Abstract

Changing social needs, upgrading of design standards, increasing safety requirements and deterioration are some of the reasons that make the existing reinforced concrete structure ( such as bridges and buildings) need to be strengthened or repaired . Over the past several years, there has been a concerned research efforts to explore the strengthening effect of Carbon Fiber Reinforced Polymer (CFRP) laminates applied to reinforced concrete columns under centric loading . So, the main objective of this work is to identify the main parameters affecting the mechanical behavior of confined rectangular R.C. columns such as the confinement level and rectangularity ratio (t/b ratio) . The efficiency of externally bonded CFRP of rectangular R.C. columns is declared and evaluated . [1,2,3].
