Abstract: 

1. INTRODUCTION: IN THIS PAPER A STATE-OF-THE-ART REPORT ON THE EXTERNALLY APPLIED FIBER-REINFORCED POLYMER (FRP) COMPOSITE MATERIALS IN RETROFITTING AND STRENGTHENING OF REINFORCED CONCRETE STRUCTURES IS PRESENTED. STRENGTHENING METHOD USING FRP SHEETS CAN BE DONE MANUALLY WITHOUT HEAVY EQUIPMENT. THE MAIN CHARACTERISTICS OF THE RETROFITTING METHOD USING FRP FOR CONSTRUCTION ARE: GOOD CONSTRUCTION WORKABILITY; SHORTER CONSTRUCTION PERIOD, HIGHER DESIGN FLEXIBILITY, LESS TOTAL COST (INCLUDING CONSTRUCTION CONDITIONS AND TIME) THAN WHEN USING STEEL JACKETING; AND THE PROJECT CAN BE EXECUTED WHILE THE STRUCTURE IS BEING USED. IN ADDITION, OTHER BENEFITS INCLUDE: ANY INCREASE IN STRUCTURAL WEIGHT DUE TO ADDING OF FRP IS SO SLIGHT THAT IT CAN BE IGNORED IN DESIGN; THERE IS NO ADVERSE EFFECT ON THE STIFFNESS OF STRUCTURAL MEMBERS IN CASE OF SHEAR STRENGTHENING; AND GREATER DURABILITY OF WRAPPED MEMBERS.
