Selected publications
These publications represent my main research line on structural robustness, progressive collapse, steel and composite frames, and experimental–numerical validation under extreme actions.
Experimental testing and numerical modelling of steel moment-frame connections under column loss
Engineering Structures, 2017
Combines experimental testing and calibrated numerical models to study how steel connections behave in column-loss scenarios.
Experimental testing and numerical analysis of 3D steel frame system under column loss
Engineering Structures, 2016
Studies the system-level response of a 3D steel frame after column loss, showing how load redistribution and structural continuity contribute to progressive-collapse resistance.
Improving the structural robustness of multi-story steel-frame buildings
Structure and Infrastructure Engineering, 2015
Examines design strategies for improving the robustness of multi-storey steel-frame buildings, with focus on alternative load paths, continuity, and progressive-collapse resistance.
Experimental testing and numerical modeling of steel frames under close-in detonations
Procedia Engineering, 2017
Combines blast testing and numerical modelling to evaluate how steel frames respond to close-in detonations and other extreme loading scenarios.
Impact modelling for progressive collapse assessment of selective rack systems
Thin-Walled Structures, 2019
Extends progressive-collapse assessment to selective rack systems, using impact modelling to study local damage, vulnerability, and structural response beyond conventional building frames.

Research Aims
Structural Engineering & Resilience
- Advance the robustness and resilience of building structures, particularly steel and composite frames, under accidental and extreme actions (e.g. blast, column loss, seismic events).
- Support performance-based and risk-informed design, contributing to safer, more adaptive structures and the development of Eurocode methodologies.
Experiment + Simulation Synergy
- Bridge experimental and numerical approaches, by designing and calibrating full-scale structural tests in tandem with advanced finite element modeling.
- Translate test results into real design practices, enabling engineers to use validated, innovative structural solutions.
Interdisciplinary and Societal Engineering
- Make engineering relevant across disciplines by connecting it with urban narratives, civic needs, and cultural contexts.
- Engage students and the public in structural thinking, turning resilience into a shared concept through immersive learning, design storytelling, and participatory tools.
