Research and Background

Dr. Breña's research interests include design and behavior of reinforced and pre-stressed concrete structures and bridges, use of fiber-reinforced materials in civil infrastructure applications (bridges), and field performance of bridges. Recent research projects include investigations on the use of fiber-reinforced composites to strengthen existing reinforced concrete bridge beams and columns, design and behavior of structural concrete elements using strut-and-tie models, field performance of integral abutment bridges, and live-load testing of existing bridges. He has also worked on developing and testing concrete mixtures with high early strength properties for accelerated bridge construction.
