Abstract

Abstract

Research on concrete constitutive model actually studies constitutive relation of concrete. Cumulative deformation of material can cause interior damage of structure under exterior load and the entire structure may collapse due to damage of concrete. According to energy dissipation damage theory by Najar, a new model of segments curves damage of concrete compression is investigated and equations are put forward for damage variables and evolvement with various degrees of concrete. In order to testify the validity of the model, the calculated results are compared with those of the existing constitutive model, and the result shows that the proposed model is agreed with the existing model, which may provide a new method for simulation analysis of damages to concrete structures.
- concrete,
- damage of uniaxial compression,
- energy dissipation,
- equation of damage evolvement
