Inclusion of Smeared Cyclic Bond-Slip Behavior in Two-Dimensional Membrane Elements

This paper describes the development of a rational, but highly simplified, smeared bond-slip model that offers an improvement over existing two-dimensional (2D) total-strain based reinforced concrete membrane models, The new model divides a 2D element into bonded and slip regions in the direction perpendicular to the tensile crack orientation. It is essentially a friction model that evaluates maximum frictional stress in a frictional block between the concrete and steel reinforcement. Cyclic panel test results from the literature are used to validate the proposed model. The proposed model is capable of modeling tension stiffening and crack closing behaviors as well as concrete and steel reinforcement compatibility, including prediction of the crack strains under cyclic loading.
