Regular biography
Dimitrios Lignos is a Full Professor at the École Polytechnique Fédérale de Lausanne (EPFL), affiliated with the Civil Engineering Department (CE). His research interests include seismic design and assessment of steel and composite-steel concrete structures, performance-based design, and nonlinear analysis with emphasis on deterioration phenomena. He is also involved in the development of computational mechanics-based simulation and inverse plasticity problems. Prof. Lignos is the Director of the Resilient Steel Structures Laboratory (RESSLAB) and holds a position in the School of Architecture, Civil and Environmental Engineering (ENAC). His work focuses on structural stability, seismic risk assessment, and the integration of experimental and simulation-based methods for structural performance evaluation.
Scholar-generated biography
Dimitrios Lignos is a researcher specializing in Steel & Composite Structures, Earthquake Engineering, Performance-Based Design, and Nonlinear Analysis. His work focuses on the seismic performance of steel moment-resisting frames, collapse prediction under earthquake loading, and the development of structural component databases for performance-based earthquake engineering. He investigates deterioration modeling, sidesway collapse, and the impact of gravity framing on overstrength and collapse capacity. His research also includes computational approaches for collapse assessment, updates to nonlinear modeling parameters, and the evaluation of seismic collapse performance using methodologies like FEMA P695. His studies aim to enhance the seismic resilience of steel structures through advanced analytical and experimental techniques.
