The paper shows main results of cyclic compression tests performed on R.C. columns confined by FRP jackets. The specimens are 250x250 mm square section columns, reinforced and unreinforced by steel bars and stirrups. Experimental results are compared with the analytical model performed by Braga-Laterza-Gigliotti (1998, 1999, 2001) that takes into account, at the same time, the confinement of FRP jackets and of the internal steel stirrups. The comparisons highlighted the good capability of the analytical model to evaluate the confined behaviour of the tested columns.

Abstract
The paper shows main results of cyclic compression tests performed on R.C. columns confined by FRP jackets. The specimens are 250x250 mm square section columns, reinforced and unreinforced by steel bars and stirrups. Experimental results are compared with the analytical model performed by Braga-Laterza-Gigliotti (1998, 1999, 2001) that takes into account, at the same time, the confinement of FRP jackets and of the internal steel stirrups. The comparisons highlighted the good capability of the analytical model to evaluate the confined behaviour of the tested columns.File in questo prodotto:
