To control damage of concrete bridge columns under lateral load particularly due to earthquake loads, the use of energy dissipation devices has been one solution to dissipate energy. These devices coupled with advanced structural materials can offer many advantages as external replaceable fuses. This presentation will examine various types of supplemental energy dissipation devices used for bridge columns along with design methodologies like damage avoidance design (DAD). Results from a few case studies of bridges designed with energy dissipation devices are presented to examine overall column performance.

Speaker:  Monique Head, PhD, Associate Professor at the University of Delaware

Monique.jpgMonique Head, PhD, Associate Professor at the University of Delaware, conducts research to improve bridge performance, especially during earthquakes, using performance-based design methodologies complemented by large-scale structural testing and finite element modeling. The broader impact of her work has included designing a concrete bridge deck system with internally reinforced aramid fiber reinforced polymer (AFRP) bars that met minimum AASHTO loads and deflection criteria. In 2014, she received the American Society of Civil Engineers (ASCE), Maryland Section, Outstanding Educator of the Year Award and the University of Delaware, Department of Civil & Environmental Engineering, Citation for Outstanding Alumni Achievement. Monique Hite Head is a native of Newark, Delaware.  She received her bachelor and master of civil engineering degrees from the University of Delaware in 2000 and 2002, respectively, and PhD in civil (structural) engineering from the Georgia Institute of Technology in May 2007. Prior to joining the faculty at the University of Delaware in August 2018, she was civil engineering faculty at Texas A&M University (2007-2011) and Morgan State University (2011-2018). She is an active member of ASCE, ACI and serves as Secretary for TRB AFF50: Committee on the Seismic Design and Performance of Bridges.
