If you’re unfamiliar with cold-formed steel (CFS) framing or simply haven’t used it in a while, you may have several questions: What is it? How can I use it? Why should I use it? CFS certainly isn’t a new building material. It actually has been used in North America for over 100 years. Because of its light weight and durability, it can be used in a range of applications — from interior, non-loadbearing partition walls to structural members in mid-rise and multi-family buildings. Whatever your current level of knowledge, consider this eBook a primer on all things CFS framing. In it, you’ll learn what CFS is, how it can benefit a construction project, the basics of designing with and ordering CFS, and training options for expanding your CFS knowledge.
Infill walling is the generic name given to a panel that is built in between the floors of the primary structural frame of a building and provide ssupport for the cladding system. Infill walls are considered to be non-load bearing, but they resist wind loads applied to the façade and also support their own weight and that of the cladding. Light steel walls using C sections are increasingly used as infill walling within both steel and concrete framed buildings, and have largely replaced masonry or timber alternatives.
An important feature of light steel infill walls is that the size and thickness of the light steel C sections can be varied depending on the height of the façade wall and the wind loads acting on it. Large windows, parapets and other architectural features are made possible. Infill walls are generally installed onsite as individual elements that are pre-cut to length but they can be pre-fabricated as large panels with the cladding already attached.
The same components may be used for internal separating walls, but here the main issues are fire resistance and acoustic insulation rather than resistance to loading. A nominal internal pressure is used in the design of internal separating walls.
