This study examines the behavior of circular concretes externally confined by green sustainable WHBR FRP containing water hyacinth fiber ropes and bio-resin. principally purposes to discover axial stress-strain relationship FRP-confined concrete. A total 10 with a dimension 150×300 mm were cast, strengthened one four layers FRP, tested under compression. The stress deformability observed be inc...

Reinforced concrete (RC) columns can be effectively rehabilitated or strengthened by externally bonded fiber-reinforced polymer (FRP) wraps, which improve the axial load capacity and ductility of these through a confinement effect. Modern design codes require that seismically designed RC have significant minimum amounts both longitudinal transverse steel. This steel apply considerable confining...

Standoff methods of non-destructive testing (NDT) offer flexibility over traditional methods of inspection which typically require physical contact with the material being measured. The benefits are that difficult to access locations can be inspected and measurements of a large area can be made more quickly. Acoustic-laser vibrometry is a robust standoff NDT technique for composite materials, s...

This study focuses on using an artificial neural network (ANN) based model for predicting the performance of high strength concrete (HSC) beams strengthened with surface mounted FRP laminates. Eight input parameters such as geometrical properties of the beam and mechanical properties of FRP laminates were considered for this study. Back propagation network with Lavenberg-Marquardt algorithm has...

This paper focuses on the effect of the viscoelasticity of the adhesive layer on the flexural creep response of reinforced concrete beams strengthened with composite materials. A theoretical model is developed, which considers the strengthened beam as a layered structure that consists of the reinforced concrete beam, the adhesive layer, and the FRP strip, and accounts for the creep of each comp...

In this research, three models of beam-column joint have analyzed under reversed cyclic loading by finite element method using ANSYS software. The first model was designed with a steel-reinforced (longitudinal reinforcement and stirrups), the second performed (GFRP) -reinforced in longitudinal only third (CFRP) only. behaviour loading, their load-storey drift envelope relationship energy dissip...

The near-surface-mounted (NSM) fiber-reinforced polymer (FRP) strengthening technique for reinforced-concrete (RC) beams has attracted worldwide research attention and application in the past two decades. In spite of improved bond strength between NSM FRP concrete, compared with externally bonded (EB) method, premature debonding failure still occurs, and, hence, efficiency intervention is limit...

Fiber Reinforced Polymer (FRP) composite is an attractive material for strengthening various civil infrastructures. The system that based on FRP composites consists of many elements. These are: (FRP), strengthened element (concrete, steel, wood, etc) and bonding agent. latter the most important elements which affect performance whole system. Different types agent are used service conditions. Ep...
