Reinforced Concrete Staircase Section CAD Drawing with 6Ø16 and 5Ø14

Reinforced concrete staircase CAD drawing showing a detailed staircase section with structural reinforcement layout used in building construction planning. The drawing clearly illustrates the staircase cross-section, including step profile, landing slab, and inclined waist slab structure. Reinforcement details are marked with bar distribution such as 6Ø16 per meter and 5Ø14 per meter along the staircase slab to ensure structural strength and load distribution. The staircase section also shows step dimension alignment, stair flight connection, and landing support integrated with surrounding structural walls. Concrete stair slab thickness and reinforcement placement are carefully indicated to guide engineers in understanding the structural framework of the staircase.
