What is K truss bridge?
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. The K truss, probably because of its complexity, did not became very popular in the United States.

Where are K truss bridges used?
Alaska is the youngest state to implement the usage of K-trusses, as five bridges were built along the two main highways (Parks and Richardson) with the longest being a three-span 1300-foot bridge near Nenana (the main span being 500 feet). Each of the five bridges were built between 1966 and 68 and are still in use.
When was the K truss bridge created?
The celebrated Quebec Bridge over the St. Lawrence River in 1917 first demonstrated the value and possibilities of this design. The K form derived from the way engineers subdivided the panels, a proceedure that afforded more strength and economy as it also increased the length of the structure.
Who created the K truss bridge?
The K-Truss truss configuration was invented by Phelps Johnson, president of the Dominion Bridge Company of Montreal, Quebec, Canada, as part of the design effort for the second (existing) Quebec Bridge. Phelps was born in 1849 in the United States and worked for the Wrought Iron Bridge Company for a time.

What is truss and its types?
Simple truss – indicates a single triangular truss. These trusses are most often used as the roof trusses. Planar truss – as the name implies it is a two dimensional truss. If all the members and the nodes are in a planar surface, then this truss is a planar truss.
What are the main components of a truss bridge?
Structurally, Arete Structures truss bridges contains five fundamental elements:
- Foundation/abutments and piers (for multi-span)
- Truss.
- Floor beams and outriggers that connect and support the two trusses.
- Stringers sit on top of the floor beams and support the decking.
- Decking.

What three factors determine the strength of a truss bridge?
distance between truss joints, the smaller the chord section required. Roman Arch Bridge To turn the arch into a truss, all that is required is to provide a tie between the two buttresses to stop them from being pushed apart by the arch. The arch, beam, tie combinations is self-supporting – we call this structure a truss. 10
