Spiral Staircase with Five Radii

Stair Steel Detailing

The Challenge

The project began with determining key parameters: the spiral staircase height, the number of treads, and the five radii, which needed to transition smoothly into one another. The main challenge was ensuring accurate calculations and creating seamless curves so the staircase would be both functional and visually striking.

Another significant hurdle was designing reliable support points. These not only had to stabilize the structure but also handle the load effectively, especially at radius transitions, which demanded precise calculations for placement.

Our Expertise

To calculate the spiral’s geometry, we used parametric equations where each point was defined by the rotation angle and the current radius. For smooth transitions between radii, we applied linear interpolation and trigonometric functions, achieving a harmonious shape without abrupt changes.

Special attention was given to support points, which were carefully analyzed for weight distribution. We added extra anchoring points at radius transitions, ensuring stability and load-bearing capacity. This involved precise calculations of coordinates and tilt angles to meet structural and aesthetic requirements.

The Result

The final spiral staircase design exceeded expectations, with fluid curves and a solid support system seamlessly integrated into the structure. It’s a perfect balance of engineering precision and architectural elegance, demonstrating our ability to tackle even the most intricate challenges.

This project highlighted how combining math, engineering, and creativity can lead to extraordinary outcomes. We’re proud to have brought this unique design to life!
