Re: Lateral bracing of steel trusses

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Not sure of any references, but we had a thread similar to this a while
ago.  One comment that was made was that the webs are typically
designed as pinned-pinned members.  The bottom chord has to be
rigid enough to so that webs in compression can act as designed.
This is why bracing of the bottom chord is required, even if there is
no uplift.
