Angle Guard rail Posts
Angle Guard rail Posts
(OP)
On a current project I am trying to use L2x2x3/8 as posts for a guard rail on a crane based on our stress limits the post fails under the full 200lbs OSHA requirement. My question is does the NAAMM Nomogragh also apply to angles as post or is there another way of determining the load applied to a single post?

Any particular reason for using L2 x 2 x 3/8. Seems like an odd size. Thicker than normal guard posts, but smaller in length. It's Z value is 0.629 in^3. A L3 x 3 x 1/4 has a Z value of 1.02 in^3

The way the OSHA requirement is worded, basically, the handrail shouldn't fail at that design load, doesn't mean it can't be overstressed. Per the building codes, it'd normally be different.

The greatest trick that bond stress ever pulled was convincing the world it didn't exist.

Bagman, the graph is in a document titled Pipe Railing Systems Manual, so you could understand someone assuming it applies only to pipe members.

IFRs: the angles does not pass the load calculation when run as a flagpole.
So I am searching for a method (other then computer based program) to show that angle will work under a railing condition and through all my searching have come up with nothing.
