Welcome to Tatar Research Group at the University of Delaware

Across the country, our transportation infrastructure is aging. Designed to last a certain amount of time, our nation’s bridges are reaching the end of their design life. Approximately 46,000 bridges, are considered to be in "poor" condition, on which we daily take 178 million trips. Today, the estimated cost to rehabilitate our deficient bridges is $125 billion – posing a significant burden on taxpayers. Without remediation, bridges that are rated as "poor" are also in danger of collapsing, which may lead to deaths and damage to surrounding property.

Moreover, population in the coastal regions are feeling the wrath of climate change, which has led to an increase in hurricanes, flooding, and sea level rise. The climate change also causes higher rates of degradation in buildings and transportation infrastructures which makes them highly vulnerable to collapse under natural hazards.

The main goal of our research is to develop and integrate advanced materials in bridges, residential, and commercial buildings, to make them more durable and resilient when faced with today’s natural hazards. The use of appropriate materials to repair existing structures and to construct new structures can reduce maintenance efforts and slow down deterioration, ultimately improving structural performance, and reducing overall lifecycle costs.

Two wins!

March 8, 2021

Tatar Research Group has been awarded two new projects, by NSF and CIAMTIS.

Prof. Tatar is leading the NSF REU Site in Sustainable Resilient Transportation Systems. We focus on convergent research aimed at eliminating transportation-related carbon emissions to combat climate change. The first cohort of students will join us at UD in Summer 2022. Stay tuned for application info and additional details.

We also received a new collaborative project from CIAMTIS focused on "Mitigating Cracking in Ultra-High Performance Concrete (UHPC) Bridge Connections”! We are excited to contribute to improved UHPC connections in bridges. Our collaborator on the project is Prof. Farshad Rajabipour at Penn State.
