In collaboration between UCL (The Bartlett), the International Hellenic University, and Pontificia Universidad Católica de Chile, this work introduces a new methodology for assessing bridge portfolios under seismic hazard.

Key contribution

While seismic intensity is commonly used as the dominant parameter for structural demand, this paper demonstrates that earthquakes with the same intensity level can lead to dramatically different structural responses. This is due to variations in:

• Frequency content
• Duration
• Spectral characteristics of ground motion

This record-to-record variability represents a major source of aleatory uncertainty in seismic assessment.

What the methodology offers

The article proposes an integrated workflow that:

• Explicitly quantifies record-to-record variability
• Uses nonlinear time-history analysis for realistic structural response
• Employs statistical modelling and closed-form predictive expressions
• Generates interpretable predictive models for μ\muμ and σ\sigmaσ of seismic demand parameters (EDPs)

This enables fast and traceable assessment of large-scale bridge networks, moving beyond structure-by-structure evaluation.

We are pleased to announce the publication of our latest scientific contribution in Energy & Buildings (Elsevier).

This review article introduces a systematic and integrated framework for passive ventilation in thermally modernized and nearly zero-energy residential buildings, combining:

• Climate-responsive building aerodynamics
• Hybrid passive ventilation strategies
• Digital design and evaluation using CFD, Building Energy Simulation (BES), and experimental validation

The paper demonstrates how passive and hybrid ventilation can achieve meaningful energy savings while maintaining indoor environmental quality — bridging the gap between traditional passive design and advanced digital modelling.

This research advances the development of next-generation, low-carbon ventilation solutions and supports the transition toward sustainable and climate-resilient housing.

MetaInfrastructure (in partnership with The Bartlett, UCL) is pleased to announce the publication of a new paper in Nature Communications: “Rethinking infrastructure design from component failure to systemic resilience.”

The study asks: Should all critical infrastructure be built equally? It argues that we must design and value infrastructure based on its systemic impact, geo-economic role, and recovery potential across interdependent systems.
Using the Francis Scott Key Bridge collapse (Baltimore) as a case study and the “TranSight” regional economic model, the paper shows that combined bridge-and-port failures generate substantially larger losses in GDP, employment and income, with some indicators not recovering until 2040.
The work marks a major shift from traditional load-based design standards to a resilience-based framework for critical interconnected infrastructure.

Shanghai, China — September 2025

Professor Stergios-Aristoteles Mitoulis, Professor at University College London (UCL), The Bartlett School of Sustainable Construction, concluded his academic visit to Tongji University with a workshop on Building Systemic Resilience.

The workshop addressed critical aspects of resilience planning, including:

• Systemic and asset-specific resilience
• Costs of asset renovation and import dependencies
• Resource availability and compounding impacts

These discussions highlighted the importance of integrating economic and material considerations into resilience frameworks.

Professor Mitoulis expressed his appreciation to Professor Dongmei Zhang (Dean) and Professor Xiaowei Wang for their warm welcome and engaging discussions.

This workshop marked the conclusion of his activities in Shanghai before travelling to Torino, Italy, for the upcoming ARTISTE Conference on Infrastructure Resilience.

A new review article co-authored by Professor Stergios-Aristoteles Mitoulis (University College London, Bartlett School of Sustainable Construction), Francesco Pentassuglia, and Dr.Ivan Izonin, has been published in Results in Engineering (Elsevier).

The article, titled “Bridge damage characterisation using machine learning: methods and advances”, presents a state-of-the-art overview of global bridge damage detection and highlights how machine learning (ML) can transform structural health monitoring through deck deflection analysis.

Key highlights include:

• A comprehensive review of bridge damage characterisation methods worldwide.
• A scalable ML approach that reduces modelling effort and improves explainability.
• A physics-based framework linking deflection patterns to actionable damage states.

This collaborative work showcases how AI and engineering can converge to enhance the resilience and reliability of bridge infrastructure.
