Some suppliers specifying engineered beams (using beam calculator software) will often attribute a very significant point load on a ceiling beam having a required brace running from a point on the beam to a ridgeboard to hip rafters connection.
I recently acquired a calculation where such a point load was deemed to be 12,000 lbs on a 28' wide garage having a 10/12 pitch roof.
Some claim true rectangular or square hip roof structures are self-supporting.
If hips are self-supporting, why are braces required? To what extent do the opposing forces of a symmetrical hip roof system relieve the point load resulting from a roof brace?
In the above example, the supplier specified a humongous beam that did not appear justified.
I know . . . require engineering. Any other comments?
