Welcome to CIDECT

CIDECT is dedicated to designers and architects of steel and composite structures, researchers, students and generally interested people. CIDECT provides a broad range of technical assistance, design examples and information for economic construction using hollow sections.  

What it means

CIDECT is an abbreviation for: Comité International pour le Développement et l´Etude de la Construction Tubulaire This can be translated roughly with: Committee for International Development and Education on Construction of Tubular structures.

Who we are

CIDECT is an international association of leading manufacturers of structural hollow sections and pipes. Main objective is to expand and summarize knowledge, by means of funding research and design guides on structural hollow sections and promote their application in steel construction and engineering. For your benefit, cooperation with leading scientists, researchers and practitioners provides consolidated knowledge to stimulate the development of design codes and guidelines worldwide. You benefit from longterm maintained contacts and exchanges between the producers of the structural hollow sections (HSS), the steel construction companies and numerous architects and engineers throughout the world. CIDECT promotes structural hollow sections (HSS) usage for good engineering practice and suitable architecture by providing information, contacts, organizing conferences etc. 1962 CIDECT was founded as non-profit association. Until today CIDECT is operated by its members only, granting that almost all funds are used for research topics. In total more than 200 international research projects and a range of design guides had been funded or co-funded. Typically published results based on CIDECT reports are widely accepted by experts and practitioners. Finally it should be mentioned that CIDECT Design Guides have been used and accepted worldwide and are a foundation for the majority of modern standards like e.g. ANSI/AISC or Eurocode.


Are you involved in architecture, design or execution of hollow section (HSS) structures? You benefit from:
  • practical assistance through our design guides
  • direct contact to internationally renowned experts
  • a worldwide acting non profit platform to provide profund independent answers to your challenges
  • results of several funded research projects every year

Technical Focus

The technical activities of CIDECT have centered on the following research aspects of hollow steel section design:
  • Buckling behavior of empty and concrete filled columns
  • Effective buckling lengths of members in trusses
  • Fire resistance of concrete-filled columns
  • Static strength of welded and bolted joints
  • Fatigue resistance of joints
  • Aerodynamic properties
  • Bending Strength
  • Corrosion resistance
  • Workshop fabrication
The results of CIDECT research form the basis of many national and international
