What bridges use the Warren truss?
Warren Truss for model bridges I have definitely used the Warren truss design for many balsa and basswood bridges. I have also used for some popsicle stick bridges. In fact, you can get a learning kit using a Warren Truss from my store.
What are the advantages of a Warren truss bridge?
One of the main advantages of a Warren Truss is its ability to spread the load evenly across a number of different members; this is however generally for cases when the structure is undergoing a spanned load (a distributed load).
How strong is a Warren truss bridge?
Of the three bridge designs I tested (warren-truss, pratt-truss, k-truss) the warren-truss held the most weight. I tested each design 5 times and the average for the warren was 43.6 pounds. The k average was 31 pounds and the pratt design was the weakest and averaged 13.6 pounds.
How much weight can a Warren truss bridge hold?
These were a Warren Truss, a Cantilever, an Arch, a Half Through Arch, a Beam and a Gabke Stayed Truss. The bridge type that held the most weight was the warren truss bridge, holding a total of 41 pounds.
Which truss bridge is strongest?
In this experiment we have tested which type of truss bridge is the strongest, yet uses the least amount of material. Two of the most used truss bridges are of the Pratt and Howe design. Through our experiment it was found that the bridge design that minimized the maximum compression force was the Howe Bridge.
Where is the Warren truss bridge?

What is Warren truss used for?
The Warren truss is perhaps the most common truss for both simple and continuous trusses. For smaller spans, no vertical members are used lending the structure a simple look. For longer spans vertical members are added providing extra strength. Warren trusses are typically used in spans of between 50-100m.
Where is Warren truss used?
Warren truss construction has also been used in airframe design and construction, for substantial numbers of aircraft designs. An early use was for the interplane wing struts on some biplanes.
What truss bridge holds the most weight?
arch bridge
The arch bridge can hold the most weight of the three, the deck truss bridge can hold an average amount of weight, and the beam bridge could hold the least amount of weight.
What is the Warren truss bridge design?
The Warren truss bridge design includes an interior railing that is connected to the diagonal span, preventing people from falling off the edge of the bridge. The truss makes use of Newton’s principles of motion, particularly statics, which is a key aspect of the laws.
Do they still make Warren bridges?
Unfortunately, not many Warren bridges are made anymore. I have definitely used the Warren truss design for many balsa and basswood bridges. I have also used for some popsicle stick bridges. In fact, you can get a learning kit using a Warren Truss from my store.
Where did the Warren truss come from?
Warren Truss. James Warren patented a design in 1848 (in England), which many attribute the name “Warren Truss”. His patent was more about the methodology of building rather than a a “design”. Regardless, the Warren Truss has been around a while and has been very popular. Examples of it can be found everywhere in the world.
When was the first truss bridge made?
The first bridge of a truss design was built in the 1840s, by Alfred Neville in France. However, this bridge used an isosceles triangle framework. The Warren truss bridge design was patented in Britain by James Warren and Willoughby Theobald soon after in 1848, with an equilateral triangle framework.
