IABSE - International Association for Bridge and Structural Engineering

What IABSE - International Association for Bridge and Structural Engineering does

IABSE - International Association for Bridge and Structural Engineering is a non-profit scientific and technical association founded in 1929 and headquartered in Zurich, Switzerland. Its mission is to exchange knowledge and to advance the practice of structural engineering worldwide in service of the profession and society. IABSE serves approximately 3,000 members across more than 100 countries, organized through over 50 national groups, and addresses structural engineering practitioners, academics, students, and corporate members with interests spanning bridges, buildings, and other engineered structures across concept, design, construction, operation, and maintenance phases.

The association's core product portfolio comprises the peer-reviewed Structural Engineering International (SEI) journal, published in partnership with Taylor and Francis; the IABSE Bulletins series covering Structural Engineering Documents (SED monographs, 20+ titles), Case Studies on design, rehabilitation and forensic analysis (including failure investigations such as Chirajara Bridge), and Special Publications on bridge construction methods; annual and rotating Conference Proceedings from congresses and symposia (San Jose 2024, Tokyo 2025, Ghent 2025, Copenhagen 2026, Incheon 2026, Guwahati 2027, Milan 2027); Young Engineers Colloquium reports; an e-learning Academy; and the annual IABSE Awards program. Underlying technology is a conventional SaaS-based operating stack: WildApricot for member database management, Stripe for payments, Clarivate/ScholarOne for peer review, AWS for newsletter distribution, Google Analytics for traffic analytics, and YouTube and social platforms for member engagement and content distribution.

IABSE's business model is a hybrid membership, publishing, and event-driven association model. Revenue is generated through age-segmented annual membership subscriptions (Student 20 CHF, Young Engineer 105 CHF, Individual 235 CHF, Senior 150 CHF, Collective 635 CHF, with reduced pricing for residents of low-GNI countries), publication sales in both ePDF and print formats across the Bulletin series and Conference Proceedings (priced roughly 39-250 CHF per title, with member discounts), conference and symposium registration and sponsorship fees from rotating international events, and advertising across SEI and digital channels. Governance is exercised by elected leadership and technical committees (six Commissions, Task Groups, SEI and Bulletin Editorial Boards, Academy and E-Learning Boards, YEC Board), with the Executive Director function historically held by Alain Golay (1974-2005). Operations are run from a small 1-10 person secretariat in Zurich, with the IABSE Foundation providing supplemental funding and the Liaison Committee coordinating joint work with other international engineering associations.
