Pre-engineered metal building foundations

[endz87]

Hello All,

Hoping someone can help me out. I understand on a typical gabled pre-engineered metal building frame that there are outward thrusting forces at the column bases and that you counteract that by using either hair pins or tie-rods between columns. My question is, do those same outward thrusting forces exist on a single slope framed building?

Any comments would be greatly appreciated! Thanks!

Yes. Less so, but still present. The premise of a pre-engineered metal building (PEMB) frame is that the frame is rigid, but the connections at the foundation are pinned. This leaves lateral thrust forces that must be resisted.

It doesn't have to be a "pre-engineered" building to have lateral forces at the base. A rigid portal frame typically has both vertical and lateral forces at both supports, otherwise the rafter would be just a simple beam.

I agree with Ron and Mokie here - been doing foundations for these animals for 33 years now... off and on.
