“…RC members and joints strengthened with BFRP and CFRP sheets were tested in the same manner to provide comparable results and to investigate the efficiency of BFRP strengthening systems [43][44][45]. As a part of this research program, an experimental study was conducted to investigate the seismic behavior of RC columns retrofitted with BFRP and CFRP sheets.…”

“…The usage of BFRP bar appears to solve this problem. In such bridges, BFRP bar can replace steel bar and is used as the forced steel bar [20][21][22] . BFRP bar has good corrosion resistance, high tensile strength, less density, which can not only solve the corrosion problem of steel bar, but also reduce the dead weight of the structure, and enhance the tensile properties of the structure.…”

Basalt Fiber Reinforced Polymer (BFRP) bar was deemed as a substitute material of steel bar owing to its strong tensile properties and corrosion resistance which is benefit to enhance the durability of reinforced concrete bridges. Based on the current research findings, the prospects of BFRP bar for the application to bridges were analyzed. It was concluded that BFRP bar had more widely application to bridges than steel bar owing to the advantages of BFRP bar in the mechanical performance of resisting the corrosion. Meanwhile, two key points of whether BFRP bar could be successfully applied to bridges were also discussed, i.e., the bond-anchorage properties between BFRP bar and concrete as well as the manufacturing technique of anchorage device of BFRP bar.

“…The compressive stress-strain relationship for concrete model was obtained by using the following equations to compute the multilinear isotropic stress-strain curve for the concrete. [22]: (10) where, c σ --compressive strength of concrete, N/mm 2 ; c ε --compressive strain at concrete section's upper margin; 0 ε --concrete compressive strain at the ultimate compressive strength c f ; n --coefficient, n=2. Internal reinforcement bars were modeled using 3-D spar elements (Link 8) and these elements allowed the elastic-plastic response of the reinforcing bars.…”

“…However, the study and application of the BFRP sheets in civil engineering are relatively new. Only Chen Xujun [9], Lin Jianting [10], Sun Yanying [11], Ou Yangyu [12] conducted experimental study on flexural behavior of reinforced concrete beams strengthened with BFRP sheets. It showed that the flexural behavior of the reinforced concrete beam increased greatly after strengthening with BFRP sheets.…”

This paper presented the results of testing reinforced concrete beams strengthening with the BFRP sheets. Five specimens were cast and tested. All specimens were 2600 mm total span with a cross section of 150mm width and 250mm depth. Out of the specimens, two specimens were designed as reference specimens. The rest specimens were repaired with the BFRP sheets. The variables examine in the experiment were the longitudinal tensile reinforcement ratio, the different layers of the BFRP sheets and the anchoring measures of BFRP sheets. All specimens were tested under simply supported condition. 3D nonlinear finite element (FE) numerical models by ANSYS10.0 software were conducted to accurately predict the ultimate bearing capacity and response of reinforced concrete specimens strengthening with BFRP sheets subjected to four-point bending loading. The nonlinear constitutive material properties of concrete and steel reinforcement were considered in the finite element model. The results of the FEM simulation were compared with that of the experimental specimens. The results showed that it was significantly effective for the flexural capacity of the BFRP sheet-bonded reinforcement in tensile zone for reinforced concrete beams. Moreover, it implied excellent results on the stiffness of the reinforced concrete beams. The flexural strength enhancement of the reinforced concrete beams strengthening with the BFRP sheets varied between 19% ~ 44% over the control beam. This study further identified that the BFRP sheet technique significantly enhanced the stiffness and flexural capacity of reinforced concrete beams.
