Fiber Reinforced Polymer (FRP) systems have gained much popularity as a method for reinforcing existing concrete structures. However a variety of sudden failure methods, such as debonding, delamination, and creep rupture have led to the development of code limitations on the strength that an FRP system can be considered to provide. The uncertainty brought on by the failure methods mentioned abo...

Failures in FRP-strengthened reinforced concrete (RC) members may occur by flexural failures of critical sections or by debonding of FRP plate from the RC beams. Debonding in the FRP/adhesive/concrete interface region may cause a significant decrease in member capacity leading to a premature failure of the system. There is a need for improved knowledge of the debonding processes under mechanica...

The current paper reviews existing design guidelines for strengthening beams in shear with carbon fibre reinforced polymer (CFRP) sheets and proposes a modification to Concrete Society Technical Report TR55. It goes on to present the results of an experimental programme which evaluated the contribution of CFRP sheets towards the shear strength of continuous reinforced concrete (RC) beams. A tot...

In aerospace and many types of civil infrastructure applications, the use of adhesive-bonded composite joints have been constantly increasing. In this study, fracture behaviour of adhesively bonded single lap joint (SLJ) with pre-existing damage at the interface of free edge of the top adherend and adhesive along the width of the joint is studied by strain energy release rate (SERR) approach us...

concrete shear walls are the most prevalent structural systems resisting lateral loads due to earthquakes in high-rise buildings. very large in-plane stiffness of shear walls provides an excellent drift control in the structure. however, structural damages and early code shortcomings threaten the efficiency of existing structural walls against earthquake. recently, fiber reinforced polymer (frp...

A wide range of materials and scaffolding fabrication methods for bone tissue engineering have beenexplored recently. Fiber reinforced polymers (FRP) system appears to be a suitable system. By the exclusiveuse of biocompatible or bio-absorbable polymers and fibers, novel generation of scaffolds for applicationsin tissue engineering can be prepared. Mulberry Silk as highlighted...

During recent years, the use of fiber-reinforced polymers (FRP) as a desirable alternative for improving the behavior of lateral resisting system are known. There are various factors influencing the quality of such kind of rehabilitation. This study aims to investigate the influence of geometric characteristics and arrangement of FRP layers on rehabilitating of concrete shear walls.  A few rein...

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...

The majority of columns are subjected to a combination of an axial load and a bending moment in one or two directions. With a few exceptions, most of the research in the area of FRP wrapped columns have concentrated on the behaviour of concentrically loaded columns. This paper presents results of testing nine reinforced high strength concrete columns. The column specimens are circular in shape ...

Restoring forces, which are generated when the left ventricle contracts below its equilibrium volume (Veq), are responsible for diastolic suction. Their magnitude is inversely related to end-systolic volume (ESV). In previous studies in which the mitral valve was replaced with a prosthesis, increased contractility was shown to augment restoring forces independently of ESV. In the present study,...
