Abstract

Recently, reinforced concrete beams strengthened with carbon fiber reinforced polymers(CFRP) have been widespread. The objective of this research is to calculate the shear strength capacity increment of reinforced concrete beams strengthened by CFRP strips. The ABAQUS software was used to construct a model of the finite elements for beam simulation. Six beams were generated in ABAQUS software, two were control beams and the remaining four were reinforced by varying CFRP strips. All beams had the same rectangular cross-section geometry and length. The obtain results showed that CFRP can significantly increase the shear capacity of the beam. And the highest load and deflection is a little affected by the CFRP strips orientation. This study can proposes a more economical way for existing structures to improve the carrying capacity.

Abstract

In the bet of a circular economy to conserve, maintain and lengthen the value of water distribution and supply networks, infusion and vacuum technology used for on-site pipe manufacturing by means of carbon fiber is a safe, reliable and effective alternative for all of those pipelines, whose repair is a major challenge due to the complexity of action by traditional means. Excavations, interference with other services and social pressure exerted by excessive traffic cuts and supplies, are adversities that demand a cultural and strategic change towards the implementation of these innovative solutions, which are already a reality.
