Steel lintel beam

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I understand.

Assuming the roof system bears directly on the beam/lintel, WHEN does it
become laterally braced?  It certainly is not braced  immediately after it
is set in place, carrying only its own dead load.  And it is probably not
braced when the steel joists are in place, before the deck is installed.

So, my question is either:

     "should this loading condition be considered during design?"
                                              or
     "should the contractor be advised that the beam must be temporarily
braced until the assembly is complete?"

I'll be the first to admit that I have not routinely checked beams and
lintels for their unbraced condition with construction loads applied.  I am
presently re-thinking my design methods.  I haven't had any reported
problems, but then maybe I've just been lucky.
