ABSTRACT
This paper presents the results of experimental studies concerning the flexural strengthening of RC beams using externally bonded Slurry Infiltrated Mat CONcrete (SIMCON) laminates. A total of four reinforced concrete beams were cast and tested in the laboratory over an effective span of 3000 mm. Three beams were strengthened with bonded SIMCON laminate at the bottom under virgin condition and tested until failure; the remaining one beam was used as control specimen. Static responses of all the beams w ....etc

Reinforced concrete structures often have to face modification and improvement of their performance during their service life. The main contributing factors are change in their use of ,new design standards, deterioration due to corrosion in the steel caused by exposure to an aggressive environment and accident events such as earthquakes .In such circumstances there are two possible solutions: replacement or retrofitting.
Retrofitting of flexural concrete elements are traditionally accomplished by externally bonding steel plates to concrete whi ....etc

Fatigue Behavior of Reinforced Concrete Beams Strengthened with Different FRP Laminate Configurations
Synopsis: This paper presents testing results of thirteen small-scale beams
strengthened using carbon fiber-reinforced polymer composites tested under repeated
loads to investigate their fatigue behavior. The beams were strengthened using
different thicknesses and widths of composite laminates to identify parameters that
would generate different failure modes. Two predominant fatigue failure modes were
identified through these tes ....etc

INTRODUCTION
In the last 200 years, rapid advances in construction materials technology have enabled civil engineers to achieve impressive gains in the safety, economy, and functionality of structures built to serve the common needs of society. Through such gains, the health and standard of living of individuals are improved. The use of FIBRE REINFORCED POLYMERS (FRP) as reinforcement for structures is rapidly gaining appeal. Fiber reinforced polymer (FRP) systems are high-strength, lightweight reinforcement ....etc
