  • Seismic analysis of sheathing-braced cold-formed steel structures

The seismic behavior of sheathed cold-formed steel (SCFS) structures is characterized by the lateral response of shear walls. Basically, if cold-formed steel (CFS) structures are designed according to the ‘‘sheathing-design’’ methodology ...

  • Shear resistance of cold-formed steel framed shear walls

The cold-formed steel (CFS) framed shear walls using steel sheet sheathing is a code approved lateral force resisting system in residential and low-rise commercial buildings in the United States. The current design specifications in the US provide nominal shear strength for a limited range of CFS shear wall configurations in terms of sheathing thickness and wall aspect ratio. ...

  • Testing of cold-formed steel framed domestic structures

In common with many regions of the world which experience low to moderate levels of seismicity, the majority of domestic houses in Australia are not designed specifically to resist earthquakes. The Australian earthquake standard, introduced in 1993, includes domestic structures which are mostly light framed construction. ...

  • A Specific Procedure For Seismic Design Of Cold Formed Steel Housing

In the last years, the seismic performance of cold-formed steel (CFS) systems has been object of study by a large number of research teams. The main parameters influencing the system behavior under horizontal loads have been defined and the possible mechanisms of collapse have been identified. Therefore, at the moment, the development of upgraded specifications and design tools that could be readily used by designers is a must. For these reasons, this paper aims to propose a seismic design procedure that allows the shear wall components to be defined in a few steps. The procedure is based on the recognized assumption that the best performance of a CFS shear wall is achieved when the sheathing-to-stud fastener failure is reached. Moreover, it accounts for the results of previous studies that defined the relationship between the behavior of shear walls and fastener spacing. Hence, by defining three nomographs, the proposed procedure allows the sheathing-to-stud fasteners and all the other shear wall components to be defined. The latter is determined in accordance with capacity design criteria. Finally, the applicability of the presented procedure is verified through a case study. ...
