Recent Research Advances in High-Performance Steel Tubular Members: Material Properties, Stub Columns, and Beams

Abstract

This paper presents recent advances in research on high-performance steel tubular members, including beams and columns. The term high-performance steel has been used for steels that have unparalleled characteristics such as high strength, cold formability, corrosion resistance, and ductility. Stainless steel (SS) and high-strength steel (HSS) are classified as high-performance steel. In the context of this paper, high-performance steel refers to SS and HSS, where HSS is with a nominal yield strength equal to or higher than 690 MPa. This paper initially illustrates the applications of high-performance steel as a construction material for buildings and infrastructures. Subsequently, the material properties of high-performance steel with constitutive models in response to the stress–strain curves are summarized. Furthermore, this paper reviews research on the structural performance of high-performance steel stub columns and beams and presents the associated design equations. Finally, insights into future work on the structural behavior of high-performance steel to promote its widespread use for building and infrastructure construction are provided.
