designing a staircase with floating landing

designing a staircase with floating landing

RE: designing a staircase with floating landing

If you have no supports on any sides of your landing, I can see 2 options but they will produce large torsional moments on your supporting beams. Option 1: model each upper and lower staircase as a cantilever. Assign the landing to either cantilever. Option 2: model the upper staircase as simply supported between the upper floor and landing. Design the lower staircase and landing as a cantilever. There is also option 3: continuously harass your architect until he or she agrees to let you put in hangers or supports for the landing.

RE: designing a staircase with floating landing

Agree with Motor City. I've only seen a handful of stairs with an unsupported switchback landing. Puts large torsion on the supporting structure

All I know is P/A and Mc/I

RE: designing a staircase with floating landing

It's a truss.

RE: designing a staircase with floating landing

Can you not design the stairs as continuous through the landing? That would take out any torsional moments to the supporting beams.
