Light gage metal as a principal component of structural systems has been widely used for the last 2-3 decades. The knowledge of its behaviour and of the design theory has vastly advanced since the 1950's when this author was working at Cornell nn the research of light gage structures.
Use of conventionally interconnected light gage metal panels in a complete structural system presents two difficulties: I} buckling out of plane of a panel, and 2} continuity (i.e. resistance to bending and shear) through the junction of light gage panels. This paper presents economical techniques to cope with these difficulties. The techniques have been developed and used by the author in several successfully constructed projects.
It is hoped that this presentation, with the examples cited, will point to the two not yet fully utilized advantages of light gage structures. Both potentials have been realized through imaginative addition of other materials than light gage steel. These two potential uses are a) reinforcement of light gage panels against buckling, and b) the imparting of continuity through interconnected light gage panels. The first could be achieved economically through readily available plastic or similar panels glued to the light gage panels, while the second, through the use of high strength cables.
