Stair Tread - Horizontal Component of Load
Stair Tread - Horizontal Component of Load
(OP)
I'm doing some cantilever stair treads. The treads are a built up T and easily work for the vertical loads for serviceablility and strength. It's a residential stair so loading is relatively light.
I'm curious about the horizontal direction. Does anyone have any guidance on a load (or % of vertical load) that is used horizontally? I would think it's a fairly small component of the vertical, would 25% be conservative (75#)? I think it's fine but just wondering about the stair tread feeling like it's swinging under service conditions.

Timing has a lot to do with the outcome of a rain dance.

Having designed lots of stairs as a specialty engineer, I would be concerned with the handrail design on this one. And the torsion on your stringer and the end connections. That could be really difficult if the rest of your structure is wood!

sorry I meant to sa that that was the upper bound that I would expect. 20% sounds reasonable to me.
