Cold-Formed Steel Back-to-Back Header Assembly Tests. Final Report

摘要

Light-gauge steel-framing has recently become recognized as a viable alternativeframing method for residential construction in the United States. With this recognition, the need to efficiently design for lateral loads produced by winds and seismic forces has prompted research to fill this need. This paper presents monotonic load tests of 40-foot long, cold-formed steel-framed shear walls with openings. Lateral force resistance and displacement response are discussed. Predicted capacities, using an empirical design approach known as 'Perforated Shearwalls,' are compared with measured capacities. Also, ultimate capacity, initial stiffness, and energy dissipation are highlighted. Findings from these tests indicate that light-gauge steel-framed shear walls are a viable alternative for residential construction in high wind and seismic regions. the report recommends that additional testing be done to building on this study's findings and suggests future topics of study.
