Abstract
Purpose To provide a reinforced concrete model including bonding coupled to a classical continuum damage model of concrete, capable of predicting numerically the crack pattern distribution in a RC structure, subjected to traction forces.
Design/methodology/approach A new coupling between bonding model and an alternative model for concrete cracking is proposed and analyzed. For concrete, proposes a damage-like material model capable of combining two types of dissipative mechanisms: diffuse volume dissipation and localized surface dissipation.
Findings One of the most important contributions is the capacity of predicting maximal and minimal spacing of macro-cracks, even if the exact location of cracks remains undetermined. Another contribution is to reiterate on the insufficiency of the local damage model of concrete to handle this class of problems; much in the same manner as for localization problem which accompany strain-softening behavior.
Practical implications Bonding becomes very...
