The theoretical procedures employed in the structural analysis of stairs is the concept of an idealised line structure and when detailing the reinforcement for the resulting stairs, additional bars should be included to limit the formation of cracks at the points of high-stress concentration that inevitably occur. First/Second/Third Floor Slab Top Reinforcement plan. These components are reinforced with steel that give stability to the structure. The next phase includes the positioning of any necessary additional upper rebars followed by the placement of their distribution bars. 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. Reinforced Concrete Stairs Cross Section Reinforcement Detail This is a typical Reinforced Concrete Stairs Cross Section Reinforcement Detail, in CAD drawing that needs to be included alongside with every structural drawing that includes a concrete staircase to show correct reinforcement placement at the start, middle and landing part of the stairs. Slab reinforced with top U-shaped 'hairpin' top longitudinal reinforcement bars as well as transverse bars. RCC structure is composed of building components such as Footings, Columns, Beams, Slabs, Staircase etc. Self weight of finishes The self weight of finishes applied over the steps should be considered in the design. Drawing shows the arrangement of main reinforcement (ties, stirrups) and the secondary steel (transverse direction).
