Development of Advanced Constitutive Models for Plain and Reinforced Concrete.
Abstract
The basic goal of the research described here is to construct an advanced, nonlinear, multi-axial, non-phenomenological constitutive model of reinforced concrete that will provide simulation accuracy in the nonlinear regime which is superior to existing theories. Particular attention is given to modeling the interaction between plain concrete and rebar, as well as to the development of an accurate theory for plain concrete. Toward these objectives, the following important advancements are described: 1) extension of the endochronic plain concrete model to more accurately describe failure states and to allow treatment of the full nonlinear range of hydrostatic behavior, 2) development of a new continuous damage theory for plain concrete, 3) extension of the basic reinforced concrete mixture model to include additional steel-concrete interaction mechanisms, and 4) validation of new mixture theory through comparison between simulation and experimental data for the tension stiffening and dowel action problems.
