Hindi’s area of expertise includes non-linear behavior, modeling, and damage of reinforced and pre-stressed concrete elements under static, cyclic and seismic loadings, confinement of reinforced concrete bridge columns, low-cycle fatigue of bridge elements and reinforcement, behavior of bridges under vehicular live load. His research includes experimental, analytical and finite element modeling of bridges and structures. He has developed a damage model of R/C concrete bridge columns under seismic loading based on degraded energy. Hindi has served as a PI/Co-PI on many research projects sponsored by NSF, Caltrans, IDOT, MODOT, and internally. Hindi has supervised more than 20 graduate students’ research theses.
