Abstract:
The cold-formed steel (CFS) framed shear wall with sheet steel sheathing is a code approved lateral force resisting system in low-rise residential and commercial buildings in North America. Current codes for CFS framed shear walls with sheet steel sheathing, including the analytical method and the tabulated values, supports the frame member’ thickness up to 54mil (1.372mm). This paper presents a research project aimed at improving the shear capacity for those shear walls by two methods: (1) thicker studs, (2) more field screws. Eight full-scale shear wall specimens are tested, including two different frame configurations and two test protocols. For each shear wall configuration, two specimens are tested. The results show that the CFS framed shear walls with sheet steel sheathing can significantly improve the shear capacity while using thicker studs and more field screws. In addition, the applicability of design provisions in AISI standards for higher strength CFS framed shear walls with sheet steel sheathing is analyzed. © 2021 Proceedings of the Annual Stability Conference Structural Stability Research Council 2021, SSRC 2021.
