In the past, it is not much pedestrian traffic along the street because of the lower population. However, due to the population increasing in 1960-70s.The government considerate that the number of pedestrian traffic such as footbridge is so important, so the government have to increase the total number of all pedestrian traffic like footbridge. With the time changed, the safety and technical of bridge structure form has also changed and improved. Nowadays, almost footbridge in Hong Kong is made by concrete including prestressed concrete bridge.
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.

The San Francisco-Oakland Bay Bridge Essay

- 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....   [tags: Transportation, bridge]

The Use of Reinforced Concrete in Modernism Essay

- 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]

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....   [tags: Concrete Poetry Analysis]
