Calculates stair dimensions: rise, run, and number of steps.
The staircase calculator works out the number of steps, the flight length, the concrete volume, and the formwork area for a monolithic reinforced-concrete staircase.
Steps = ⌈storey height / riser height⌉ Flight length = steps × tread depth Concrete = volume of the inclined slab + volume of the steps
Storey height 3 m, step 17 × 28 cm, width 1 m. Steps: ⌈3 / 0.17⌉ = 18. Flight: 18 × 0.28 = 5.04 m. Concrete: 1.13 m³.
