Research Themes
Design for Natural Hazards
We aim to reduce the impacts of natural hazards like earthquakes using large-scale tests and field data to better understand behavior and improve design.
Assessment and Repair
As U.S. infrastructure ages, there is a pressing need to more efficiently assess existing structures and devise improved retrofit methods.
New and Advanced Materials
We study advanced materials like high-strength steel and ultra-high-performance concrete to improve the behavior and constructability of structures.
High temperature effects
We study the mechanics of reinforced concrete at high temperature to support the development of advanced nuclear reactors.
Current Research Projects
Deformation Capacity of Column-Foundation Connections
Buildings must be able to deform without losing strength during earthquakes. We are working to understand the mechanics of column-foundation connections to improve design requirements.
Assessment and Repair of Concrete Dams
Thousands of concrete dams in the U.S. are aging. Our team is developing methods to better assess whether structures can continue to serve safely and improved methods to repair and extend the service-life of structures.
Earthquake-Resistant Walls with Mechanical Splices
Nuclear power plants and tall buildings rely on reinforced concrete walls when earthquakes occur. We are studying special reinforcement details and advanced materials to improve behavior and reduce the cost of safe buildings.
Bridge Load Rating and Repair
Our team devises new, more cost-effective, methods for determining the safe load capacity of existing concrete bridges. We are also developing models to more accurately assess the effects of repair choices like replacing bridge decks on long-term performance.
Concrete Mechanics at High Temperature
Our group is studying concrete the mechanics of how concrete and steel reinforcement interact at high temperature. This work is important for the development of advanced nuclear reactors.
