Calibration of a New Concrete Damage Plasticity Theoretical Model Based on Experimental Parameters

The introduction of concrete damage plasticity material models has significantly improved the accuracy with which structural elements can be predicted in terms their response. Research into this method's analyzing complex forms been limited. A model combined a model, based on continuum mechanics, is recommended for effectively predicting and simulating behaviour. parameters, such as compressive tensile damages, defined to simulate behavior damaged-plasticity accurately. This research aims propose an analytical assessing stiffness deterioration. proposed method determine variables at start loading process, variable continues increase load progresses until complete failure. results obtained using were assessed through previous studies, whereas three case studies specimens reinforced (columns gable beams) considered. Additionally, finite element also developed verified. revealed good agreement each case. Furthermore, show that outperforms other methods prediction, particularly when calculated stress ratio.
