Abstract


Carbon fiber reinforced concrete structures is an emerging field of structural reinforcement method of structural reinforcement . However , the ways reinforced concrete beam members often stripped destruction phenomenon of the early strength of concrete is lower , the more prone to debonding . Because of the restrictions on the kinds of reinforcement in low strength concrete structures reinforcement , so we seek a reasonable additional anchoring CFRP reinforced widely used in low strength concrete structures reinforcement . This topic has produced four low-intensity (C15) concrete beams , the main study did not take additional anchorage reinforcement beams form of debonding , the focus on this paper, steel U -shaped hoop additional anchoring effect of the anti-stripping measures . Through the test results , the proposed bonding at the interface of concrete in finite element analysis , the first principal stress reaches the limit of its strength that debonding both stripped criterion . Finite element analysis of four reinforced concrete beams , with the test results of CFRP flexural reinforcement Reinforced Concrete beam finite element model of the experimental verification . Over compared with the experimental results , the finite element calculation with the experimental results agree well with that CFRP flexural strengthening beam finite element model established in the article is more reasonable . Steel U -shaped hoop anchorage mechanism deep - step analysis , numerical simulation of the 14 beams , according to the U-shaped hoop anchor position , width , spacing , anchoring way analysis of various factors CFPR performance reinforcement beams . The results show that : the use of steel U-shaped hoop anchor beams carrying capacity has increased, decreased the deflection , the location of the crack in the U-shaped hoop was significantly inhibited . U -shaped hoop side steel plate pass the external cracks dentate body of concrete between the shear stress, control the pace of development of the crack , bound by steel U -shaped hoop while the bottom of the concrete and the longitudinal carbon fiber to improve the interface of local stress concentration problems , reduced local principal tensile stress of the concrete unit the longitudinal fiber cloth role played prevent peeling . Different anchoring measures to produce the different anchoring effect, it is recommended that the shear spanned equidistantly arranged in the U-shaped hoop, and concentrated load are arranged at the U-shaped hoop .
