title = "Finite element analysis of the seismic response of rc columns with modified bond properties",
abstract = "This paper presents results of a numerical investigation on the seismic performance of RC columns with modified bond properties. Three-dimensional nonlinear finite element models of columns tested under cyclic lateral loading have been developed. The finite element models comprise a triaxial constitutive model for concrete that is capable of simulating compression failure and tension cracking under cyclic loading. The bond-slip behavior of longitudinal reinforcing bars has been modeled using a concrete-steel interface element. The interface element has a bond stressslip constitutive law that predicts bond deterioration caused by bar slip, cyclic loading and tensile yielding of steel. The finite element models predict well the force-displacement response and strain distributions along the longitudinal reinforcement of the columns subjected to cyclic loading. The experimentally-verified models have shown that partial debonding of longitudinal bars can effectively reduce the maximum and cumulative strains experienced by the bars in the plastic hinge region of the columns.",
