Thanks for you reply BigWallop. I forgot to put a link in to show the
typr of stairs. Here it is:

you can see - the steps fit together like vertebrae of a spine.

I also need the stairs to wind round through 180 deg like a spiral.
does this not have an impact on the loading? I wondered if anyone has
a weight for the staris or even a knowledge of a reasonable assumption
for loading ON a stair (i.e. reasonable from the point of view of the
building control inspectors.
