Suspension Bridge:
The Akashi Kaikyo Bridge
Location of the Bridge
The Akashi Kaikyo Bridge, or ‘Pearl Bridge’, is built across the Akashi Strait in west-central Japan. This massive structure connects the city of Kōbe- situated on the main island of Honshu- to Iwaya on Awaji Island. The project began in May, 1988, and was opened to the public in April, 1998- almost a decade following the beginning of construction.
Size and Mass
This bridge is approximately 3,911 metres in total length, with a width of 1,991 m (six-lane roadway) and is 282.8 m in height. The total mass- including both the concrete and steel components- of the Pearl Bridge is estimated at 1.5 million tonnes.
Construction Materials
The Akashi Kaikyo Bridge itself consists mainly of steel, however, to prevent the sway or collapse of the bridge from the ‘fast swirling tidal currents’ of the Akashi Strait they built supporting foundations of concrete. These cylinders of concrete are 70m in height and have a diameter of 80m, each reinforcing the stability of one of the two supporting towers of the bridge.
Similarly, coun...
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). The total Building time of the bridge was 48 months/ 4
“It was designed with a twenty-two foot roadway and one five-foot sidewalk” (Silver). The silver bridge is a very long bridge. “An eye-bar is a long steel plate having large circular ends with an "eye" or hole through which a pin is used to connect to other eyebars (to make a chain) or to other parts of the bridge.” according to Richard Fields. The whole bridge was built using the eye-bar suspension.
Bering Land Bridge- during it’s time of existence the bridge was a major factor in migration from Asia to North America; made travel easier because it was on land instead of having to travel by boat
It became a link between Fort Erie, Canada and Buffalo, New York. The bridge is over one mile long, 5,800 feet, and holds three lanes of traffic. The center lane may go north or south depending on the volume of traffic. In 1934, the Great Depression caused a change.
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
The Jericho Covered Bridge in Kingsville, Maryland was built in 1865 and restored in 1982. The bridge is 100 feet long and cased in cedar planks and timber beams. Legend has it that after the Civil War many lynchings occurred on the bridge. Passersby were supposedly captured on the bridge and hung from the upper rafters. The bridge is very close to my house and I have driven over it several times. The storyteller, age 19, also lives a couple minutes away from the bridge. He has lived in Kingsville, Maryland his entire life. He recalled a dramatic story he had heard from his older brother involving the haunted bridge.
In the DAB Memorial Bridge photo, I believe the artist is trying to show us a past scene.
Since humans are mortal, the sensation of pain is integral to the human condition. On one hand, pain alerts the body of a danger that is threatening its overall well-being; however, pain can be used as a means of torture to break the psyche or willpower of someone. As Lancelot races to save his queen from the evil Méléagant, he encounters the Sword Bridge. This Bridge is notorious for its slender construction, making it impossible for one
In the minds of many, legendary director Alfred Hitchcock’s infamous shower scene in the 1960 classic Psycho brought the phrase “point of view” into the language of the general public. What most do not realize is that those in the many spectrums of entertainment have been taking full advantage of the benefits brought on by an audience being dealt a limited field of vision for hundreds, if not thousands, of years. Prior to the advent of film and theater, the best place to find this method in use was literature. The origin of the point of view in literature can be traced back to the earliest forms of literature, where much of what was dictated and recorded was recounted from life experiences. It is of no surprise to most that the idea of point of view stayed, and evolved into many subsections, thanks in full to the fact that every story has a point of view. In the 19th century, point of view hit a creative peak, with the wildly inventive writers of the period finding new avenues to pursue with their works. Stories from that time period authored by individuals such as Edgar Allen Poe and Ambrose Bierce are still read today. What allows Poe’s “The Cask of Amontillado” and Bierce’s “Occurrence of Owl Creek Bridge” to be taught as shining examples of wonderful literature are not expert characterizations, moody settings, or heart-wrenching themes as one may expect after studying their other works. Instead, it is the point of view methods that both authors employ that make their works so revered.
People who thinks of Thornton Wilder primarily in terms of his classic novella “Our Town,” The Bridge of San Luis Rey will seem like quite a switch. For one thing, he has switched countries; instead of middle America, he deals here with Peru. He has switched eras, moving from the twentieth century back to the eighteenth. He has also dealt with a much broader society than he did in “Our Town,” representing the lower classes and the aristocracy with equal ease. But despite these differences, his theme is much the same; life is short, our expectations can be snuffed out with the snap of a finger, and in the end all that remains of us is those we have loved.
This all iron design made the bridge a lot heavier than it was designed for, which added more stress to the truss. This fact, by itself, wouldn’t cause any alarm. However, the bridge itself, was very poorly constructed. The members of the bridge were all different sizes, and they were not connected together properly. Due to the poor construction and eleven years of use, members of the bridge had started to bend due to the stress. Despite bridge engineers inspecting the bridge for eleven years, no one noticed these faults with the bridge. However, the ultimate cause of this collapse, was so tiny, only one of the investigators, after the collapse, noticed it. A tiny air hole was left during the construction of the bridge, “and grew with repeated stress over eleven years” (Escher, 2009). This hole would develop in a crack, due to the changing temperatures and the trains crossing it for over eleven years. This would weaken the overall strength of the bridge. The cold winter air and the weight of the train would ultimately prove to be too much, and the whole bridge came crashing
A View from the Bridge. 'Justice is very important here' is spoken by Alfieri in his opening speech. Alfieri is a lawyer representing the official legal system of America. He also acts as a narrator, commentator who is almost like a bystander watching the events but remains powerless to have any impact on them. This is very similar to the chorus, featured in tragedies from ancient Greek playwright, who are a group of on lookers watching and commenting on events but are unable to act upon any of the incidents.
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
Eddie Carbone is an American-Sicilian man working in Brooklyn. He works as a longshoreman: carrying crates and goods from the ships. He is quite a large man. His job requires him to be strong and a good worker. In other words he is very masculine. He is an ordinary man. He lives with his wife and niece, whom he treats like a daughter, and like all good men should do, he works every day to provide them with enough money to survive on. Eddie is a man’s man. He lives within a close-knit community of Sicilians and is a well respected member of society. Eddie sees himself as a prime example of how a man should act and look.
en designing for the public, architects and engineers must take into consideration the economic, environmental and social impacts of their design. The three categories; people, planet and profit are the fundamental principles of sustainable architecture. Architecture firm Cox Architecture joined an alliance with the architecture firm Architects 61 and engineering firm Arup to perfectly address the three categories of responsible design while also managing to create an entirely new category of bridge.The Helix, is the first of its kind. Located in the heart of Singapore's Mariana Bay, it acts as a cultural figurehead symbolizing the re-urbanization of Singapore's cultural centres. The Helix geometry is inspired by the unique and universally known shape of DNA. The purpose of the pedestrian bridge is to literally and figuratively connect the cultures of the region and provide a common ground which all could appreciate. The design was intended to be unique to the region and has been quickly recognized as a modern architectural-engineering masterpiece. This report will discuss the unique traits of the design that make the bridge architecturally and environmentally innovative. METHOD One of the main purposes of the bridge was to achieve a higher standard in sustainable bridge design. This was appropriately addressed by the efficient selection of materials and geometry. The entire structural system of the design consists of only stainless steel. A stainless steel skeleton was made economically possible due to the maximization of material function. The bridge behaves like two opposing springs, in which the outer helix transports the load to the base supports and the inner helix supports the deck. As each spiral has a...
