The current research includes practical results of study and investigated the subject of strengthening the shear strength through uniaxial confinement (one direction) using GFRP Sheets. This study was carried out by casting eight specimens (the push-off specimens group) which was divided in to four groups, the first non confined, being the reference group, the remaining groups consisted of two specimens each with only one variable being the degree of strengthening that is the numbers of confinement layers. The second, third, and fourth group were confined with one, tow, and three layers respectively. All specimens were tested through the application of a vertical load up to failure. The result indicated that there is a clear indication of shear strength increase amounting to 33% relative to the reference specimens (non confined), also there was a noticeable increase in the absorption capacity as a function of the number of confinement layers.
