Re: Scissor Truss

[Subject Prev][Subject Next][Thread Prev][Thread Next]
As long as the top chord is braced I wouldn't see any need for the lower chord to be braced unless the difference between the angles of the chords is very small and the roof pitch is low which would approach a balanced design and reduce stability.
     If the structure is in a high seismic risk zone a brace to a joint in tension could be detrimental.

I should have been more specific.  The bracing is horizontal from truss to truss.  There is a vertical member at the center line of the truss.
