Preface Structural Steel work Design to Limit State Theory :
These three types cover many of the uses of steel frame buildings such as factories, warehouses, offices, flats, schools, etc. A design for the lattice roof building (Figure 1.1(a)) is given and the design of the elements for the braced multi-storey building (Figure 1.1(c)) is also included. Design of portal frame is described separately in Chapter 9.
The building frame is made up of separate elements—the beams, columns, trusses and bracing—listed beside each section in Figure 1.1. These must be joined together and the building attached to the foundations. Elements are discussed more fully in Section 1.2.
Buildings are three dimensional and only the sectional frame has been shown in Figure 1.1. These frames must be propped and braced laterally so that they remain in position and carry the loads without buckling out of the plane of the section. Structural framing plans are shown in Figures 1.2 and 1.3 for the building types illustrated in Figures 1.1(a) and 1.1(c).
Various methods for analysis and design have been developed over the years. In Figure 1.1, the single-storey structure in (a) and the multi-storey building in (c) are designed by the simple design method, while the portal frame in (b) is designed by the continuous design method. All design is based on the newly revised limit state design code BS 5950-1: 2000: Part 1. Design theories are discussed briefly in Section 1.4 and design methods are set out in detail in Chapter 2.
