REVIEW: STRUCTURAL STAINLESS STEEL SEISMIC FORCE-RESISTING SYSTEMS

This paper presents an overview of design considerations for structural stainless steel seismic force-resisting systems (SFRS). While stainless steel is widely utilized for its corrosion resistance and aesthetic appeal in various structural applications, its seismic design in the U.S. remains underdeveloped due to the absence of dedicated U.S. design standards. This research addresses the mechanical properties, cyclic performance, and seismic behavior of austenitic and duplex stainless steels, highlighting their significant strain hardening, ductility, and toughness under cyclic loading. Comparative studies with carbon steel indicate the potential for stainless steel SFRS to achieve equivalent or superior seismic performance. Preliminary recommendations for adapting existing seismic design provisions, such as ASCE 7 and AISC 341, to stainless steel structures are proposed, covering material factors, width-to-thickness and stability bracing requirements, and system-specific seismic design parameters. These guidelines aim to bridge existing gaps and encourage broader adoption of stainless steel in seismic applications, while identifying future research needs for comprehensive standards development.
