How high must the staircase rise vertically? Staircases consist of a number of steps with landings at suitable intervals to provide comfort and safety for the users. <> The stringers are notched so that the risers and treads fit into them. �ˆ'W��x��Hy�"�[�j�&���G+��Z��[� ArchDaily 2008-2020.

Although BIM software simplifies this process, it's always important to understand the restrictions and the underlying concepts. <> For this design, three main factors must be taken into account: It's important to be clear about where the staircase will begin and where it will end at the upper level, according to the flows that have been resolved in the plan. When inserting the values in the previous formula, its total circumference will be 6.28 m. Using the useful line, you will see that the calculated length is 4.18 meters where people will step on. Although the minimum radius to be considered in a helical staircase is 70 centimeters, you should always give preference to stairs with at least 80 centimeters radius. %���� The height, the diameter of the staircase, the diameter of the column and the step thickness are mandatory details. 5 0 obj The other dimensions will be calculated automatically.
