Inelastic performance of cold-formed steel strap braced walls

Inelastic performance of cold-formed steel strap braced walls. Al-Kharat, M. & Rogers, C. Journal of Constructional Steel Research, 63(4):460 - 474, 2007. Inelastic;Seismic response;Strap brace;

Paper abstract bibtex

The inelastic performance of sixteen 2.44 m×2.44 m cold-formed steel strap braced walls was evaluated experimentally. The performance was affected by the holddown detail, which in many cases did not allow the test specimens to reach or maintain a yield capacity and severely diminished the overall system ductility. "Test-based" Rd × Ro values of 3.65, 2.11 and 1.72 indicate the low ductility levels, which were not adequate to warrant the use of a seismic response modification coefficient of R = 4.0 in design. Capacity design of the SFRS elements must account for the overstrength of the strap material. © 2006 Elsevier Ltd. All rights reserved.
