Most of the standing structures today have already deteriorated or are on verge deterioration due to an increase in their age and harsh environmental conditions. For this very reason, need being upgraded replaced. Retrofitting using near-surface mounted (NSM) fiber-reinforced polymer (FRP) rods has now emerged as a promising technique for strengthening reinforced concrete members by increasing ...

Abstract—Various retrofit techniques for reinforced concrete frame with infill wall have been steadily developed. Among those techniques, strengthening methodology based on diagonal FRP strips (FRP bracings) has numerous advantages such as feasibility of implementing without interrupting the building under operation, reduction of cost and time, and easy application. Considering the safety of st...

Concrete is one of the materials that widely used in various structural works because it has advantages, especially high compressive strength and easy to form. However, concrete can also be damaged by physical, chemical, mechanical excessive loads. Damaged structures must repaired strengthened immediately prevent further damage lead failure. One for reinforcement Fiber Reinforced Polymer (FRP)....

Existing bond-slip (τ-s) relations for fibre-reinforced polymer (FRP)-steel joints employ different shapes and mathematical expressions, inferring that their predictions of failure load mode, other interface properties, might be inconsistent or inaccurate. In this study, four widely used τ-s are evaluated using a large experimental database 78 double-lap FRP-steel specimens. To facilitate the e...

Many researchers have shown that it is engineering feasible to use fiber-reinforced polymer (FRP) bars instead of steel as the tension-affected main in reinforced concrete structures. However, slabs strengthened with FRP are limited field civil engineering. For example, elastic modulus low, and ductility member reduced due brittleness bars. To solve these problems much possible, scholars adopte...
