Guidelines for the Design and Construction of Externally Bonded FRP Systems for Strengthening Existing Structures

Pre-Cracked Concrete Shear Strengthened with External CFRP Strips

In reinforced concrete design, there are situations where transfer of shear across a specific plane needs to be considered. Examples of such situation include corbels, bearing shoes, ledger beam bearing, and a host of connection between precast concrete elements. In this study, the shear transfer behavior of reinforced concrete is investigated experimentally by conducting test on 6 precracked p...

North American Design Guidelines for Concrete Reinforcement and Strengthening Using Frp: Principles, Applications, and Unresolved Issues

This paper reports on the North American state-of-the-art in the use of FRP composites in concrete structures. FRP bars have been used as the internal reinforcement in concrete members to replace conventional steel rebars for a host of reasons. The principles for design and construction have been established and proposed to industry by the American Concrete Institute (ACI). The fundamental prin...

Various Frp Strengthening Techniques for Retrofitting Concrete Structures

The need for repair and strengthening of deteriorated, damaged and substandard infrastructures has become an important challenge worldwide. The demand for increasingly heavier truck loads is forcing bridge owners to upgrade existing structures. In response to the growing need for concrete repair and rehabilitation, an experimental program was conducted to investigate the feasibility of using di...

Durability of the Bonding Performance of Frp-concrete Interface Externally Bonded with Frp Composite Sheet

The strengthening of concrete structures externally bonded with fiber reinforced polymer (FRP) sheet is increasingly being used for repair and rehabilitation of existing structures. This paper provides information in the area of long-term durability of FRP-concrete interface externally bonded with FRP composite sheet. It mainly discusses and summarizes the influence of harsh environmental expos...
