What is a Spiral Staircase?
A spiral staircase is a circular staircase that rotates around a central axis. It is widely used in modern architecture where space-saving design is required.
How Spiral Staircases Are Designed
The design depends on total height, step size, and radius. Each step is evenly distributed around a 360° circle.
Key Formulas Used
- Number of Steps = Total Height ÷ Step Height
- Step Angle = 360° ÷ Number of Steps
- Tread Length = (2 × π × Radius) ÷ Steps
Why This Calculation is Important
- Ensures safe stair design
- Prevents uneven steps
- Helps architects and builders
- Improves comfort and usability
Common Applications
