RC Columns Strengthened with Novel CFRP Systems: An Experimental Study

Experimental Study on Structural Degradation of CFRP Strengthened RC Beams Subjected to Weak Interfaces

Abstract: The performance of corroded reinforced concrete (RC) beams strengthened with externally bonded carbon fiber reinforced polymer (CFRP) materials may be affected by a weak interface caused either by defective bonding between the new and old concrete in the case of cover replacement or by expansive cracks in the case of direct application. To investigate this effect, thirteen strengthene...

Behavior Comparison of Uniaxial Cylindrical Columns Strengthened with CFRP

In recent years application of CFRP sheets in the strengthening of the concrete circular column has increased numerously. Knowing the exact behavior of concrete cylindrical columns confined with CFRP is of the first order of importance. ISIS Code of Canada has given relations for strength increase of circular columns confined with CFRP sheets, these relations are defined for a specified range o...

Experimental and Numerical Investigation of Two Fixed-End RC Beams Strengthened With CFRP Bars in NSM Method

Fiber reinforced polymer (FRP) material is currently being produced in different configurations and widely used to strengthen and retrofit concrete structures and bridges. It is also possible to apply other strengthening methods without changing the appearance or the dimensions of the structure. Near Surface Mounted (NSM) is a recent strengthening method using CFRP bars (rods or laminate strips...
