RE: Axial load on stair stringers?

[Subject Prev][Subject Next][Thread Prev][Thread Next]

Re:; Metal Stairs Manual, National Association of Architectural Metal
Manufacturers, Chicago.

The NAAMM ignores tension and compression and assume the wall and face
stringer are bending elements with no axial load.  I have designed very
wierdly configured stringers for compression in the past, but the vast
majority are bending only.
