Welcome
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 the seismic design and evaluation of steel structures. We currently investigate the collapse capacity of conventional and high performance steel structures subjected to extreme earthquake loading. Recent work focuses on the utilization of innovative steel materials for multi-hazard mitigation, 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 steel buildings. Of particular interest is the experimental evaluation of steel beam-columns, the evaluation of cumulative damage effects on steel beam-to-column connections and the development of high-fidelity computational models for performance-based evaluation of conventional and high performance steel structures.
