In order to study the flexural performance of reinforced concrete beams strengthened with high-strength polyurethane composites (HSPUC), the static failure tests of two reinforced concrete beams strengthened by HSPUC reinforcement layer w
The beams were reinforced with two longitudinal bars. Shear reinforcement was provided by external means using steel collars. The results show marked reductions in flexural strength due to reinforcement corrosion, which is caused primarily by the breakdown of bond at the steel/concrete interface. 展开...
This article makes an experiment on the three point flexural strength of the concrete composite beams reinforced by the hybrid fiber grid fabrics. The curve is drawn to refect the relation between the pressure and the deflection of the two kinds of the beams.It shows from the experimental result...
An Experimental Study on Flexural Ductility of High Strength Concrete BeamsSenthilkumar, AnusuyaRaghunath, P. N.Suguna, K.IUP Journal of Structural Engineering
The purpose of this study is to investigate the flexural crack development of high-strength reinforced concrete (HSRC) beams and suggest the design equations of the flexural crack control for HSRC beams. This study conducts two full-size simply-supported beam specimens and seven full-size cantilever...
To evaluate the effect of elevated temperatures on flexural strength, the concrete beams strengthened with basalt fiber reinforced polymer (BFRP) and glass fiber reinforced polymer (GFRP) sheets in the presence of cement and epoxy adhesives and were subjected to temperatures of 50, 100, 200, and ...

Six high-strength concrete beam specimens reinforced with different types of flexural reinforcement were constructed and tested. All beam specimens consisted of two layers of flexural reinforcements. Three types of conventional steel bars, CFRP bars, and
Flexural Behavior of Reinforced Concrete Beams Strengthened with Carbon Fiber-Reinforced Polymer Laminates at Different Levels of Sustaining Load To examine the effect of sustaining load at strengthening on the flexural behavior of strengthened reinforced concrete beams, six beams strengthened with c... ...
Design codes specify minimum flexural reinforcement for reinforced concrete beams. With the extensive use of higher strength concrete, the empirical expressions of the past for minimum flexural reinforcement, in which the concrete strength is not considered, had to be revised. Six reinforced concrete T...
