In an RCC stair slab without stringer beams, spanning onto the edge of a landing slab that spans parallel with the risers, what is the effective span of the stairs if the landing width on both sides is X > 1 m and Y > 1 m? (Where G = going of stairs)

According to IS 456:2000, the minimum percentage of high yield strength deformed (HYSD) bars in an R.C. slab compared with total gross concrete area is:

As per standard civil engineering provisions (IS 456), the nominal clear cover (in mm) to main reinforcement bars in footings, columns, beams, and slabs are respectively:
