Carbon Steel Pipe

[teddyt11]

Hello,

I am just trying to test a railing by the OSHA specifications. The railing is ASTM A53 grade A Sched 40 Carbon Steel. The railing is 6 feet long between posts and 42 inches high. The nominal weight is 2.72 lb/ft, yeild strength 30 ksi, tensile strength 48 ksi, and allowabale stress 22 ksi. The railing is supposed to be able to withold a 200 lb force in any direct except for up. Can someone help me figure out how to prove the the railing meets the specifications

Well, you didn't give the member size (just weight) so it's pretty hard. But if you put a 200 lb. lateral load on your top rail in the center of a 6'-0" span you can check that member in bending. And if you put that load at the top of one of your posts, you can check that as a cantilever beam. Then check your anchorage and you're done.
Are you really a structural engineer?
