Fiber-reinforced polymer (FRP) is the most promising technique in present era to bring sustainability, reliability, and pseudo ductility concrete structures due its superior properties. Thermoplastic thermoset polymers are thrown-out synthetic waste that contributes environmental pollution for a long time. Knowing this issue an attempt was made use High-Density Polyethylene Fiber (HDPE) fillers...
1 Strength, durability and health monitoring aspects of composite overlays on civil engineering structures are discussed. The perspective and benefits of the repair, upgrade, retrofit, and rehabilitation of US civil infrastructure using composite overlays is briefly reviewed. Bond strength, durability, and in-service health monitoring are identified as critical issues blocking the wide acceptan...
This paper reviews the reality and vision of the use of fiber reinforced polymer (FRP) composite materials in civil engineering and transportation infrastructure applications. Due to their superior characteristics these materials have become a commonly accepted construction material for both new construction and for rehabilitation and strengthening of existing bridges and structures. This paper...
There have been extensive efforts aiming at standardization of a test method for characterizing fatigue fracture propagation in FRP composites under tensile opening Mode I loads. These efforts, however, not yielded validated standard procedure yet. The effects experimental scatter, fiber bridging, and the two-dimensional delamination planar or shell-like structural components versus that beam-l...
. this paper presents the results of an experimental investigation on shear strength enhancement of reinforced concrete deep beams externally reinforced with fiber reinforced polymer (frp) composites. a total of six deep beam specimens of two different classes, as-built (unstrengthened) and retrofitted were tested in the experimental evaluation program. two composite systems namely carbon/epoxy...

The research described in this paper is dedicated to the use of continuous fibers as reinforcement for additive manufacturing, particularly using Shotcrete. Composites and particular fiber reinforced polymers (FRP) are increasingly present concrete reinforcement. Their corrosion resistance, high tensile strength, low weight, flexibility offer an interesting alternative conventional steel reinfo...

Beam-column joints (BCJs) constructed until the 1970s carry a low shear capability due to absence of reinforcement. Fiber-reinforced polymers (FRP) are more reliable than other materials strengthen weak BCJ. To date, plenty analytical models have been developed analyze actual contribution FRP strength RC BCJs. However, either too complex in computational efforts or based on empirical coefficien...
Earthquake that occurred within a period of several years may be caused reinforced concrete column fails to maintain its performance. Reinforcement methods improve the quality in resisting earthquake loads are needed. Strengthening with external restraints is expected increase strength concrete. The use synthetic Fiber Reinforced Polymer (FRP) as composite material for restraint on structures o...
