The use of composite materials for strengthening the ailing infrastructure has steadily gained acceptance and market share. Employing composite materials in strengthening of steel structures is the subject of this study. There are several challenges that face strengthening steel structures using composite materials. The superior mechanical properties of steel result in a reduction in the effici...

As part of a larger project to investigate the use of Fiber-Reinforced Polymer (FRP) materials in bridge construction, a short-span FRP-reinforced concrete bridge was installed in central Missouri. The Walters Street Bridge is a precast concrete panel bridge reinforced with both glass FRP (GFRP) and carbon FRP (CFRP) reinforcing bars. It was designed according to the American Concrete Institute...

The paper discusses the results of an experimental investigation carried out on reinforced concrete (RC) beams strengthened in shear by externally bonded fiber reinforced plastic (FRP) sheets. The study is devoted to analyze the role that the transverse steel reinforcement and the beam slenderness ratio could play on the resistant mechanism of RC beams strengthened in shear by FRP composites. T...

This paper highlights the philosophy and concepts used for of the design of prestressed concrete structures prestressed by fibre reinforced polymer (FRP) tendons and rods proposed for the Canadian Standards Association (CSA) S806-00 Standard "Design and Construction of Building Components with Fibre Reinforced Polymers". The paper deals with the section of the code which applies to concrete bea...

Corrosion of steel reinforcement is one of the main durability problems facing reinforced concrete infrastructures worldwide. This paper will summarize the results of a multi-phase experimental program undertaken at the University of Waterloo to investigate the viability of using externally bonded fiber reinforced polymer (FRP) laminates to rehabilitate corrosion-damaged reinforced concrete bea...

Several building codes are available for the design of concrete structures reinforced with FRP; nevertheless knowledge on their structural behavior in case of fire is lack and no reliable design method is available. The experimental data available in the literature about the behavior of fiber-reinforced composite materials as well as of concrete slabs reinforced with FRP bars or grids at high t...

As the life age of the existing structures are required to meet the changing demands on civil infrastructures. So strengthening and retrofitting are required. Recently many techniques to strengthen the reinforced concrete beams in flexural by using fiber reinforced polymer (FRP) had appeared. The most famous technique among them is strengthening the (RC) beams with externally bonded FRP sheet t...

Debonding failure is the main failure mode in flexurally strengthened reinforced concrete beams by externally bonded or near surface mounted fibre reinforced polymer (FRP) composites. It is believed that FRP debonding will be initiated if the shear stress on the concrete-FRP interface reaches the tensile strength of concrete. However, it was found through experimental and analytical studies tha...

This paper numerically investigates the flexural response of concrete beams reinforced with steel and four types Fiber-Reinforced Polymers (FRP), i.e., Carbon FRP (CFRP), Glass (GFRP), Aramid (AFRP), Basalt (BFRP). The responses forty two boundary conditions (simply supported over-hanging beams) were determined using ABAQUS. Subsequently, finite element models validated experimental results. Ev...
