Abstract

The paper presents the recent research and development of cold-formed steel structures performed by the author. The topics that are summarised here include materials behaviour, sections with stiffeners, sections strengthened by fibre-reinforced polymers, built-up sections, oval hollow sections, high strength steel sections and modular integrated construction using cold-formed steel sections. Cold-formed steel sections with steel grades ranging from 350 to 1100 MPa were used. It should be noted that the current design rules for cold-formed steel structures are limited to steel grades up to 700 MPa. Design rules for cold-formed high strength steel members with steel grades higher than 700 MPa have been proposed by the author. The material properties of cold-formed high strength steel have been examined in the research summarised in the paper, specifically a series of coupon tests at ambient and elevated temperatures as well as post-fire condition. A stress-strain model for cold-formed high strength steel has been proposed.
