1. Introduction
Current seismic analysis and design procedures for cold-formed steel (CFS) frame buildings focus on the strength of individual shear wall units [1], e.g., shear walls constructed with CFS steel members sheathed with Structural 1 plywood (4 ply), oriented strand board (OSB), gypsum board, or thin sheet steel or strap bracing. These building subsystems are designed using prescriptive procedures and tabulated values based on shear wall tests. Research efforts to characterize the response and develop numerical models for CFS lateral load resisting systems typically focus on the response of shear walls to push-over and cyclic tests (e.g., [2–4]). Specific guidance about energy dissipation or strength degradation for these systems and their components (e.g., drag struts, boundary chord studs) is not readily available. The goal of the research summarized in this paper is to experimentally investigate and then quantify the cyclic behavior, and energy dissipation characteristics of CFS axial members. This test data will be implemented in future CFS subsystem seismic numerical models as part of a larger ongoing multi-university research effort [5].
