Lightweight exoskeleton steel portal structures
Significant demand for lightweight portal type structures exists in most developing countries. These structures are used in a great diversity of applications, varying from domestic housing to small industrial buildings. In contrast to most existing lightweight portal type structures which are premanufactured to varying degrees of completeness in workshop environments, an alternative structural concept is proposed whereby the total structure is manufactured on site by mostly unskilled labour, using standard commercial cold-formed steel sections. The cladding material is employed as an integral structural component through the principles of stressed skin diaphragm action. The germ of the proposed concept can best be described as a monocoque principle analogous to an exoskeleton structure, in which standard commercial cold-formed steel sections are used in conjunction with alternative footings. The new concept has the potential of resulting in significant savings on lightweight portal building costs. In addition, the proposed concept is complemented by the potential creation of employment for the unskilled labour sector, therefore suited for developing countries.
