Bridge

The Washington State Bridge and Structures office is responsible for managing Washington state’s bridge inventory. There are roughly 7,300 bridges in the state, of which 74% are concrete structures (WSDOT Web). Bridges have an average expected life cycle of 75 years. The average age of existing bridges in Washington State is 45 years old, therefore are over halfway through their expected life-cycle (WSDOT Web). To ensure safety of the public, periodic inspections and repairs must be performed to

The Golden Gate Bridge is “considered to be one of the best and most beautiful examples of bridge design” (Poel and Royakkers 110). Unfortunately, this bridge is also "the US's most popular place to commit suicide" (110). Due to this fact, bridge designers decided that they needed to consider the option of installing some sort of suicide prevention system. Before any decision was made, the ramifications of both implementing a system and not implementing one had to be considered. Deciding whether

$23 million Goodwill Bridge gives a person on foot and bike a crossing over the Brisbane River interfacing the Southbank Parklands to the Brisbane Botanical Gardens. The most unmistakable component of the 470m long engineering composed extension is the 102m double curve arch between the south bank of the waterway and the primary structure amidst the Brisbane River. Foundation tasks are normally planned and built utilizing entrenched points of reference. The Goodwill Bridge is an unordinary bit of

The suspension bridge is a very popular type of bridge all over the world. It’s hard to build but can be built in a lot more places than an arch or beam bridge. Scientists do not know when it was invented. They believe it was near the 15th century. Whom it was invented by is also unknown. A suspension bridge can span distances from 2,000 to 7,000 feet, longer than any other type of bridge in the world. It is a very unique bridge. A suspension bridge is a bridge with the weight of the deck supported

concluded that bridge failures were due to several factors beyond human control that could not have been prevented, it appears that a careful examination of case studies suggest that the failures actually could have been prevented with a more efficient, reliable design. 1) Akesson, B. Understanding Bridge Collapses. London: Taylor & Francis, 2008. Print. The point of this book is to present the most popular cases that involve bridge failures. Every case included careful analysis of the bridge that had

The Golden Gate Bridge Since the dawn of time, man has had an inherent need to get to the other side. Rivers, canyons, and impassable trails have always hindered the migration of man, leaving him the choice to continue no further, or to “build a bridge and get over it.” The earliest bridges were made of simple materials such as stone, or even a fallen log. Regardless of the material, natural bridges allowed man to explore the “other side.” However, man has never been satisfied with

I think a suspension bridge would be the best type of bridge to build from location D. This is because suspension bridges typically can span distances from 2,000 to 7,000 feet long - location D spans a distance of 4,200 feet across an ocean bay where long ships come and go. The other bridges would not be adequate enough to connect Hebron Island with the mainland. For example, an arch bridge cannot be connected numerous times in the ocean without structural support from the ground, and can only span

When: Five years after the Civil War ended, John A. Roebling’s idea of a suspensions bridge came to life. The Brooklyn Bridge’s construction started January 3, 1870. On May 24,1883, the Brooklyn Bridge was opened for the first time Where: In 1870, Manhattan and Brooklyn were two different and separate cities, separated by the East River. It took commuters hours to cross the river each day because the only way to cross the river was to board one of the slow moving ferries. So, John Roebling wanted

This report mainly presents causes and consequences that resulted in the structural failure of the I-35W Mississippi River bridge which was constructed since 1964 and the further implication for me. It was found that the bridge collapsed due to undersized gusset plates, inefficient maintenance project and overloaded equipments. As a result of the abrupt collapse that brought about 13 dead and 145 injurers, the state government carried out a series of effective rescue, forced the designing company

Suspension bridges were important before 1940 and are still important today. Major cities such as San Francisco, and Manhattan both have a suspension bridge. Suspension bridges are,” a bridge having a deck suspended from cables anchored at their extremities and usually raised on towers” (dictionary.com). Due to the fact that suspension bridges are not completely supported throughout the length of the bridge, past bridges were unsafe. For example, the Tacoma Narrows Bridge was a suspension bridge opened
