NONLOCAL CONTINUUM DAMAGE/PLASTICITY MODEL FOR IMPULSE-LOADED RC BEAMS

The development and implementation of a nonlocal continuum damage/plasticity (CDP) model for the analyses of reinforced-concrete beams are described. Previously proposed formulations were modified and combined into a comprehensive constitutive relationship for the development of this model. It has been verified for various stress paths, and by the analysis of reinforced-concrete beams under impulse loading. The results of the analyses are discussed. It is noted that the combination of the Timoshenko beam element with the nonlocal CDP model and the uniaxial steel model is capable of representing the dynamic behavior of reinforced-concrete beams quite accurately.
