Case Study: The 130th Street Bridge

Our group chose to research the 130th Street Bridge, built in 1949 and is located in Cook County, Illinois over the Calumet River. The 130th Street Bridge is a polygonal Warren through truss with connections. You can tell it is a Warren truss bridge because it has thick diagonal members and verticals and its form of triangular shapes. This bridge is unique because it is a movable bridge and it is one of the most historic bridges in Chicago, Illinois. It is the largest truss bridge ever to be moved into place after being built off site. This bridge has deck plate girders which make it easier to move and get loads across. The climate of Illinois is temperate which basically means Illinois has winter, spring, summer, and fall, all the 4 seasons. The bridge spreads 400 feet along the Torrence Avenue. The process of building the bridge costs $101 million, which seems like a lot for a bridge, but it is really not once you factor costs for all the materials. The bridge was made to transport the truss 800 feet to its location 4 hours.
Knowing major components can play a key role when you are creating something like a truss bridge, when you are creating a truss bridge it usually consist of 7 different major components which are the Vertical (located a quarter through the middle of the bridge) the Hip vertical (located at the left and right end of the 130th bridge) the Top chord (known as the flat surface that is over the bridge and holds the vertical and hip vertical along with the support of the bottom the chord) the Deck (platform above the bottom chord it also what the cars will drive on) the Diagonal (diagonal lines that are connected to the verticals creating a triangle formation), the Bottom chord (it holds the deck and the top chords, and vertical long with the top chord) and the End post which are the post that go to an angle and connect the top and bottom chord. Each of the components is in specialty to the truss
They have it under the subject civil engineering. Some parts of research include laboratory investigations of soil behavior with modeling of their behavior with strong foundations with dynamic loads dynamic loads and the development of soil. Every structure on earth is founded on soil and or rock. Geotechnical engineering relates to our bridge because our bridge is being built near an area that has soil. Material engineering is the value of our materials. Our materials have been rich in value because we want our materials to be safe and want out bridge to
