Efficiency of shear strengthening of RC beams with externally bonded FRP materials – State-of-the-art in the experimental tests
نویسندگان
چکیده
This paper presents a study of the shear capacity reinforced concrete (RC) beams strengthened in with externally bonded (EB) fiber polymer (FRP) composites, based on performance existing published tests. The main objective this is to create comprehensive overview different strengthening configurations and failure modes observed experimental In addition, influence following parameters efficiency has been analyzed: span depth ratio (a/d), steel transverse reinforcement (ρsw), strength (fck), size effect (d), longitudinal (ρsL), configurations, type FRP: sheets or laminates (CFRP, GFRP), FRP axial stiffness (AfEf).

15 صفحه اولFrp Composites for Shear Strengthening of Rc Beams
ABSTRACT Fiber Reinforced Polymer (FRP) composite systems can be used for shear strengthening of reinforced concrete (RC) members. The present study investigated the shear performance and the modes of failure of simply supported RC T-beams externally strengthened in shear with FRP composites. Two different FRP-based strengthening systems were investigated, namely, externally bonded FRP sheets a...

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Effect of Shear Resistance on Flexural Debonding Load-Carrying Capacity of RC Beams Strengthened with Externally Bonded FRP Composites
Debonding failure is the main failure mode in flexurally strengthened reinforced concrete beams by externally bonded or near surface mounted fibre reinforced polymer (FRP) composites. It is believed that FRP debonding will be initiated if the shear stress on the concrete-FRP interface reaches the tensile strength of concrete. However, it was found through experimental and analytical studies tha...
