New Cyclic Tensile Model for Two-Dimensional Finite Element Analysis of RC Members
Abstract eng: This paper presents a new approach for modeling the tensile cyclic response of reinforced concrete (RC) subjected to biaxial stress conditions. The model is based on equilibrium, constitutive and compatibility conditions applied on a cracked RC element with arbitrary reinforcement configuration. Cyclic bond degradation effects are accounted for in order to provide physical meaning to tension-stiffening, crack-closing and crack-opening phenomena. The proposed model was implemented into an orthotropic, smeared-crack membrane finite element based on the fixed-crack assumption. A number of verification examples on reinforced concrete panels, shear critical beams and walls subjected to monotonic and cyclic loading is presented. Emphasis is made on adequate modeling of shear failures, due to its detrimental effect on strength and energy dissipation capacity.
