Research Description

The general research interest of Dr. Rizkalla is in the design, construction and behavior of reinforced concrete and prestressed concrete structures and bridges. During the last thirty years, his research interest has focused on the use of higher performance concrete and fiber reinforced polymer (FRP) materials for the construction, repair and strengthening of structures and bridges. His current research interests include diagnostic and prognostic of structure and bridges using non-destructive monitoring systems.
