Re: Scissor Truss

[Subject Prev][Subject Next][Thread Prev][Thread Next]
The "classic" scissor truss configuration is with a vertical brace from the peak of the bottom chord to the joint of the top chord.  There will be a tensil force in the vertical member so it is required.  The difference between the slopes of the bottom and top chords from horizontal determines the amount of tension in the vertical member.

I am reviewing shop drawings for glulam scissors trusses for a cabin.  The manufacturer has bracing at the peak of the bottom chord.  Does anyone know if this is necessary?
