Abstract The Flexural behavior of over reinforced sections is faster grown due to the popular retrofit technique among researchers and engineering worldwide. Concretes of higher compressive strength have been produced currently and faster grown due to the designers and contractors. Therefore, the main purpose of this work is to give a better and full understanding of the flexural behavior of over reinforced high strength concrete flexural beams subjected to both static and repeated loading. Experimental tests were carried out on different beams having different grades of concrete and percentages of main steel under static or repeated loads Concrete and steel strains and central deflection at both cracking and ultimate loads were recorded for each tested beam It is shown that the flexural behavior of over reinforced beams under repeated loading is quite different than that under static loading. |
