Design of Common Structural Forms.
2 Beam and column The cross-section shown in Fig. 1.4 is undoubtedly the simplest framing solution which can be used to provide structural integrity to single-storey buildings. Used predominantly in spans of up to 10m, where flat roof...
3 Truss and stanchion The truss and stanchion system is essentially an extension of the beam-and-column solution, providing an economic means of increasing the useful span. Typical truss shapes are shown...
4 Portal frames By far the most common form of structure for single-storey structures is the portal frame, the principal types being shown in Fig. 1.20. Spans of up to 60m can be achieved by this form of construction, the frame generally comprising hot-rolled...
5 Tied portal The tied portal, a variation of the portal frame, is illustrated in Fig. 1.26. Economy of material can be achieved, albeit at the expense of reducing the allowable headroom of the building, by provision of a tie at eaves level. Under vertical loading, the...
6 Stressed-skin design In addition to providing the weathertight membrane, the steel sheeting can also be utilized as a structural element itself. Correct detailing of connections between individual cladding sheets (and their connections to the support steelwork) will...
7 Purlins and siderails Due to the increasing awareness of the load-carrying capabilities of sections formed from thin-gauge material, proprietary systems for both purlins and siderails have been developed by several manufacturers in the United Kingdom. Consequently, unless a...
8 Cladding In addition to visual and aesthetic requirements, one of the fundamental roles of the cladding system is to provide not only the weatherproofing for the building but also the insulation requirements suited to both the building and the environment. Cladding...
