RE: Curved GLB

[Subject Prev][Subject Next][Thread Prev][Thread Next]
If you use a tie rod, it will become a point of restraint as the arch tries to deflect.  Therefore the tie rod will have to resist the full static thrust load of approximately (w * L squared) / (8 * H).

Im working on a project with curved GLB roof framing, ~16 span, 5o.c. w/ joists hung btwn them.  The architect is expecting a tie rod at plate level, but Im wondering how to calc the thrust at the base of these things.  Considering how theyre manufactured, it seems like there should be a lot less horizontal force at the plate than a simple statics analysis would indicate.
