Structural Systems with Hollow Flange Sections in Cold-Formed Steel

点击翻译按钮获取中文摘要

Palmer Tube Mills have created a new range of hollow flange sections in cold-formed steel manufactured with the unique dual resistance welding process for use in the construction industry. The new sections combine the properties of hot-rolled open sections and cold-formed sections to create more structurally efficient sections. These new sections experience some unique and specific failure modes that are not considered in current design standards. This project will investigate these failure modes to devise efficient and safe guidelines for their structural design. The project will also develop new structural systems to utilise the unique properties of these sections.
