Balls Bridge and Truss Bridges: A Brief Historical Overview Nathan Holth Foreword: I composed this brief and informal overview of truss bridges and Balls Bridge to put this beautiful historic bridge 's history and significance into context. A version of this document with full-color photos is available on my website 's Balls Bridge Page located at www.historicbridges.org/ontario/balls/index.htm which also has more information and photos. The general truss bridge information in this document was

why we use bridges on a daily bases. Such as for roadway use, waterway, railway etc. Many people don’t think about the reasons behind a simple truss bridge because it takes no effort to drive over one, and because they are there for your use. If you don’t consider truss bridges you most likely don’t think of the physics, the timing, effort, and hard work to make the truss bridge. On my essay on Truss bridges I will over run the history of a truss bridge, the process, types of truss bridges, roadbed

The “Pratt” Truss bridge invented by Thomas and Caleb Pratt in the 1840’s is a unique bridge that combines lightweight and strong structural support providing a very supportive lightweight wide bridge. The bridge uses both diagonal and vertical beams forming a triangular structure. The diagonal and vertical shape of the beams are very strong and light because the triangular shape that the beams make are ridged, utilizing a minimal amount of timbers. The material used in these bridges is also a big

I decided to make a warren truss bridge for this project (Wikipedia, 2015). This type of bridge uses equilateral triangles to help bare tension or compression forces that the bridge may undergo (Mudaliar, 2015). I picked this design because it is a popular bridge design and it will have a smaller mass then some other bridge designs. This design has the potential to be very efficient in the amount of weight it can hold because of it being lighter than other designs. The one problem you have to solve

The truss bridge reflected many of the qualities of America 's industrial society by the early twentieth century: steel-made, mass manufactured, practical and unglamorous, sturdy and dependable, cost-competitive, and highly versatile. Such structures were, wrote David Plowden in his splendid Bridges: The Spans of North America, "appropriate icons to our industrialization." For the developing state of Oklahoma, steel trusses held symbolic value too, for they provided tangible proof to a wider world

Truss Bridges are a common style of bridges used in the United States and all around the world. Some characteristics of truss bridge are joining a variety of relatively small structural members in a series of interconnected triangles. The vertical columns might work on tension and compression, but it depends on the dynamic loads that are applied and the complexity of the bridge. Many of the Howe truss were usually located in the North West part of the U.S because of the supplies available to them

are bridges used for? They are used for the world to transport goods in railways and to support vehicles across landscapes and water. The Truss bridges have many different types which all triangular figures are put to use in the design of each bridge. Most bridges were made with these designs across the world around the 19th century, but today there are only a few left in America and most have been rebuilt. The most common types of Truss bridges are: Warren Truss, Pratt Truss, and Howe Truss. The

brainstorming, we have considered numerous bridge designs that will suit the spaghetti bridge experiment that can withstand the load. We have decided to focus on a truss bridge type with suggestions of either Howe, Pratt or Warren truss bridges. Upon research of each type of trusses we have decided to build a Pratt truss bridge based on the simplistic design and the ability of the group members to construct the bridge with spaghetti. The Pratt truss bridge is an ideal bridge for its structural mechanics. The

common types are the beam bridges, arch bridges, suspension bridges, cantilever bridges, cable-style, and the kind I am going to research is truss bridge. Zhaozhou Bridge is the oldest bridge; it is in china. The first welded bridge was designed by polish engineer Stefan Bryla. The longest suspension bridge in the world (from 2010) is the Akashi Kaikyo bridge in Kobe Japan. Allan truss is based on the Howe truss. The first one was finished on 13 August 1894. Bailey truss was made for the military
