SUMMARY:Projection-Based Model Order Reduction and Hyper-Reduction for Non-Linear Electromagnetic Problems
DESCRIPTION:On Wednesday\, July 1\, a seminar titled “Projection-Based Model Order Reduction and Hyper-Reduction for Non-Linear Electromagnetic Problems” will be held in Grandori Room (Building 4) at 14:00 CET.\nThe seminar will be given by Prof. Daniel Rixen\, Technical University of Munich. \nAbstract\nOver the last decade\, several new techniques to efficiently reduce non-linear structural problems for transient analysis have been proposed. This seminar will outline the main concepts of projection-based approaches\, in particular how meaningful projection spaces can be constructed and how the computational cost of computing the non-linear forces can be mitigated (hyper-reduction). The ideas will then be extended to electromagnetic problems and to the computation of the associated magnetic forces on structures.

SUMMARY:Surrogate modelling for hydromorphodynamic across scales
DESCRIPTION:On Thursday\, July 9\, as part of a session of two consecutive seminars starting at 10:00 CET\, a seminar titled “Surrogate modelling for hydromorphodynamic across scales” will be held in Grandori Room (Building 4).\nThe seminar will be given by Yifan Yang\, Professor of River Engineering at Wuhan University. \nAbstract\nThis seminar presents two complementary surrogate-modelling strategies that learn compact mappings between observable or simulated flow states and otherwise inaccessible or future hydromorphodynamic responses.\nAt the local scale\, an encoder–decoder network learns the relationship between instantaneous surface-flow fields and mean near-bed hydrodynamics\, thereby providing a pathway to infer scour-relevant processes from image-based or remotely sensed observations. Gradient-SHAP analysis identifies localised regions that contain the dominant hydrodynamic signatures\, while a multiresolution strategy combines high-resolution in situ monitoring of critical zones with coarser\, wider-area drone observations. The compressed regions of interest retain sufficient information to reconstruct near-bed fields while substantially reducing data and computational requirements\, supporting the identification of scour progression\, bed mobility and instability.\nAt the river-reach scale\, an Adaptive-Horizon Graph Neural Operator learns bed updating directly on native unstructured meshes while retaining hydrodynamic feedback from a 2D hydrodynamic solver. It maps recent hydrodynamic and topographic states to future bed-elevation increments\, with the effective history length and update interval adapting to the evolving flow–bed system. Trained using validated morphodynamic solutions and evaluated on several benchmarks\, the model reproduces dominant bedform migration\, erosion and deposition patterns while achieving approximately 100x accelerations.\nTogether\, these studies demonstrate a cross-scale pathway from measurement-informed inference to accelerated morphodynamic forecasting\, offering a foundation for rapid scenario analysis\, smart scour monitoring\, early warning\, and hydromorphodynamic digital twins.\n\nBio-sketch\nYifan Yang is Professor of River Engineering at Wuhan University and a recipient of the National Science Fund for Excellent Young Scientists (Overseas). He received his PhD in Civil Engineering from the University of Auckland and previously worked as a lecturer at the University of Waikato\, a postdoctoral researcher at the University of Auckland\, and a civil engineer at Wellington Water. His research focuses on scour and erosion hazards around river and coastal infrastructure\, data-driven hydro-morphodynamics and sediment transport\, and AI-enabled flood risk management and digital twins. He has developed experimental\, numerical and machine-learning approaches for bridge scour prediction\, turbulent flow-field reconstruction\, streambed morphology analysis\, and infrastructure resilience assessment.

SUMMARY:Sustainable Concrete Infrastructure
DESCRIPTION:On Friday\, July 10\, a seminar will be held in Room 087 (first floor\, Building 4)\, starting at 12:30 CET. \nThe seminar will be given by Rebecca Gravina\, Professor and TMR Chair of Structural Engineering in the School of Civil Engineering at The University of Queensland (Brisbane\, Australia)\, and is titled “Sustainable Concrete Infrastructure”. \nAbstract\nSustainable concrete infrastructure responds to the growing challenges posed by ageing\, carbon-intensive assets and increasing exposure to climate extremes and natural hazards. Existing concrete infrastructure is often deteriorating due to reinforcement corrosion\, cracking\, creep\, and overloading\, resulting in high maintenance costs and reduced service life. In this context\, durability\, not strength alone\, becomes the governing factor for sustainability. Conventional concrete also presents significant environmental concerns\, including high CO₂ emissions during production and extensive resource depletion from natural aggregate extraction. With concrete being one of the most widely consumed materials globally\, these issues highlight the urgent need for innovative\, system-level solutions that improve performance while reducing environmental impact and supporting long-term resilience. \nTo address these challenges\, Professor Gravina will present her research\, with emphasis on low-carbon concrete strategies aimed at reducing embodied carbon while maintaining structural performance. Approaches include the use of supplementary cementitious materials\, recycled aggregates such as recycled concrete\, crushed glass\, and industrial by-products\, and optimised mix designs that balance cost\, carbon\, and performance. Experimental results demonstrate that sustainable concrete can achieve comparable workability\, strength\, and durability while significantly reducing reliance on natural resources and landfill demand. Life cycle assessment outcomes further indicate substantial reductions in greenhouse gas emissions and waste diversion potential. In parallel\, advanced material systems such as fibre-reinforced polymer reinforcement and ultra-high-performance concrete enable enhanced durability\, corrosion resistance\, and service-life extension. These innovations support prefabrication\, rapid construction\, and reduced maintenance\, contributing to resilient\, low-carbon infrastructure aligned with circular economy and decarbonisation objectives. \nSpeaker’s bio\nRebecca Gravina is Professor and the TMR Chair of Structural Engineering in the School of Civil Engineering at the University of Queensland in Brisbane\, Australia. The TMR Chair position is endowed by the Queensland Government Department of Transport and Main Roads (TMR). She obtained her PhD in Structural Engineering from the University of Adelaide and\, prior to joining academia\, worked as a consulting Structural Engineer with ARUP. Professor Gravina is an established researcher with over 25 years of experience in academia and consulting engineering. Her research field concerns the long-term performance and durability of reinforced concrete (RC) and prestressed concrete (PC) structures\, sustainability of infrastructure\, rehabilitation of existing structures with Fibre Reinforced Polymers (FRP)\, multi-functional self-healing cementitious composites\, recycled materials in concrete\, and engineering education.

SUMMARY:Wind Turbine Blade Flow-Induced Instabilities under Stochastic Load Perturbations and Partially Correlated Turbulence
DESCRIPTION:On Friday\, July 17\, a seminar will be held in Grandori Room\, starting at 15:00 CET.\n\nThe seminar will be given by Luca Caracoglia\, Full Professor in the Department of Civil and Environmental Engineering at Northeastern University (Boston\, USA)\, and is titled “Wind Turbine Blade Flow-Induced Instabilities under Stochastic Load Perturbations and Partially Correlated Turbulence”.\n\nAbstract\nOffshore wind turbine manufacturers are proposing the design of tall\, low-mass towers and long\, flexible blades (up to 100 m and beyond) to increase wind energy extraction and reduce maintenance costs. Long\, flexible blades are sensitive to wind load effects\, either during operational conditions or extreme events. The interaction between the rotating blade and the flow can lead to dynamic vibrations\, aeroelastic interactions and flow-induced instabilities.\nThis presentation will present recent studies on flow-induced instabilities of the blades. Specifically\, the presentation will focus on coupled-mode flutter\, which involves the interaction between flap-wise and torsional vibrations of the blade. Blade flutter may lead to malfunctions\, damage and\, ultimately\, failure of the blades. Investigations will analyze various perturbation sources\, e.g.\, wind turbulence\, loading errors and blade’s structural modeling simplifications. This issue will also analyze the influence of partially correlated turbulence on the loads and the instability. Both stochastic differential equations and Monte Carlo methods will be considered. Verification by wind tunnel experiments will be presented. Although blade flutter is not important for shorter blades\, it will be shown that flutter probability cannot be ignored in the case of long blades\, typical of offshore wind turbines. The presentation will consider the behavior of the NREL (National Renewable Energy Laboratory) 5MW standard offshore wind turbine blade under various wind load scenarios.\n\nSpeaker’s bio\nLuca Caracoglia is a Full Professor in the Department of Civil and Environmental Engineering of Northeastern University\, Boston\, Massachusetts\, USA. Luca Caracoglia’s research and professional interests are in structural dynamics\, random vibrations\, fluid-structure interaction of civil engineering structures\, nonlinear cable network dynamics\, wind engineering\, wind energy and wind-based energy harvesting systems.

SUMMARY:Assessing the Influence of Supplementary Cementitious Materials on the Temperature Dependence of Structural Build-Up of 3D-printable Cementitious Pastes
DESCRIPTION:On Tuesday\, July 21\, a seminar will be held in Grandori Room\, starting at 12:00 CET.\nThe seminar will be given by Ivan Navarrete\, Assistant Professor in the Department of Construction Engineering and Management at the School of Engineering of Pontificia Universidad Católica de Chile and Director of the UC Concrete Innovation Hub\, and is titled “Assessing the Influence of Supplementary Cementitious Materials on the Temperature Dependence of Structural Build-Up of 3D-printable Cementitious Pastes”.\n\nAbstract\nThe early-age structural build-up of cementitious materials is strongly influenced by temperature\, yet the role played by the intrinsic properties of supplementary cementitious materials (SCMs) on the thermal dependency of this process remains insufficiently understood. This study investigates the effect of the particle size and physicochemical properties of SCMs on the temperature-dependent evolution of the storage modulus (G′) of cementitious pastes. A comprehensive experimental program was conducted using a range of SCMs characterized by distinct particle size distributions\, and surface electrochemical properties. Oscillatory rheological measurements were performed under controlled temperature conditions to monitor the evolution of the storage modulus during the early stages of hydration. In addition\, the interaction between SCM properties and key mixture design parameters—namely the water-to-cement ratio and the cement replacement fraction—was systematically evaluated. The results reveal that both the physical characteristics and electrochemical surface properties of SCMs significantly influence the rate and magnitude of structural build-up\, as well as its sensitivity to temperature variations. Furthermore\, these effects are strongly modulated by mixture design parameters\, highlighting the coupled role of SCM characteristics and mixture composition in governing early-age rheological behavior. The findings provide new insights into the mechanisms controlling structural evolution in blended cement systems and contribute to improving mixture design strategies for applications sensitive to early-age rheology\, such as digital fabrication and 3D concrete printing.\n\nSpeaker’s bio\nIvan Navarrete is an Assistant Professor in the Department of Construction Engineering and Management at the School of Engineering of Pontificia Universidad Católica de Chile\, where he also serves as Director of the UC Concrete Innovation Hub.
