Burr Truss

At one point in time, there were roughly 400 to 500 covered bridges in the state of Indiana. Beginning in 1835, Henry County contained the first covered bridge in Indiana history. In 1937, Indiana was home to 202 covered bridges; Dearborn County had two. By 1998, there was only one covered bridge in Dearborn County, and it is known as Guilford Covered Bridge (Covered Bridges in Indiana). Guilford Covered Bridge was built in 1879 by A.M. Kennedy and Sons, who had built around fifty covered bridges in Indiana by the 1900s. The bridge was built with a Burr arch truss located in Guilford, Indiana, over Tanners Creek as the entrance into the small town. The bridge was seventeen feet nine inches wide, twelve feet nine inches tall, and one hundred four feet long with a seven foot overhang at both ends. The bridge contained distinctive Kennedy aspects, including the distinguishing portal arch, with scrolls engraved in them, and the cornice blocks. The most uncommon part of the bridge was the floor. Made of wood paving blocks, the feature was unique in covered bridges. The one lane bridge had a shingle…

Edmond Liu My popsicle bridge is based on a truss design, which is a bridge design held up by a connected structure composed of many smaller pieces. In particular, my bridge is a variation of the Queen Post Truss Bridge, which has two central supporting posts to allow for a greater span allowing for larger contact points. (http://pghbridges.com/basics.htm) My design is modified to incorporate two extra posts towards the two contact points where the bridge rests on the desk, to increase the…

This is a simple bridge because the ends of the girders are on top of the pier and abutments. The span of a girder bridge can go up to 1,000 feet. Truss bridges are bridges that are supported by trusses. The trusses are set in a triangular pattern. A truss bridge can have a span of over 1,000. Every truss is a triangle formed by wood or steel. Engineers prefer a girder bridge because it looks better, however it uses more materials. Arch bridges are another common type of bridge. Each span of an…

There are many different types of bridges. More specifically, there are many types of truss bridges. One popular truss bridge is the Golden Gate Bridge, which is located in San Francisco, California. This bridge is a Warren deck truss bridge because of the equal size of the diagonals and to contain both tension and compression (Types of bridges) and it has a Suspension, fixed and approach Spans because of the metal braced ribbed deck arch.(Golden Gate Bridge). Some other important features of…

By Brigid Garrett , Wyatt Mullings, Jesus Sanchez, and Lydia Blaisdell Cable Sensation Russky Bridge, Vladivostok, Russia. What are Cable/Stayed Bridges? A cable/stayed bridge is a bridge that has two towers with cables supporting the bridge itself, as shown above. The towers are called pylon, the crossing area itself is called the roadway. The cables are obviously called cables. The supports underneath on the sides are called abutments, The foundations are located under the ground on the…

Line: During my observation of Three Cranes, lines that appear to be distinguishable would be the horizontal lines as well as the diagonal lines. The horizontal lines are noticeable since the image appears to be in layers, which involve layers of soil, grass, shade, and light. Furthermore, the image presents diagonal lines through the posture, position, and sight of each crane. The crane whose body is closest to the soil represents a wide diagonal line that appears to be increasing from right…

Arch bridge, Truss bridge, Cantilever bridge, Cable-Stayed bridge, Beam bridge and Suspension bridge, All ranging with different designs. All of the different bridge designs are made to withstand a specific amount of weight. A bridge supports weight when the base of the bridge is made out of strong and good material to support the long span. Bridges can hold heavy loads because of the constant pulling and pushing force of each part of the bridge. This form of force is commonly known as…

Part A: Here in Tennessee we are in a valley with lots of lakes and water falls between the mountains. The water falls have swinging bridges going across them and not everyone will walk across because of the fear of it breaking or swinging too much. So my idea is to have the children build a regular bridge with a roof that does not swing and sheds shade to those in wheel chairs can enjoy the water falls and bridge as well. In this activity we will use Lincoln logs to build a two layer bridge…

a. The bridge is in Banff, Alberta within Canada’s first national park (Structure Craft, 2013). It was completed in 2013 by Structure Craft Builders and is one of the longest timber bridges in the world, achieving a span of 80m within its total length of 113m (Structure Craft, 2013). b. Principle Structural System The principle structural system is comprised of drilled piers to support 40m long glulam girders cantilevered (Structure Craft, 2013). The elevation of the bridge displays stepped…
