Damage Model Based Reinforced-Concrete Element
Publication: Journal of Materials in Civil Engineering
Volume 15, Issue 4
Abstract
In this paper, the damage in concrete around a reinforcement bar is examined, and three types of damage in concrete and at the concrete-rebar interface are defined. Based on these definitions, a three-dimensional damaged reinforced-concrete (DRC) element is proposed. The element consists of a 10-node concrete element, a two-node rebar element, and a four-node concrete-rebar interface element. Experiments were carried out to obtain the parameters for the bond damage evolution equation. The proposed DRC element is implemented as a user-defined element of MSC MARC2000, a commercial finite-element analysis software package. Two numerical examples were examined, and the results show that the DRC element can simulate the bond deterioration in reinforced-concrete structural members with sufficient rationality, accuracy, and efficiency.
