Welcome to the website of the Resilient Steel Structures Laboratory (RESSLab)
In January 2016 the Laboratory of Resilient Steel Structures (RESSLab) was established under the direction of Prof. Dimitrios Lignos.
The RESSLab integrates the teaching and research related to the design and behavior of steel and composite-steel structures. The central focus of the laboratory is how to develop new approaches, metrics and tools to enhance resilient-based design of steel and composite-steel structures under multiple hazards. This is achieved through integrated experimental and computational research that utilizes the latest advancements in material science with high-fidelity nonlinear finite element analysis validated with multi-scale experimental testing. Our research advances from active collaboration with leading academic institutions and steel industry partners from around the world.
Research topics span across steel buildings and bridges, performance-based earthquake engineering, seismic risk and loss assessment, computational modeling of ultimate limit states such as geometric and material instabilities, multi-scale experimental testing of conventional and high-performance systems.
Please explore our website to learn more about our research and teaching activities. We look forward to collaborate with people in varying areas of expertise with the goal of conducting innovative research on structural steel systems and components to improve the performance quality and safety of civil engineering infrastructure.

New paper in performance-based assessment of steel structures
Congratulations to our team for publishing an ASCE journal paper @ASCEpublishing! With help from SNSF @SNSF_ch, EPFL @EPFL_en and the Applied Technology Council we are working in collaboration with researchers from Stanford University towards nonlinear modeling guidelines for performance-based assessment of new and existing steel structures. The article is featured as the Editor's choice for this month. https://ascelibrary.org/doi/10.1061/%28ASCE%29ST.1943-541X.0002353
Hiroyuki Inamasu presented in SECED2019 conference
PhD student Hiroyuki Inamasu presented during the SECED2019 conference in UK our work on exposed column base connections for enhanced seismic life-cycle of steel structures. A copy of the paper can be found here. Co-authors of the paper were Dr. Albano Sousa and Mr. Gerard Bartirna (Swiss Re, formerly at EPFL, RESSLab).
