I-35w Bridge Research Paper

The city made notifications not initially planned out and ultimately adding more dead load of the bridge which led to the collapse under too much load the bridge was intended to take. They also added railings to the bridge that did not meet current safety standards in 1998. By replacing them, it added more load to the bridge. During their last renovation of the bridge before the collapse, more concrete was going to be added. They chose to use mixing truck to pour concrete, but Minnesota specifications said that pouring of concrete was to be done on site and mixing trucks could not be used on state bridges. The company's actions to place trucks all over the site to pour their concrete while specifications said that concrete was to be mixed on site without trucks, shows how the actions taken by the company was not morally right in considering state regulations. Bridge construction inspectors determined that the concrete specifications meet required standards and consequently they determined that it was okay to place the materials on the bridge for the

The first completed steel bridge was the Eads Bridge, in St. Louis Missouri. Steel was a very new material and was just starting to become commercially available. Steel was a smart choice to use because it is extremely hard and resists rusting. The Eads Bridge was the longest arch bridge in the world, of 510 feet long. St. Louis became a very important city in the midwest and had to really compete with Chicago during the Civil War. After the Civil War, St. Louis started growing in all directions. “.... the city of St. Louis wanted to reestablish its prewar dominance as the economic powerhouse of the midwest” (Ostrow 75). The main reason to build the Eads Bridge was to connect settlers from the East to the lands of the West. At the time there

In the small town of Waco, Texas who would have thought it was once well known for the structure of a bridge, the Waco Suspension Bridge to be exact. Up until 1870, the Brazos River was just a simple river that had no special meaning to it. The land around it was empty, occasionally you would find cattlemen pushing their cattle across stream, but that was only because you could not find one bridge that spanned the eight hundred miles of river flowing through Central Texas. This caused a serious transportation issue for merchants and travelers. It became clear that a better means of crossing the river was necessary.

In Mary Lawson’s The Other Side Of the Bridge, the proginist, Arthur Dunn faces many problems and obstacles throughout the novel, Arthur eventually overcomes his negative emotions and obstacles and comes to peace with them. Arthur overcomes his resentment and emotions towards Jake and overcomes his negative feelings towards Laura and the farm.

The article “Just a Half a Mile from the Mississippi Bridge”: The Mississippi River Valley Origins of Rock and Roll” was written by Dr. Michael Allen Ph.D. who is a history professor of the School of Arts and Sciences, at the University of Washington, Tacoma. The article is part of a work that Allen is currently working on titled, “Mississippi River Valley: The Course of American Civilization”, which discusses the significance and relevance of the Mississippi River area in American history. Because Allen is writing from the geographic distance of the Northwest, he may have a more objective viewpoint of historical events than someone who is living inside Southern culture. The article was written in 2015 for the Southern Quarterly, which is a

In the middle of nowhere, in that vast expanse of trees, lies The Bridge. Nobody knows it as any other name. It stretches across the Dead River, just sitting there waiting for someone new to find it. At one time it was driven over constantly, a way of travel for the inhabitants who are crazy enough to live out there. But now it is just there, a giant chunk of metal, rusting away into nothing. Occasionally it is used for things like fishing, or as a

In the midst of corruption sits a Great Bridge towering over the landscape as millions of people commute over it, clueless of how deep the crime beneath it runs. In the midst of immigrants sits a bridge that connects one economic powerhouse to another with the ideas and dreams of a German-born immigrant that never got to see his dream completed. In the midst of the mighty East River stands the East River Bridge as a towering monument of mans' ability to make even nature bend toward its iron-like will. In the midst of all this stands the Brooklyn Bridge in all of its glory as the pinnacle of industrial and engineering mastery of that time period and as a testament to the lives of the people that lived through a time of intense corruption, new

In 1919, a study was begun to see if it would be possible to build a bridge across the Golden Gate. Michael O’Shaughnessy was the San Francisco city engineer. He was in charge of the rebuilding of the city after the devastating 1906 earthquake that destroyed much of the city. O’Shaughnessy knew the need for the city to have bridges. Most said it could not be done and others said it could be done but “it would cost about $100 million to build it” (Barter 23). O’Shaughnessy and Strauss, both wanting the same thing, got together. After the two consulted, they figured the only way to bridge the channel was to use a suspension bridge.

Humans have tamed steel, stone, lumber, and even living vegetation, all in effort to reach the people, places, and things that we desire. Although the concept of bridges is as simple as a tree falling across a creek, bridge design and construction requires very serious ingenuity. Artists, engineers, and architects pour vast resources into bridge construction so that they can reshape our daily environment for the better. When building bridges you’ll need help from BATS which are the key structural components of bridge construction such as beams, arches , trusses, and suspensions. Various combinations of these four technologies make it possible for numerous bridge designs, ranging from some bridges as simple as beam bridges, arch bridges,

About eighty years ago, engineers were able to build a bridge on time and within budget with no problem; today, most of the projects take extra time and money to finish. What exactly happened between now and eighty years ago that caused such a drastic shift? It is clearly not the engineers nor the technology; in fact, those have only improved over time. Today, engineers are faced with much more than designing and building the infrastructure, as they were before. They compete with politicians for funds, fight for the safety of workers, and protect our environment by adhering to the numerous laws and acts set forth by the government. In the future, we can only expect more costs, longer time periods for projects, and an increase in costs and

Four months prior to the collapse, a similar design of bridge, also designed by Freeman Fox & Partners, collapsed in Milford Haven, Wales, killing four workers. Understandably, there was a lot of industrial unrest on the construction site of the Westgate Bridge, although workers had been assured by Freeman Fox & Partners that the design of the Westgate was perfectly safe, but was not supported by any relevant or sufficient calculations.

The Tacoma Narrows Bridge is perhaps the most notorious failure in the world of engineering. It collapsed on November 7, 1940 just months after its opening on July 1, 1940. It was designed by Leon Moisseiff and at its time it was the third largest suspension bridge in the world with a center span of over half a mile long. The bridge was very narrow and sleek giving it a look of grace, but this design made it very flexible in the wind. Nicknamed the "Galloping Gertie," because of its undulating behavior, the Tacoma Narrows Bridge drew the attention of motorists seeking a cheap thrill. Drivers felt that they were driving on a roller coaster, as they would disappear from sight in the trough of

The bridge we have created is ethical in the sense that it has a dependable purpose relative to its location, and its uses. By implementing a floating bridge, in a non-linear terrain in the city of Champong Chnnang it allows for effective, and efficient commute between two villages. This idea allows for the saving of time and money, by not implementing a less efficient method of transportation and trade between the two villages. THIS ISN’T GOOD ENOUGH, LET EDWARD ADD SHIT TO THIS TOO.

(far more than expected). The bridge flattened, but was not stressed, engineers say, possibly due to the fact

Because of advancements in today’s technology in construction field, many types of bridges are being constructed depending on the requirement and their suitability for the situations.
