Introduction
Stringer beams are structural members that
Stringer beams when utilized in staircases can be designed either with two edge beams (simply supported) or with a central beam (double cantilever). Figure 1 illustrates a simply supported staircase on two edge beams and a staircase supported on a central stringer beam

Figure 2.0 illustrates the second flight of a staircase required to span 7.5m between supports. Adopting a staircase spanning longitudinally supported by beams at the supports is uneconomical as the waste of the stair would be very large resulting in a huge volume of concrete and quantity of steel required to control deflection. Stringer beams can thus be adopted in order to reduce bending moments and deflection requirement. For this case a central stringer beam (double cantilever) type will be designed

The staircase is idealised as a T- section therefore the stringer beam is designed as a flanged beam and the waste of the staircase as spanning transversely (like a cantilever). Transverse beams will be required to support the stringer beam. These transverse beams are designed as carrying point loads from the stringer beam at midspan.
