    Microplane Model Parameters Estimation Using Soft Computing Methods

  • Original language description

    Concrete as a man-made heterogeneous material shows very complex nonlinear behavior which is extremely difficult to model both theoretically and numerically. The microplane model is a fully three-dimensional material law that includes tensional and compressive softening, damage of the material, different combinations of loading, unloading and cyclic loading along with the development of damage-induced anisotropy of the material. As a result, it is fully capable of predicting behavior of real-world concrete structures once provided with proper input data. Although the authors of the model proposed a heuristic calibration procedure, it is based on the trial-and-error method and provides guide to determination of selected material parameters. Therefore, areliable and inexpensive procedure for parameters identification of this model is on demand. In the view of potential improvements proposed in a recent work on soft computing methods, a new procedure based on artificial neural networks .
