This paper presents a study that forms part of an ongoing project on the seismic retrofit of reinforced concrete (RC) structures with fibre-reinforced polymer (FRP). In this study, a stress-strain model for FRP-confined concrete subjected to cyclic loading was implemented into OpenSees to support the performance-based design of FRP jackets for the seismic retrofit of RC columns/structures. Init...

Today, due to the complexity of engineering problems and at the same time the advancement of computer science, the use of machine learning (ML) methods and soft computing methods in solving engineering problems has been considered by many researchers. These methods can be used to find accurate estimates for problems in various scientific fields. This paper investigates the effectiveness of the ...

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...

Corrosion of steel reinforcement is one of the main durability problems facing reinforced concrete infrastructures worldwide. This paper will summarize the results of a multi-phase experimental program undertaken at the University of Waterloo to investigate the viability of using externally bonded fiber reinforced polymer (FRP) laminates to rehabilitate corrosion-damaged reinforced concrete bea...

the use of polymer composite (frp) as a reinforcement material for the repair and strengthening of important components of reinforced concrete structures, particularly columns, has found wide spread. in this study, the effect of intermediate layer on improving the confinement behavior of reinforced concrete columns has been investigated. to achieve the objectives of the study, 14 cylindrical re...

This paper focuses on the compressive strength of Glass fiber reinforced polymer (GFRP)-confined concrete columns. Data from 114 sets GFRP-confined columns were collected to evaluate researchers’ and proposed model. A data-driven machine learning model was used investigate importance sensitivity parameters affecting strength. The results show that facilitates study confined but suffers a large ...
