Probabilistic resilience assessment of modular structures

Synopsis

Modular construction is increasingly adopted worldwide due to its sustainability, speed of assembly, and cost efficiency. However, lightweight modular systems exhibit distinct dynamic characteristics that make them sensitive to seismic and wind-induced vibrations. Traditional deterministic design approaches often fail to capture the influence of uncertainties in material properties, connections, and hazard variability. This talk presents a probabilistic multi-hazard framework for assessing the reliability and resilience of modular structures under seismic and wind loading. The methodology integrates uncertainty quantification, surrogate-based modelling, fragility analysis, and resilience metrics to compute failure probabilities and performance degradation under extreme events. The presentation will further introduce adaptive vibration mitigation strategies designed for multi-hazard environments, including innovative concepts that integrate structural control with energy harvesting mechanisms. By linking reliability-based assessment with performance-based engineering, the talk demonstrates how probabilistic approaches can enhance infrastructure safety while supporting sustainable and climate-adaptive design strategies. The session will conclude with perspectives on future directions toward resilience-based structural design and the integration of uncertainty modelling into next-generation engineering practice.

About the speaker

Dr. Said Elias Rahimi is a civil and structural engineer specializing in structural reliability, multi-hazard risk assessment, vibration control, and resilient infrastructure systems. He obtained his PhD in Civil Engineering and is currently a Marie Skłodowska-Curie Postdoctoral Fellow at Leibniz University Hannover. His research focuses on probabilistic performance assessment of modular buildings, uncertainty quantification, adaptive vibration mitigation systems, and resilience enhancement of renewable energy infrastructure such as offshore wind turbines. He has delivered invited lectures at leading international institutions and actively contributes to advancing resilience-based engineering methodologies aligned with European climate adaptation and sustainability objectives.
