Welcome to the web site for Dimitrios Lignos’ research group. Our work focuses on the development of performance-based assessment techniques and use of integrated experimental and analytical methods for seismic design and evaluation of structural systems. We currently investigate the collapse margins of conventional and high performance structural systems subjected to extreme earthquake loading. Recent work focuses on the development of rapid earthquake damage assessment techniques of infrastructure facilities, and the effect of welding procedures on heavy build-up members and high strength steel for the seismic and blast design of tall buildings. Of particular interest is the seismic design and evaluation of steel beam-columns, the evaluation of cumulative damage effects on steel beam-to-column connections and the development of simulation models for performance-based evaluation of conventional and high performance steel frame structures.
