Staircase is an important component of a building providing access to different floors and roof of the building. Special attention has to be paid to reinforcement detail at opening joints, as shown in Figure 10.8. concrete beam with top and bottom reinforcement as well as middle torsion reinforcement. Now we will see the other loads coming on the stairs. At the end lower the stair supported by a beam and continuous with the floor slab. The reinforced concrete stairs should be designed generally similar to reinforced concrete slabs, except as indicated otherwise. During the final phase of the positioning of the staircase’s reinforcement, the lower rebars (in red color) are tied to the distribution bars to their proper position. Layout the pattern on the skirt board. Drawing shows the arrangement of main reinforcement (ties, stirrups) and the secondary steel (transverse direction).
