CX-270026: Multiple Degradation Mechanisms in Reinforced Concrete Structures, Modeling and Risk Analysis - The University of Houston

The University of Houston proposes to complement ongoing Light Water Reactor Sustainability (LWRS)-funded Grizzly (component aging code) efforts by providing improved multi-physics models that will be incorporated into Grizzly’s framework.  These new developments include 1) coupling between mechanical damage and transport processes, 2) improved representation of the coupling among the transport process, 3) coupling among different scale levels of concrete constituents, 4) probabilistic analysis of the random nature of the heterogeneous concrete structure, environmental factors, and their effects on concrete deterioration, and 5) benchmark verification, validation, and uncertainty quantification of the thermos-hydro-chemo-mechanical concrete formulation.
