Part 1: Architect’s Guide 1 - 15 Variable profile sections can deliver a certain architectural dynamism to the design of these columns. Formed from standard sections or plates, these columns have as their main characteristic variable lengthwise dimensions which can optimize their structural function. Since steel works equally well in tension as in compression, for functional (to avoid obstruction) or architectural reasons, a hanger or tie rod may be preferred to a column, in order to hold a beam and cross a floor space without a point of support. Figure 4.3 Structural arrangement with hangers 4.1.3 Beams Beams spread the vertical loads and are mainly subject to bending. The beam section must therefore present sufficient stiffness and strength in the vertical plane. There are many different types of beam, see Table 4.2. Amongst these, composite beams are particularly well suited to multi-storey buildings. When combined with steel, the concrete works in compression and the steel (mainly) in tension: the outcome is a system that offers good mechanical performance, both in terms of resistance and stiffness.
