Cyclic bending behaviour of hollow and concrete-filled cold-formed circular steel members

This thesis is concerned with the analysis and design of thin-walled tubular members made of cold-formed circular hollow sections (CHS). In particular, it deals with hollow and concrete-filled tubes in bending. The background information required to provide the basis for developing new design rules for empty and void-filled cold-formed CHS in bending was reviewed. Existing design rules in Australia, Europe, North America and Japan were examined to highlight the gaps and lack of appropriate design models for such structures. [...]
