What Is a Scissor Truss?
A scissor truss is a type of truss in which the lateral beams form a kind of symmetrical shape, like the two shears of a pair of scissors. In general, the term “truss” refers to a structure that holds a roof in place. Residential roof trusses are commonly made of wood with steel accessories, where some truss types are made of steel. Trusses provide the framework for a roof. The original design of a roof truss was a triangle, allowing for the traditional peaked shape of a roof, with the lower part of the roof truss helping to form a ceiling for an interior space. Today, most trusses are thoroughly engineered using computer tools, including in depth simulations. This means trusses are being built in an increasing variety of shapes.
