This project will discuss about some basic structure analysis of prestressed concrete bridge and design a newly footbridge according the structure design manual for highway department.
First, there is several type of the footbridge. We need to compare all form of footbridge and pick the best one to design.
Second, we should choose the suitable place or area to start the construction.
Third, at the same time, we could find the design code and the legal requirement for footbridge design.
Then, we can have show some preliminary drawing (footbridge detail) according the area.
Finally, we can calculate the simple design load (Dead Load, Wind Load, Live Load) base on the preliminary drawing.
A beam bridge consists of a horizontal beam that is supported at each end by piers.
When a load pushes down on the beam, the beam's top edge is pushed together (compression) and the bottom edge is stretched (tension).
Single span beam bridges rarely span more than 100 m to cross great distances.
The beam bridge is general used because of the bridge's simple design and construction. And the simple support beam bridge is the most economical form of the bridge.
Trusses are formed of straight members in a tria...

...hen the cables have placed, the supporting parts of the bridge are finished.
In this part of the report, we have to found all type of the footbridge (e.g. Beam Bridge, truss bridge). We also compare the advantage and disadvantage of the footbridge like cost of the construction, material and appearance).
Then we found the suitable place to plan and design the bridge. We have drawn the preliminary drawing for the footbridge detail such as stairway and ramp.
Finally according the size of the footbridge, we have some preliminary calculate (dead load and live load).
For the next part of the report, we need to have some detail calculation for the bridge. For example, the wind load, the prestressed concrete design, steel design, column and foundation design. With this detail calculation that will make sure the place or location is suitable for the footbridge construction.

- 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....

- ... II. HISTORY The first time that a bridge was considered to cross the Yarra River was as early as 1957 to replace the Williamstown ferry service. Between then and 1961, there was lots of discussion, up until the Lower Yarra Crossing Company was founded. Discussions with the government about a new bridge across the Yarra River were held, but not much was agreed upon, until 1965, the Lower Yarra Crossing Company went bankrupt, and thus emerged the Lower Yarra Crossing Authority, whom in 1967 entered into an agreement with Melbourne based Maunsell & Partners, as well as London based Freeman Fox & Partners to be joint consulting engineers....

- 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 what nature gives him....

- Tacoma Narrows Bridge One of the most influential engineering discoveries in the past century was the ill-fated Tacoma Narrows Bridge. “Galloping Gertie” as she was known to local residents, the massive Washington state suspension bridge shook, rattled and rolled its way into the history books. Legendary in its time, the Tacoma Narrows Bridge held many records and drew tourists from around the world in its short life. However, the famous bridge is not known for its creative engineering or speedy construction, unfortunately the bridge was destined to fail.... [tags: Architecture Engineering History Bridges Essays]

- In the early 1900's, settlers of the San Francisco Bay Area considered the San Francisco-Oakland Bay Bridge, which spans over eight miles long and 500 feet above the water at its highest point, an impossible feat. However, with only a few complications, the bridge was completed by November, 1936. The San Francisco-Oakland Bay Bridge consists of two bridge types. The east section is a cantilever bridge, and the west, a suspension bridge. The 1.78 mile western span of the bridge between San Francisco and Yerba Buena Island presented the first obstacle....

- The Hoover Dam is a modern marvel and a testament to American ingenuity. At over six million six hundred thousand tons and jetting seven hundred sixty feet from the canyon floor, six hundred sixty feet across the bottom and, one thousand two hundred forty four feet across the top, the structure is awe inspiring even to a modern audience. Three quarters of a century since its completion it still stands as a symbol of one of the greatest construction projects of the ages. The need for a dam to block the Colorado River was not a new idea when construction began in 1931, but had been mulled around since the dawn of the century.... [tags: dam, power, project]

- It is common knowledge that steel structures revolutionized building design during the early 20th century. It is less well known, however, the impact concrete has had on building design - particularly in skyscrapers. Concrete is an old building material, dating well back into prehistoric times. Yet its application for building tall structures was only truly begun to realized in the early 20th century. Concrete systems in skyscrapers are a unique brand of structure. They incorporate many different elements, and have a variety of different requirements.... [tags: ancient romans, building design]

- The usage of concrete was explored by the Early Christian and Roman architects but fell out of use throughout the Middle Ages and Renaissance period. The material was only fully explored again in the later half of the 19th century but only for mundane purposes where the material was cheap, easy to work with, and versatile, but most importantly it’s fireproof characteristic. In 1870, the idea of reinforcing the concrete was born; steel rods were to be inserted to increase its strength. Taking this principle, Ernest Ransome (America) and Francois Hennebique (France) both developed frame systems.... [tags: Ernst Ransome, architecture, concrete]

- Concrete poetry presents its readers with a unique and often confounding situation. In addition to using language or parts of language in non-traditional ways, concrete poetry also uses elements that are more commonly associated with visual art. However, concrete poetry is not visual art. It is still concerned, primarily, with the use of language, generally to communicate some meaning to the reader in a way that is undeniably linguistic in nature. Concrete poetry is therefore an especially unique genre that draws upon and incorporates many different concepts from a variety of disciplines in order to fill in the gaps left when traditional grammar and syntax are eschewed....

- PROPERTIES OF HIGHLIME FLY ASH CONCRETE ABSTRACT Fly ash is a waste product from coal based thermal power stations. About seven million tons of fly ash is being produced annually from these thermal power stations in Turkey. Concerted efforts are needed to make the material used to a great extent.
