摘要:Abstract(#br)This paper proposes a new approach for the formulation of compressive strength of carbon fiber reinforced plastic (CFRP) confined concrete cylinders using a promising variant of genetic programming (GP) namely, linear genetic programming (LGP). The LGP-based models a...

摘要:... The parameters studied include the amount and type of confinement at midspan (no confinement, internal steel stirrups or externally bonded carbon FRP), concrete cover and bar size. The results show that the CFRP confinement enhanced the bond strength of the lapped bars by up ...

摘要:Abstract(#br)Partial CFRP-confinement has been used as an option beside full CFRP-confinement for strengthening structural elements. However, the sufficiency of partial CFRP-confinement has always been uncertain. Therefore, this paper presents 24 specimen cylinders (300 mm ×...

摘要:Reinforced concrete (RC) columns are often placed under confinement to increase their strength and ductility. Carbon fiber reinforced polymer (CFRP) materials have recently been recognized as favorable confinement systems. At present, a number of national standards and codes dedi...
