| Abstract: |
Material constitutive laws, defined on the meso-scale, are plugged in a semi-analytical procedure in order to simulate the non-linear global mechanical response under service loading of a reinforced concrete beam strengthened with CFRP. The strain-softening concrete behavior is modeled trough a coupling between elasticity and damage. Keeping track of the damage accumulation enables the accurate evaluation of the level of the stiffness degradation in the structural element throughout the loading history. The remaining load-carrying capacity reserve of the strengthened structure is thus predicted. |
