Calculation method of loft stairs
Mar 08, 2025| Calculation method of loft stairs mainly includes the following aspects:
Number of stair steps and height:
Number of stair steps: The number of stair steps (N) can be calculated by dividing the total height (H) by the step height (h_t), and the formula is: N = H / h_t.
Step height: The step height (h_t) can be calculated by dividing the total height (H) by the number of steps (N), and the formula is: h_t = H / N.
Step width: The step width (w_t) can be calculated by dividing the total length (L) by the number of steps (N), and the formula is: w_t = L / N.
Total height and length of stairs:
Total height of stairs (H): H = height of each floor (h) × number of floors (n).
Total length of stairs (L): L = length of each floor (l) × number of floors (n).
Staircase area:
Staircase area (A): A = total length of stairs (L) × width of each floor (w), that is, A = L × w.
Staircase slope:
Staircase slope (i): i = step height (h_t) / step width (w_t), the formula is: i = h_t / w_t.
Other parameter calculation:
Staircase landing length (P): P = step width (w_t) × number of platforms (m), the formula is: P = w_t × m.
Staircase landing height (p_h): p_h = height of each floor (h) / (number of floors + 1), the formula is: p_h = h / (n + 1).
Staircase handrail length (F): F = total length of stairs (L) + 2 × length of staircase landing (P), the formula is: F = L + 2P.
