摘要: The effectiveness of externally bonded strengthening for reinforced concrete (RC) elements strongly depends on the bond between material and mechanical properties cover. In this paper fiber cementitious matrix (FRCM) materials made out a poliparafenilenbenzobisoxazole (PBO) net embedded in cement based is experimentally analyzed. Experimental results double shear tests involving different lengths fibers cross sections are presented. allow to estimate effective anchorage length evidence that debonding occurs at fibers/matrix interface after considerable slip. They also confirms FRCM as external reinforcements concrete. obtained experimental can be used calibrate local bond-slip relation design reinforcement.
