Fiber reinforced polymer (FRP) material is currently being produced in different configurations and widely used to strengthen and retrofit concrete structures and bridges. It is also possible to apply other strengthening methods without changing the appearance or the dimensions of the structure. Near Surface Mounted (NSM) is a recent strengthening method using CFRP bars (rods or laminate strips...

Scrap steel fiber concrete (SFRC) is a new kind of material, which uses the scrap from tire as reinforced FRP bar concrete, replacing or partially traditional and synthetic fiber. This paper summarizes research status waste at home abroad, including mechanical properties compressive tensile resistance, mixing amount use requirements fiber, finally development prospect forecasted

The use of bonded fiber reinforced polymer (FRP) sheets for upgrade or repair of aging and deteriorating concrete structure has emerged as a viable and cost effective method. Previous research has identified several items that influence FRP-concrete bond strength including concrete strength, type of FRP laminate, the number of layers of the FRP laminate, and the bonding agent or epoxy saturant ...

Today the rapid growth of fiber-reinforced polymer (FRP) applications in the automotive and aerospace industry has motivated many researches to perform life-cycle analyses of FRP structures. While its strength-to-weight ratio outperforms conventional metals, FRP is inherently heterogeneous and experiences complex failure modes, thus making them challenging for structural analysis and design. As...

Retrofits and reinforcements are needed in structures that have experienced a decline performance to continue meet their strength requirements. Reinforcement of reinforced concrete can use the method strengthening with Fiber Reinforced Polymer (FRP) which is made from synthetic fibers. But now there new innovation, namely FRP natural The fibers as basis for composite materials reduce negative i...

Abstract Fiber-reinforced polymer (FRP) has been commonly used to reinforce concrete structures. The kinds of FRP demonstrate an effective alternative various methods reinforcement in structures subjected bad environmental conditions which cause corrosion and damage concrete. Due their lightweight, high strength, fatigue resistance, Fiber Reinforced Polymer composites have widely applied steel ...

This paper presents several advancements in the use of fiber reinforced polymer (FRP) materials for the precast concrete industry. Precast concrete members are commonly selected for reasons such as the high level of quality control used in their production, the durability of the finished structure, reduced labor costs and shorter construction schedules, and the economics of scale achieved with ...

In moment resisting reinforced concrete framed buildings, corner joints are found at the roof level. These joints, if designed for gravity loads and are based on pre-seismic codes, may suffer substantial damage during earthquakes particularly under opening cycles, i.e. those causing flexural tension on the inside of the joint. Several techniques of repair and strengthening of reinforced concret...

This report presents the results of an experimental study that was conducted to investigate the effects of key parameters on the compressive behavior of fiber reinforced polymer (FRP)concrete-steel double-skin tubular columns (FSDT). Hybrid FSDT columns have been introduced as a new form of hybrid columns. They consist of an outer tube made of FRP and inner tube made of steel, with sandwiched c...

A Model to Predict the Long-Term Strength of E-Glass Fiber Composites Subjected to Environmental Exposure Thomas Miles Damiani Glass Fiber Reinforced Plastics (FRP) are being used in an increasing number of structures and machines because of their advantages over conventional materials such as steel or aluminum. However, sustained exposure to seemingly nominal service conditions can act to degr...
