The International Colloquium on Stability and Ductility of Steel Structures (SDSS 2025)

The 2025 edition of the International Colloquium on Stability and Ductility of Steel Structures (SDSS 2025) will be held at the Universitat Politècnica de Catalunya (UPC), in Barcelona (Spain), on 8-10 of September. The successful series of SDSS colloquia started in Paris, France (1972), and had the last five editions held in Lisbon, Portugal (2006), Rio de Janeiro, Brazil (2010), Timisoara, Romania (2016), Prague, Czech Republic (2019) and Aveiro, Portugal (2022).

The series of International Colloquia on Stability and Ductility of Steel Structures that has been supported by the Structural Stability Research Council (SSRC) and by the European Convention for Constructional Steelwork (ECCS), aims at providing a forum for discussion and dissemination, by researchers and designers, of the most recent advances in theoretical, numerical and experimental research in the field of stability and ductility of steel and composite steel and concrete structures. Special emphasis is always given to new concepts and procedures concerning the analysis and design of steel structures and to the background, development and application of rules and recommendations either appearing in recently published codes or specifications or about to be included in their upcoming versions.

The SDSS 2025 participants will be able to become familiar with the most recent achievements in the advancement of knowledge and application in the above fields, share the latest trends and developments and exchange ideas on current and future research needs.

It is our great pleasure to invite you to Barcelona (Spain) for the 2025 edition of the International Colloquium on Stability and Ductility of Steel Structures on 8-10 of September 2025.
