The shear strength of fiber-reinforced polymer (FRP) reinforced concrete beams is often given a large safety margin by current construction requirements. Six characteristics are utilized as inputs to compute the FRP-reinforced beams. This study uses 198 samples from literature predict 139 training and 59 testing samples. Additionally, ANN structure optimized with firefly algorithm. FA-ANN model...

In this paper, the advances of finite element methods and analyses for FRP reinforced and strengthened concrete beams in last two decades are reviewed to present a state of the art of the research of numerical analysis and modelling of FRP composite concrete beams. Future research on finite element analysis of FRP composite beams is also presented.

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...

Strengthening of reinforced concrete structures using FRP has emerged as a potential solution to the problems associated with civil infrastructure. Many researchers have reported significant increases in strength and stiffness of concrete structures strengthened with FRP. Nevertheless, possible brittle failures of the strengthened system due to delamination of the FRP strips and/or sheets could...

Abstract Fiber Reinforced Polymer (FRP) usage to wrap reinforced concrete (RC) structures has become a popular technology. Most studies about RC columns wrapped with FRP in literature ignored the internal steel reinforcement. This paper aims develop model for axial compressive strength and strain confined The impact of FRP, Transverse, longitudinal reinforcement is studied. Two non-destructive ...

The use of synthetic Fiber Reinforced Polymer (FRP) as a composite material is an alternative that has been widely used for strengthening and repairing reinforced concrete structures. However, the high price one obstacles in applying FRP materials developing countries such Indonesia. Utilization natural fiber Natural (NFRP) alternative, especially shear beams. Because it good tensile strength a...

The use of externally bonded fiber-reinforced polymer (EB-FRP) composites for shear strengthening reinforced concrete (RC) beams presents many challenges given the complex phenomena that come into play. Premature bond failure, behavior interface layer between FRP and substrate, brittle nature cracks, adverse interaction internal steel stirrups EB-FRP are some these phenomena. Compared to experi...

A large share of reinforced concrete (RC) framed buildings is provided with wide beams being a type of beam allowing greater freedom in the architectural arrangement of interiors, beyond further advantage due to fewer formworks needed during the construction. Nevertheless, little attention has been devoted to the seismic vulnerability of this kind of framed RC buildings as well as to the study ...
