Abstract

An AISI sponsored research project on the performance of 6 feet wide cold- formed steel (CFS) framed shear walls with single sided steel sheet sheathing is recently completed at the Un iversity of North Texas. This research project is aimed at determining the required seismic detailing for 6 feet wide 8 feet high CFS shear walls using two steel sheets, one is 4 feet wide, and the other is 2 feet wide. Both monotonic and cyclic tests are conducted and various parameters in the framing and sheathing details are considered in the test program. Those parameters include framing member thickne ss (33 mil, 43 mil, 54 mil), framing member size (3.5 inches, 6 inches), st eel sheet thickness (30 mil, 33 mil), fastener size (No. 8 and No. 10), sheet joint configuration, and the option in bracing and blocking. This paper presents the testing details, test results, and analyses on the performance of 6 feet wide CFS framed shear walls. Recommendations for framing and sheathing are provided in order to achieve satisfactory seismic performance. The nom inal shear strength for the tested shear wall configurations are also presented in this paper.
