Abstract This paper presents the results of an experimental study on employing near surface mounted (NSM) fiber-reinforced polymer (FRP) reinforcement technique, and L?shape ribbed bars, for flexural strengthening lightweight reinforced concrete (RC) beams. 18 RC beams including 14 four normal-weight were designed. The strengthened with glass (GFRP) bars carbon (CFRP) laminate in bending tests....

Interlaminar failure of bonded composite structures is quite often. Nowadays there a lot lightweight high reliability carbon or glass fiber (CFRP GFRP) reinforced polymer constructions with rods. In order to better understand the delamination processes rods, analytical equations were analyzed. Later, mode I interlaminar experiments CFRP rods 3x3 mm performed and fracture toughness GIC = 135 J/m...

ABSTRACT Fiber Reinforced Polymer (FRP) composite systems can be used for shear strengthening of reinforced concrete (RC) members. The present study investigated the shear performance and the modes of failure of simply supported RC T-beams externally strengthened in shear with FRP composites. Two different FRP-based strengthening systems were investigated, namely, externally bonded FRP sheets a...

Fiber-reinforced polymer (FRP) rods are advanced composite materials with high strength, light weight, non-corrosive properties, and superior durability properties. Under severe environmental conditions, for concrete structures, the use of glass-fiber-reinforced (GFRP) is a cost-effective alternative to traditional steel reinforcement. This study compared flexural behavior an OPC slab high-volu...

Bond-slip behaviour of glass fiber-reinforced polymer (GFRP) bars embedded in conventional concrete has been widely investigated. In contrast, the bond-slip near-surface mounted (NSM) GFRP bonded reinforced recycled aggregate (RAC) seems to be less explored, while materials have increasingly used due reasons environmental pollution and resource exhaustion. This study aimed experimentally theore...

This paper presents a method of analysis for the response of concrete beams reinforced with fibrereinforced-plastic (FRP) tension rods and aramid spirals. Three different kinds of longitudinal reinforcement are adopted; CFRP, AFRP and GFRP. Both under-reinforced and over-reinforced sections are described. It is found that the ratio of neutral axis depth and effective depth can be used as an ind...

ABSTRACT: This paper explores the behavior of infill masonry structures strengthened with a new type of Fiber Reinforced Polymer (FRP) strengthening system with high fracture strain know as PET (Polyethylene Teraphthalate) and a new near-surface mounted (NSM) Carbon fiber strengthening system using a cementitious material as the adhesive as compared to a Glass Fiber (GFRP) strengthening system ...

An assembled plane truss structure used for vehicle loading is designed and manufactured. In the truss, the glass fiber reinforced polymer (GFRP) tube and the steel joint are connected by a new technology featuring a pretightened tooth connection. The detailed description for the rod and node design is introduced in this paper, and a typical truss panel is fabricated. Under natural conditions, ...
