Which type of truss features two parallel horizontal members connected by diagonal and vertical members?

The parallel chord truss is characterized by its two horizontal members that run parallel to each other, typically referred to as the top and bottom chords. These chords are connected by a series of diagonal and vertical members, which serve to distribute loads and provide structural integrity. This design allows for efficient load-bearing capabilities and a wide span, making parallel chord trusses commonly used in floor systems and roof structures.

In contrast, the pitched chord truss has sloped top chords that create a peaked roof profile. The bowstring truss has a distinct curved top chord shape, resembling a bow, which is ideal for applications that require an arch-like structure. The king post truss is typically a simple truss designed for shorter spans and incorporates a central post connecting the peak of the triangle to the base. The unique characteristics of the parallel chord truss make it suitable for specific construction applications, emphasizing its structural advantages in various settings.
