Investigation of the Suitability of the Bazant Endochronic Material Model for Modelling the Concrete in a SAMSON Analysis of a Reinforced Concrete Beam.
Abstract
This investigation involved evaluating the potential of the Bazant endochronic (plain concrete model as a possible avenue to an accurate model of the behavior of dynamically loaded reinforced concrete structures. A previous attempt to apply this model to the problem of a dynamically loaded beam was unsuccessful, due to an instability in the computer formulation of the model. In this study it was found that interaction between the tensile cracking model and the SAMSON nonlinear dynamic finite element structural analysis program used for the beam analysis problem resulted in inconsistent definition of the strain behavior experienced by the material, thereby producing instability. A procedure was developed and demonstrated, which successfully eliminated the instability. (Author)
