First, take the dimensions of the stairwell opening. A spiral staircase has a 100mm smaller diameter than the given stairwell opening. (As per BS5395-2 1984).This provision makes the stairs to fit comfortably in the given space. Fig.2. Stairwell Opening Layout However, the design of these staircases requires careful attention so that you can prevent an uncomfortable or dangerous outcome. Although BIM software simplifies this process, it's always important to understand the restrictions and the underlying concepts. Spiral staircases can adopt different structural configurations

RE: Spiral stair design dik (Structural) 14 May 10 09:18 If a freestanding spiral, you may not have the torsional stiffness to do it well and it could be bouncy Free-standing staircase structures are complex in analysis and design, but with finite element analysis packages, simple solutions can be easily obtained as shown in this post. The most widely available manual solution for the analysis of free-standing staircases was developed by Cusens and Kuang (1966) using the strain-energy principles Spiral staircases can adopt different structural configurations. The most common ones have a circular format with a central mast from which the steps are fixed. Save this picture

• The minimum width of stair (Fig.9.20.2a) should be 850 mm, though it is desirable to have the width between 1.1 to 1.6 m. In public building, cinema halls etc., large widths of the stair should be provided. Structural Systems Different structural systems are possible for the staircase, shown in Fig. 9.20.3a, depending on the spanning direction Designing the Staircase The critical design characteristic of any staircase is based on the fundamental calculation of total rise and total run. Total rise refers to the vertical distance a stair must climb from finished floor on the lower level to finished floor on the upper level.

VERIFY ALL SETTING OUT DIMENSIONS WITH THE ENGINEER/ARCHITECT. VERIFY LOCATION AND DIMENSIONS OF CHASES, INSERTS Spiral Stairs follow a helical arc, and the treads radiate around a central pole. They are often found in industrial contexts, and the reduced tread width allows for a very compact design. However, this can be a disadvantage as it can be very steep.
