Section of reinforcement stair

This architectural drawing is Section of reinforcement stair. Behaviour and reinforcement of one-way staircase connected to slabs. Due to the continuation of the staircase to slabs at its base and top, negative bending moments are formed at the supports (upper fibers tension) and therefore rebars are required at the upper fibers at both ends. The purpose of the main bar is to transfer the bending load developed at the bottom of the slab to the beams. We discussed the difference between one way and two way slabs. In one way slab, the slab is supported at two parallel sides where main reinforcement will be placed. For more details and information download the drawing file.
