My primary research activities have centered on studies of inelastic behavior of reinforced concrete (RC) members and connections under large load reversals (i.e. earthquake-type loading). My more recent research activities have included the use of high-performance fiber reinforced cementitious composites for increased energy dissipation and stiffness retention in critical locations of earthquake resistant RC structures I have also studied the earthquake resistant design of structures of mixed construction, i.e., a combination of steel beams and RC columns. I have significant research and professional experience with seismic repair of damaged RC structures and the seismic retrofit of existing structures to modern seismic design levels. Most of my funding comes from the National Science Foundation and the ACI Concrete Research Council.
