Community resilience is a complex, multi-dimensional problem that relies on the intersection of social science, engineering, economics, and other disciplines to
Today's cement and concrete specifications are based on the 1948 work,” Long-Time Study of Cement Performance in Concrete”. While the 1948 study established
Extreme events test buildings and infrastructure in ways and on a scale that cannot be easily replicated in a laboratory – buildings and infrastructure are
The Earthquake Risk Reduction in Buildings and Infrastructure Program conducts critical research to advance measurement science and enhance performance of the
The onset of structural collapse is used as the acceptance criterion in performance-based seismic engineering, but there is no consensus on how to define
Infrastructure is essential for commerce. Planners and stakeholders want to develop infrastructure that is resilient to both chronic (e.g., material degradation
This project advances key areas of engineering knowledge and practice that are necessary for the development of a robust framework for functional recovery
Improved resilience of the U.S. civil infrastructure requires better knowledge of the performance of concrete structural components. This could be enabled by
