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...

Environmental awareness and the need for sustainable construction inspired researchers practitioners to explore innovative alternatives that might reduce greenhouse gas emissions energy use related excessive structural work. One such alternative is utilization of Fiber-Reinforced Polymer (FRP) bars as a reinforcement in reinforced concrete members. FRP possess favorable characteristics like hig...

Concrete has become one of the most widely used structural materials in civil engineering [...]

Recently, the need to increase the strength of reinforced concrete members has become a subject that civil engineers are interested in tackling. Of the many proposed solutions, fiber-reinforced polymer (FRP) materials have attracted attention due to their superior properties, such as high strength-to-weight ratio, high energy absorption and excellent corrosion resistance. FRP wrapping of concre...

S Jacketing technology using fiber reinforced polymer (FRP) composites is being applied for seismic retrofit and rehabilitation of reinforced concrete (RC) columns designed and constructed under older specifications. In this study, the authors develop an electromagnetic (EM) imaging technology for detecting such damage as voids and debonding between the jacket and the column, which may signific...

An increasing interest in the preservation of historic structures has produced a need for new methods for reinforcing curved masonry structures, such as arches and vaults. These structures are generally very ancient, have geometries and materials which are poorly defined and have been exposed to long-term historical movements and actions. Consequently, they are often in need of repair or reinfo...

Application of fiber-reinforced polymer (FRP) reinforcement in concrete beams may cause large deflection and crack width, as well low shear capacity ductility due to relatively small stiffness FRP materials. To avoid these unfavorable factors evaluate the behavior FRP-reinforced structural members, a high-performance strain-hardening cementitious composite (SHCC) is introduced substitute conven...

Wet filament winding technology has been extensively used for the manufacture of rotationally symmetric parts made fiber-reinforced plastics (FRP). As design and modeling FRP-parts require numerous assumptions, deviations between calculated achieved mechanical properties are expected. One aspect that contributes to this discrepancy is assumption a homogeneous rectangular cross-section fiber-ban...

This study provides combined experimental and numerical findings for a novel use of 3D Fiber Reinforced Polymer (FRP) fabrics as reinforcements in concrete beams. Experiments demonstrate that beams reinforced with the multidirectional FRP not only possess adequate strength ductility, but also have great potential to achieve low-impact structures. In this study, MATLAB-based code has been develo...

This paper describes an experimental program that deals with retrofitting of infill un-reinforced masonry walls (URM) with Fiber Reinforced Polymer (FRP). The primary objective of this research is to develop a retrofit strategy that while economical will minimize the influence of the retrofit on the overall performance of structural frames in predominant seismic regions. Allowing some damage to...
