Scissors trusses are used almost entirely in building construction to support a ...
The roof beams are supported by steeply angled scissor trusses that form an "X" shape with a narrow top span and a broader bottom span, tied by a bottom truss to prevent collapse. Additional support is given by a truss that cuts across the "X", below the crossing point but above the bottom truss.
