Evaluation of Nonlinear Constitutive Properties of Concrete

Abstract

This report describes the development of a methodology that allows for the objective evaluation of the predictive capabilities of concrete constitutive models. The structural analysis and design of concrete structures is often based on large-scale finite element computations. A key component of the finite element method is the constitutive model that is usually selected and calibrated based on a few simple tests. The primary reason for this is the lack of understanding of the complex response features of concrete and numerical difficulties encountered when attempting to model these features. Also, the error in response predictions due to an inappropriate constitutive model is difficult to define in a complex large-scale structural analysis problem. (eg)
