Abstract:
Introduces a new material model for concrete. It allows a realistic description of the complex behavior of concrete loaded by monotonic and cyclic tension. The model consists of rheological elements. The envelope and the hysteresis loops for all kinds of cyclic loading are described by the same model. The numeric of the model is very simple and easy to use in connection with finite element codes. The model is proven by recalculations of test results of different test setups.
