Simulation of a Cyclic Loading Test of Reinforced Concrete Column with Plastic Damage

Simulation of a Cyclic Loading Test of Reinforced Concrete Column with Plastic Damage

Reinforced Concrete (RC) is one of the most common engineering materials. However, the complex mechanical properties of this material are not easily predicted when the continuity between the reinforced steel bars and concrete is broken due to microcracks in the plastic deformation region. Therefore, the continuity-based theory is applicable only in a limited range of failure. Finite Element Analysis (FEA) with Concrete Damaged Plastic (CDP) model was applied to simulate cyclic loading tests of RC column in this paper. It has been shown that the FEA with CDP model can predict the failure region of concrete and its hysteresis loop of lateral force-displacement when the drift ratio is smaller than 2%, which can be used to study more detailed plastic behaviors of RC components.
