What is K truss bridge?
: a building truss in which the vertical member and two oblique members in each panel form a K.
What are the 5 types of truss bridges?
Different Types of Truss Bridges
- Pratt. The Pratt truss bridge utilizes diagonal and vertical beams.
- Howe. The Howe truss bridge is similar to the Pratt design with only a few differences.
- K Truss. The K truss bridge literally makes a backward ‘K” shape along the structure of the bridge.
- Bailey.
- Warren.
- Bowstring.
What are K trusses used for?
The idea of the K truss is to break up the vertical members into smaller sections. This is because the vertical members are in compression. The shorter a member is, the more in can resist buckling from compression.
What type of arch bridge is a type of truss?
Bowstring (Parabolic) Bowstring (Parabolic): This form of truss typically has a curved top chord and is sometimes called an “arch-truss” as well. Most commonly used in the 1870s as an early metal truss form.

Is it cheaper to build or buy trusses?
Today, over 80% of new homes are built with trusses, rather than rafters. The main reason for this is cost. In raw material alone, trusses are 40% to 60% cheaper than making a roof using rafter or “stick” construction.
Which is better rafters or trusses?
Once in place, rafters use up more wood, so they weigh more, but trusses are stronger because they are more efficient and have the capacity to produce maximum strength using fewer materials in the end.
