What type of truss features a design with both top and bottom chords along with web members?

The W-Type (Fink) Truss is characterized by its design that includes both top and bottom chords, along with internal web members that connect these chords. This truss design is widely used in building construction because it efficiently supports loads over large spans while minimizing the amount of material needed. The combination of top and bottom chords creates a triangular pattern with the web members, which enhances the structural integrity and distributes forces effectively throughout the truss. This makes it ideal for roofs and other structures where strength and weight considerations are crucial.

In contrast, other truss designs have different configurations and applications. For example, a simply supported truss does not have specific characteristics regarding the inclusion of web members or the arrangement of chords, while the scissors truss typically features a shape that creates a vaulted ceiling with intersecting chords but not necessarily the configuration described in the question. The king post truss is simpler, usually only including a central vertical member and two top chords, and thus also lacks the complexity of web members found in the W-Type truss.
