Homogenised constitutive model coupling damage and debonding for reinforced concrete structures under cyclic solicitations
Abstract
A new stress resultant constitutive model for reinforced concrete plates under cyclic solicitations is
presented. This model is built by the periodic homogenisation approach using the averaging method
and couples damage of concrete and periodic debonding between concrete and steel rebar. In
one-dimensional situations, we derive a closed-form solution of the local problem useful to verify and
set up the plate problem. The one dimensional macroscopic constitutive model involves a limited number
of parameters, the sensibility of which is studied. Comparison to experimental results underlines the pertinence
of the model by considering internal debonding in order to properly represent the mechanical
dissipation occurring during cyclic loadings on reinforced concrete panels.
