plastic hinge rotation capacity of reinforced concrete beams
a parametric study is performed to assess the influence of the tension reinforcement index, ( ω = ρ fy /f bc), and the bending moment distribution (loading type) on the ultimate deformation characteristics of reinforced concrete (rc) beams. the analytical results for 15 simply supported beams with different amounts of tension reinforcement ratio under three different loading conditions are pres...
متن کاملStrengthening of RC Beams Containing Large Opening at Flexure with CFRP laminates
This paper presents the study of strengthening R/C beams with large circular and square opening located at flexure zone by Carbon Fiber Reinforced Polymer (CFRP) laminates. A total of five beams were tested to failure under four point loading to investigate the structural behavior including crack patterns, failure mode, ultimate load and load deflection behaviour. Test results show that large o...
متن کاملFlexural Behavior of Reinforced HPFRCC Beams
High Performance Fiber Reinforced Cementitious Composite (HPFRCC) materials exhibit strain hardening behavior with multiple cracking under tensile loading. In this paper, experimental and parametric studies are performed to assess the influence of using HPFRCC material instead of normal concrete in reinforced concrete beams. After calibrating the experimental results, the analytical results inc...

متن کاملrepair effectiveness of cfrp and steel plates in rc beams with web opening: effect of plate thickness
the effect of steel plate thickness on the repair effectiveness of rc beam is presented in this paper. a total of four beams were tested, one beam repaired by cfrp with a thickness of 1.2 mm and used as a control beam, and three beams repaired by a steel plate. steel plates with a thickness of 2 mm, 3 mm, and 4 mm were used in repairing the beams. the maximum load-carrying capacity, deflection ...
