Where was the first Warren truss bridge built?
The first suspension bridge to utilize a Warren truss in its design was the Manhattan Bridge in New York City.
What is good about 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).
Why is it called a Warren truss?
In structural engineering, a Warren truss or equilateral truss is a type of truss employing a weight-saving design based upon equilateral triangles. It is named after the British engineer James Warren, who patented it in 1846.
Who designed the Warren truss?
James Warren
Figure 2. Warren Truss with verticals to support top chord and deck structure. Neither of these truss styles are what James Warren and Willoughby Monzani patented in 1848 in England.
What is a Warren Truss with verticals?
Warren truss contains a series of isosceles triangles or equilateral triangles. To increase the span length of the truss bridge, verticals are added for Warren Truss. Pratt truss is characterized by having its diagonal members (except the end diagonals) slanted down towards the middle of the bridge span.
How does a Warren Truss distribute forces?
The Warren Truss uses equilateral triangles to spread out the loads on the bridge. This is opposed to the Neville Truss which used isosceles triangles. The equilateral triangles minimize the forces to only compression and tension.
Why is Warren truss strongest?
I think the warren-truss design will be the strongest because it is the simplest design and spreads the weight of the load evenly over the bridge. Popsicle sticks and glue were used to build 3 different bridge designs: Pratt truss, Warren truss, and K truss. 5 identical models of each design were built.
When was the Warren truss first used?
Patented in 1846 by British engineers James Warren and Willoughby Monzoni, the Warren truss and its variants constitute a commonly built metal truss bridge type of the nineteenth and early twentieth centuries.
Who invented the first truss bridge?
In 1840 William Howe patented the Howe truss, another truss that enjoyed widespread popularity. Howe based his design on the limited stress analysis information available at that time, the first designer to do so since previous trusses were unadaptable to analysis (Edwards 1976:156-157).
