This project investigated the combined effects of environmental aging and earthquakes on concrete bridges. The main focus of the project was to develop novel simulation features for thermo-hygro-chemo-mechanical studies of concrete and integrate them into Grizzly, which is based on the MOOSE finite element framework of the U.S. DOE, to evaluate both mechanical and environmental aging of structural concrete. The goal was to integrate a validated multi-scale and multi-physics approach into Grizzly for risk-informed life cycle analysis of reinforced concrete components in aging nuclear power plants.
