Scissor Truss

The Scissor Truss is a striking, yet more complicated timber truss design. It is structurally sound with raised bottom chords that give an interior space more vertical height. Usually the bottom chord pitch is about half of the top chord pitch. An 8/12 top chorded scissor truss might have a 4/12 bottom chord. Scissor trusses need to be designed with big enough members so they don't deflect (spring out) too much. VTW likes the deflection to be limited to L/360 at a maximum, or 1/2″ or less under full load.
