Cantilever Through Truss Bridge Essay

1360 Words3 Pages

A Cantilever Through Truss Bridge is a bridge that is formed by two or more cantilevers placed back to back. First of all, a bridge is a structure built to span across to connect two physical features, such as; land, valley, body of water, railroad. A span is the horizontal sector between the two supporting structures of the bridge. A cantilever is a structure that projects from a supporting column. The cantilever is counterbalanced and/or supported at one end only. The cantilevers are supported in the center of the bridge at the piers. The Cantilever Through Truss Bridge contains a suspended span in between the set of cantilevers. The suspended span in the center is a truss, more specifically, it is a through truss so the structure is above the travel surface. The “Through Truss” section …show more content…

A suspension is where the deck of the bridge is held below by vertical suspenders. These bridges must contain three main parts to it. The parts of the suspension bridges are the towers to hold the cables that suspend the bridge to carry its weight, the cable itself, and deck structure. Each suspension bridge is specifically designed for each unique bridge taking on account of a couple of affecting factors. Some of those factors are the geology of the area where the bridge is hoped to be built and if it may be susceptible to natural disasters, such as earthquakes. The image in the figure below demonstrates a tremendously built bridge in San Francisco, California that is a superb example of this type of bridge.

Figure 8. Suspension Bridge
This figure above displays a wonderful model for the suspension bridge detailed above. Suspension bridges have cables that are connected to two tall towers. The Golden Gate Bridge has two main towers that support the two main cables. These cables receive the tension forces of the bridge. The Golden Gate bridge in San Francisco is about 2,737 meters long.

    71,300 tons of structural steel, 931,000 tons of concrete 42,000 miles of cable wire weighting 11,840 tons, 4,851,700 steel rivets and 1,016,600 steel bolts were all used in the building of the Mackinac Bridge. 1,024,500 tons in total weight is what all this ends up weighting to (Mackinac Bridge 3) (Mackinac Bridge 8). The Main Mackinac Bridge towers reach 554 ft above water and 210 ft beneath the surface to bedrock (Mackinac Bridge 8). To contain temperature changes, high winds and changes of weight on the Mackinac bridge, the deck can move left or right as much as 35 ft at center span. (Mackinac Bridge 9).

    Since the invention of the automobile, there have been many great innovations within the industry. The suspension of the automobile serves as a good example of one of those innovations. Could you imagine riding around in your brand new Nissan Skyline GT-R, with the same suspension methods used to stabilize old horse and carriage buggies centuries ago? That would not serve its purpose very well. Due to the demands of society, vehicle stabilization became a priority to increase safety. Throughout the years, there have been different variations of vehicle suspension systems. For example, we have adaptive air, solid axle, and dead axle suspensions. Without the advancements made in the way we travel and transport goods, civilization could not prosper the way it has.

    The area of where the bridge was to cross the Ohio River was said to be one of the hardest places to build but came with some advantages. The section of the river had a solid rock base for the supporting pier to be built on. Since the engineers knew they could build a pier that would not settle they decided on a continuous bridge design. This design type distributes the weight so the steel trusses could be smaller and riveted together. This alone saved an estimates twenty percent of steel that was originally thought to be need to make the bridge cutting down the cost. The two continuous trusses span a collective 1,550 feet across the water. With addition of the north and south approach viaducts, for trains to go under the bridge, the superstructure’s total length is 3,463 feet. The bridge was made to hold two sets of tracks making the width 38 feet and 9 inches. The design called for 27,000 cubic yards of concrete and 13,200 tons of steel with some members being four foot square beams that span a distance of seventy feet. The design was the first step in a long process that would take several years to

    According to Suspension bridges: Concepts and various innovative techniques of structural evaluation, “During the past 200 years, suspension bridges have been at the forefront in all aspects of structural engineering” (“Suspension”). This statement shows that suspension bridges have been used for over 200 years, and that people are still using them today because they are structurally better bridges. This paper shows four arguments on the advantages of suspension bridges, and why you should use one when building a bridge. When deciding on building a suspension bridge, it has many advantages such as; its lightness, ability to span over a long distance, easy construction, cost effective, easy to maintain, less risk

  • Research Paper On The Golden Gate Bridge

    665 Words  | 2 Pages

    The bridge’s construction was started on Jan. 5, 1933, after, “Experts at the time determined that a bridge was needed in San Francisco, since it was the largest American city still using mostly ferry boats.” (Shiff, 2017.) Prior to the bridge’s construction, ferries were used to move cars across the Golden Gate Strait. The bridge was seen an engineering feat that would have been impossible, until improved construction technology made building the bridge a challenging but possible task. A bridge across the Golden Gate Strait would need to withstand high winds, tides from the bay, heavy fog, and possible seismic activity from the San Andreas fault less than 8 miles away. The bridge was designed by engineer Joseph B. Strauss and was completed on April 19, 1937. The bridge used more than one million tons of concrete to create the two main towers, and the bridge is also supported by approximately 80,000 miles of suspension cables. The Golden Gate Bridge was one of the first bridges of this magnitude and size to be built. The grand bridge connected these two sides of California, and lead to major changes for economics, transposition, and the

    In her essay,”Importance of the Golden Gate Bridge,” Stephanie Stiavetti suggest that “It maintained this point of pride for nearly 25 years until the Verrazano- Narrows Bridge was built in New York in 1964. Today, this historic San Francisco landmark holds its place as the second largest suspension bridge in the country, behind Verrazano Narrows.” Back then, experts thought that it would be impossible to build a bridge across the tides and currents in that area because strong currents and tides would make construction extremely difficult and dangerous. The water is over 500 feet deep in the center of the channel, and along with the area's strong winds and thick fog, the idea of building a bridge there seemed nearly impossible. Despite all of the problems of building a bridge across the Golden Gate, Joseph Strauss was named as lead engineer for the project. Construction began January 5, 1933, and in the end cost more than $35 million to

  • Suspension Systems

    There are many different types of suspension systems that are used in cars today, and some that were discontinued due to their uselessness. One example of an older suspension system is called the swing axle suspension. This is a very old type, used in many sports cars in the 50’s, but had disappeared for about 2 decades. This was due to the weakness of the system. The handling was awful, as the camber angle can be noticeably changed by a simple bouncing motion, and the change of the static weight and body roll as the car took a corner. The only advantage to this type of system was that it could provide independent shock absorption. (Wan)
