Hand Rail Post Embedment Depth
Hand Rail Post Embedment Depth
(OP)
I've been doing stair & railing calcs lately (yeehaw) & need to know how to calculate the embedment depth required for the steel posts in concrete slabs. Often it's a thin concrete floor slab, 4" or so. I've looked at PCI Design Handbook EQ 6.9.1, but I don't know if this is applicable to an unreinforced, or just S&T slab. What would be used for the effective width of the compression block, b? Is there a minimum cover between the base of the tube & the bottom of the slab? The forces are so low, but in submitting calcs, need to show something?
Any advice?

Most common failure in handrails (outside moment at welded connection) is localized crushing or excess moment of aluminum post tubes at top of embedment. Steel is not usually an issue, since most stair and rail fabricators use 50 ksi material.
