Steel Buildings in Europe

Part 2: Concept Design 2 - 4 A truss building may also be designed as rigid in-plane, although it is more common to provide bracing to stabilise the frame. Other forms of construction Built–up columns (two plain beams, connected to form a compound column) are often used to support heavy loads, such as cranes. These may be used in portalised structures, but are often used with rigid bases, and with bracing to provide in-plane stability. External or suspended support structures may be used, as illustrated in Figure 1.6, but are relatively uncommon. Figure 1.2 Multi bay portal frame structure
