4. Width of landing: It should be 150mm, more than the width of stair.
5. Winders or kite steps: Odd shaped steps should be avoided and incase found necessary. These should be
provided at the start of a stair.
6. Han-rails: It should be 750 to 850 mm in height from the top of respective step or landing.
7. Step proportions: The size of rise and tread in a stair should be kept uniform through out the whole stair.
Stairs are consist of smooth vertical & horizontal surfaces structural members that provide the transportation and connection between floors or structural parts having different elevation. Arrangement the geometrical shape of stair depends on functional usage, number of floor and size of the staircase space.One of the most useful structural details when designing for reinforced concrete.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.A stairway, staircase, stairwell, flight of stairs, or simply stairs, is a construction designed to bridge a large vertical distance by dividing it into smaller vertical distances, called steps.
