Beams span between supports to carry lateral loads which are resisted by bending and shear. However, deflections and local stresses are also important. Beams may be cantilevered, simply supported, fixed ended or continuous, as shown in Figure 4.l(a). The main uses of beams are to support floors and columns, carry roof sheeting as purlins and side cladding as sheeting rails.
