam have been tested under cycle loading. The increasing of loadcarrying capacity of strengthened beams is checked and analyzed. The formula for estimating the momentresisting capacity of R.C. frame beams with CFSs are proposed.
