Design examples of concrete-filled steel tubular (CFST) hybrid structures in accordance with ISO 16521

Exemples de conception de structures hybrides en tubes d'acier remplis de béton (CFST) conformément à l'ISO 16521

Abstract / scope

This document provides design examples of concrete-filled steel tubular (CFST) hybrid structures in accordance with ISO 16521.

This document includes the design calculation of major structural types in ISO 16521, i.e., trussed CFST hybrid structures, concrete-encased CFST hybrid structures. The design examples cover the major loading cases for the structures and follow the design procedure presented in ISO 16521:2024, Clause 6.
