👉Preparation of Bar Bending Schedule (BBS) for Staircase

🪧This diagram shows the step-by-step preparation of a staircase reinforcement schedule.

Floor height = 3000 mm

Riser = 150 mm

Tread = 300 mm

Landing width = 1200 mm

Total risers = 20

Risers per flight = 10

Effective steps per flight = 9

💫Key Calculation:

Horizontal run = 9 × 300 = 2700 mm

Total rise = 9 × 150 = 1350 mm

Slope length:

=SQRT(2700^2 + 1350^2)

🚧Purpose:

🧷The BBS helps calculate the number, length, shape, and quantity of reinforcement bars required for staircase construction, ensuring accurate steel estimation and proper reinforcement detailing.
