The behavior of r.c. columns wrapped by composite material sheets (FRP) under axial force and cyclic bending is studied. Cyclic constitutive laws for confined and unconfined concrete in compression, for concrete under tension and for steel reinforcing bars are introduced. Numerical results are in good agreement with experimental tests. Hysteretic dissipated energy for cyclic bending is also estimated. Wrapping with FRP is shown to be very effective, increasing significantly ductility of columns under bending.

Abstract
The behavior of r.c. columns wrapped by composite material sheets (FRP) under axial force and cyclic bending is studied. Cyclic constitutive laws for confined and unconfined concrete in compression, for concrete under tension and for steel reinforcing bars are introduced. Numerical results are in good agreement with experimental tests. Hysteretic dissipated energy for cyclic bending is also estimated. Wrapping with FRP is shown to be very effective, increasing significantly ductility of columns under bending.File in questo prodotto:
