From Safety to Resilience: A Comprehensive Perspective on the Seismic Performance of Buildings

When: 19 May 2026, 15:30 - 16:30 hrs CET 

Register (Free) online: Click here for registration and further information. 

This webinar is being organised by an external source, organised by the Spanish NG, and language will be Spanish.

Speaker: Marco F. Gallegos Calderon. Moderator: Dolores Pulido.

This presentation addresses the seismic performance of reinforced concrete buildings from a modern resilience-oriented perspective, moving beyond the traditional life-safety focused approach. Within the framework of performance based earthquake engineering, it will be shown how key aspects such as economic losses, functional continuity, and recovery times can be incorporated from early design stages, enabling a more comprehensive understanding of building performance under seismic events. From the Chilean experience, characterized by recurrent large-magnitude earthquakes and stringent, advanced seismic design codes, a methodological approach based on FEMA P-58, adapted to local contexts, will be discussed. This approach incorporates not only technical variables but also realistic occupancy conditions. The presentation will emphasize how these tools can support decision-making in the design and assessment of assets, creating opportunities to optimize costs, enhance resilience, and reduce lifecycle risk in the built environment. Finally, the applicability of these approaches to other contexts, such as Europe, will be explored, highlighting opportunities for collaboration toward more resilient, sustainable infrastructure aligned with current industry demands.

Speaker: Marco F. Gallegos Calderon is a Civil Engineer and faculty member at the Faculty of Engineering at the Universidad del Bio-Bio (Chile), where he conducts teaching and research in earthquake engineering. His work focuses on the performance and risk assessment of structural systems, with an emphasis on performance-based and resilience-oriented approaches. He has participated in international projects and collaborations across the Americas and Europe aimed at advancing safer and more sustainable infrastructure. His research integrates probabilistic methods with emerging technologies such as artificial intelligence and virtual/augmented reality, applying them to real-world engineering problems. This approach has enabled him to effectively bridge research and teaching, contributing to the education of future engineers and the development of innovative solutions for the industry.

After registering, you will receive a confirmation email containing information about joining the webinar.

Speaker: Heqiang Tang, Professor Level Senior Engineer, Project Design Manager of the Nanjing Xianxin Road Yangtze River Crossing, China

Moderator: Limin Sun, Vice President of IABSE, President of Chinese NG, Prof. Dr. Civil Eng., P.E., Tongji University, China

The Nanjing Xianxin Road Yangtze River Crossing, located in China’s busiest inland river port area, has a total length of 13.17 km. The project comprises the main bridge, approach bridges, tunnels, interchanges, roadbeds and other structures.

The design and construction face exceptional challenges, including wind resistance and fire protection for the super-long-span suspension bridge, structural durability, cost control, and the protection of ecological parks, railways, cultural relics and Yangtze River embankments.

To address these challenges, the team implemented a series of technical innovations, including low-damping wind-resistant technology, integrated fire and corrosion protection technology, innovative foundation design methods, advanced material development, and carbon emission reduction technologies. After five years of construction, the project was opened to traffic and has become a new landmark in the region.

Circular Construction in Steel Structures: The Key Role of Connections

When: 27 November 2026, 14:00 - 15:30 hrs CET 

Register (Free) online: Click here for registration and further information.

                                                       After registering, you will receive a confirmation email containing information about joining the webinar.

Speakers: Luis Simoes da Silva;  Filip Ljubinković; Kristo Mela; Tiago Alves; Alejandro Bernabeu. Moderator: Dolores Pulido.

Steel structures offer a unique advantage for circular construction due to their durability, adaptability, and high potential for reuse and recyclability. However, the practical implementation of reuse strategies presents several challenges, including limited availability of reusable elements, the carbon footprint associated with deconstruction processes, the lack of standardized design rules for reuse, and broader economic and industrial constraints.

Connections play a fundamental role in enabling circularity in steel structures. They are key to facilitating disassembly, adaptability, and reuse, while also representing a significant share of the overall structural cost and complexity.

Building on the experience gained within the European Union-funded CONNECT4C project, this webinar will explore the context and potential of circular construction in steel structures. It will address the key requirements that such systems must satisfy, the challenges associated with their development at the system, component, and connection levels, and present the CONNECT4C project, focused on the development of high-strength, demountable, reusable, and adaptable steel connections.

Speakers: Luis Simoes da Silva, Portugal, University of Coimbra; Filip Ljubinković, University of Coimbra; Kristo Mela, Tampere University, Finland; Tiago Alves, Adao da Fonseca Engenheiros Consultores, Portugal; Alejandro Bernabeu, Bernabeu Ingenieros, Polytechnic University of Madrid, Spain. 

Moderator: Dolores Pulido, Spanish National Group Chair.
