Waist slab staircase definition. The stair is either cast with the steps making one unit or it is created by beams holding the steps. Waist slab or stair slab it is a slab provided just below the going along the length of stair to ensure proper strength and serviceability to the the staircase. Use diameter bar 10 mm. Stair slabs which are continuous and constructed monolithically with their supporting slabs or beams can be designed for a bending moment of say fl 10.

M1 bar spacing depends on structural designing. The width of staircase is 1500 mm the thickness of landing is 150 mm and the waist thickness h is 150 mm. In this waist the steps rest. For better understanding assume that spacing is 8 inches.

This term refers to a slab of the stair that is slanting from the floor slab to the landing slab. However in many instances the stairs are precast or constructed after the main structure pockets with dowels being left in the supporting beams to receive the stairs and with no appreciable end restraint the design moment should be fl 8.
