Abstract
Concrete filled stainless steel columns (CFSSC) combine the advantages of both concrete and stainless steel columns to offer a durable and high load carrying solution. Concrete-filled stainless steel columns are used in many engineering applications including: columns, beams, trusses and many forms of structural components.
The stainless steel grades most commonly encountered in construction industry are Austenitic, Duplex/Lean duplex and Ferritic grades. Austenitic stainless steels are generally selected for structural applications which require a combination of good strength, corrosion resistance, formability and weldability. Where higher strength and/or higher levels of corrosion resistance are required, the duplex stainless steels or lean duplex stainless steels, with lower material cost, are most suitable. Ferritic stainless steels, containing no or very low nickel content, provide a cost effective solution to applications where strong and moderately durable structural elements with attractive metallic surface finish are required.

| Description | The focus of this project is on the behaviour and design of cold-formed stainless steel hollow section structural components in fire conditions. Currently, codified methods for fire design of stainless steel structures are based largely upon those for carbon steel structures. The main aim of this research study was to develop safe, reliable and efficient design methods for stainless steel structural elements that are in line with the observed actual response of the stainless steel structures at elevated temperatures. |
| Exploitation Route | The proposed revisions were shown in the project to lead to a more accurate and reliable determination of resistance of stainless steel columns and beam-columns members at elevated temperatures, enabling a more efficient use of the material in structural applications. |
