Steel Buildings in Europe

Part 1: Architect’s Guide 1 - 24 of the building must be considered carefully. An example of a cable stayed building structure is shown in Figure 3.20. Figure 3.20 Cable stayed roof beams of a storage facility Alternative configurations for a flat roof building are shown in Figure 3.21. Cable stayed configurations are most economical for spans between 30 m and 90 m. As most of the structure is outside of the building, maintenance costs can be high. Care must be taken in detailing the waterproofing where the stays pass through the cladding. 1 2 3 1 2 3 Roof beam Bending moment + ++ + Compression force -- - + Anchorage Tensile force ++ -- -- Figure 3.21 Comparison of the three main configurations for cable stayed structures The arrangement of the structure has a significant effect on the internal forces and therefore the member sizes. The building arrangement should be developed in collaboration with the structural engineer.
