Topic: Conceptual Design - Conceptual Design is the stage of the projects when engineers have to be creative to propose the best solutions.
Speaker: Prof. Hugo Corres Peiretti, Prof PhD MSc BSc(Eng) FIStructE fib Honorary President Ffib, FHECOR.
Moderators: Prof. Alfred Strauss (Chair, Austrian NG); Eftychia Apostolidi (e-Learning Board, Germany).
Date and Time: (Postponed, date to be announced).

Summary: Engineers are not aware that we are creating every day, every time we face a project. We have to use this creativity not only to build more beautiful structures, but to mainly build structures - that are capable of responding to all the demands imposed on each project in a holistic way, like structural efficiency, constructive suitability, sustainability, etc. It is an activity that one learns over time, with experience. This webinar shall describe the Conceptual Design process with different case studies.
Hugo Corres Peiretti is a Civil Engineer, MSc and PhD from the Technical University of Madrid. Doctor Honoris Causa from the Technical University of Bratislava. Professor of Structural Concrete and Conceptual Design of Structures at the School of Civil Engineering at the Technical University of Madrid. fib Fellow. FIStructE. Honorary President of fib (International Federation of concrete). Former president of ACHE (Structural Concrete Scientific Association of Spain). Member of the Project Team that prepared Eurocode 2 (Structural Concrete). Founder and designer of FHECOR Consulting Engineers.

Summary: Bridges and transportation infrastructures have a huge social and economic impact on our lives which has often led to adopting a cost-efficient perspective in their design. However, cost-effective structures often tend to minimize labor costs and utilize more materials with more embodied energy. The construction industry is today one of the largest contributors to carbon emissions in the world while emission reduction is necessary to contribute to the climate goals. Less and better's key focus is to fully recognize our planet's limited resources and maximize the design quality under these specific circumstances: to do more with less. Less and better is about appreciating the many dimensions and complexities of the project, including the technical aspects, historical and social context relations, visual qualities, and environmental and economic development constraints. The "less and better" design approach is aligned with the ethical engineer's duty to observe the collective welfare as paramount: to build better bridges sympathetic to the intellect's pleasures and sustainability principles. This webinar will focus on good design practices to achieve sustainable bridges by efficiently using advanced materials, or by building with nature-based renewable, bio-degradable, or low embodied energy materials. Several examples of sustainable bridges built using duplex stainless steel and GFRP will be presented together with bridges designed in bio-composite material in the framework of the ‘Smart circular bridge’ EU project.
Juan A. Sobrino is the founder and president of Pedelta. He has performed the conceptual and detailed design of a wide variety of medium to long-span bridges, including cable-supported structures, arches and segmental bridges. Juan’s noted accomplishments include innovative bridges in duplex stainless steel and GFRP. Numerous of his designs have received prestigious awards for their elegance and innovative values.
Stephanie Lamerichs is the project manager for the Interreg NWE research project Smart Circular Bridge with lead partner Eindhoven University of technology. With a background in structural engineering and a passion for sustainability she wants to improve the design and materialization of bridge structures. Therefore she also leads a circular infrastructure team within engineering company Witteveen+Bos.
Topic: Post-Flutter Behavior of Long-Span Bridges Under Climate Change
Speaker: Dr. Teng Wu
Moderator: Dr. Andre Orcesi (TG 6.1 Chair)

Summary: The intensified storms in our changing climate post a flutter risk to coastal long-span bridges. This talk first presents a Climate-dependent Stochastic Simulation Framework for Tropical Cyclones (TCs) developed at University at Buffalo. The post-flutter behaviour of long-span bridges under the obtained TC boundary-layer winds is then simulated by coupling a knowledge-enhanced LSTM network with the 3D finite-element model. A promising experimental approach based on the real-time aerodynamics hybrid simulations is also introduced for wind-tunnel validations of the nonlinear post-flutter modeling. Finally, an interactive aerodynamic design concept based on a knowledge-enhanced convolutional neural network is discussed to facilitate the search for optimal deck shape in bridge wind retrofitting design.
Speaker: Dr. Teng Wu is an Associate Professor in the Department of Civil, Structural and Environmental Engineering at the University at Buffalo (UB). Wu has made significant contributions to the development of analytical and computational methods focusing on nonlinear and transient structural aerodynamics, performance-based wind design, and community resilience to hurricane (wind, rain and surge hazards). Wu currently serves as the Chair of ASCE Technical Committee on Future Weather and Climate Extremes.
Moderator: Dr. André Orcesi is deputy director of the technical department of bridges engineering in Cerema (Centre for Studies on Risks, Environment, Mobility and Urban Planning) in France. He is an expert in reliability of infrastructures, structural health monitoring, management, maintenance, optimization, and life-cycle costs. He is a member of several international scientific committees and chair of IABSE TG 6.1: Effects of Climate Change on Infrastructures.
