Description

A scissored double Howe truss is a type of truss with diagonal members sloping to the center of the truss and sloped bottom chords. The double Howe truss is made up of five vertical posts and four diagonal webs (two on each side). The vertical posts provide support for the weight of the truss, while the diagonal webs resist the forces of compression and tension. They are also used in buildings that need to have a high ceiling height. The scissor-like shape of the diagonal members allows the truss to support a large amount of weight.
