Bridge

Types of Bridges On the basis o life bridges are classified in to two categories : 1) Temporary Bridges 2) Permanent Bridges Temporary Bridges The bridges which can be constructed as well as maintained at low cost and have short span of useful life are known as low cost or temporary bridges. These bridges are usually made of timber. But they may also be constructed of steel wire, old telegraph posts, hemp rope ,old rails etc. the useful lif of temporary bridges may be taken as 10 years. Necessity

Science Questions Identify and discuss the design elements that you incorporated into your bridge. Design Elements: While building this bridge, the first design element, was the deck design. We took around one horizontal length of vertical popsicle sticks and lined them side by side, and repeated. Later we connected them together with a horizontal popsicle stick. I then took two lines and placed them ontop of eachother to create a flat surface. This way it will carry a lot of weight, and it will

Silver Bridge 4.1 Background The Point Pleasant Bridge or so called the Silver Bridge was designed by the J.E. Greiner Company and built by the Gallia County Ohio River Bridge Company to connect Point Pleasant, West Virginia to Gallipolis, Ohio. It was designed as a two-lane eye-bar suspension type bridge, measuring 2,235 feet in total length, including the approaches. The bridge was the first eye-bar suspension bridge of its type to be constructed in the United States. [26] Figure 4.1: The Bridge

BRIDGES AND THEIR TYPES Highway Bridges Bridges are an essential part of the transport infrastructure. General Information: A bridge is a means by which a road, railway or other service is carried over an obstacle such as a river, valley, and other road or railway line, either with no intermediate support or with only a limited number of supports at convenient locations. Fig: Docklands Light Rail Bridge, London, England. Basic features of bridges: Superstructure `The superstructure of a bridge

Bridges are a connection of one place of the world to another. They link the vast world together. Bridges were used thousands of years ago, especially by the Romans. In the ancient times and present time, several forces are always encountered when building bridges. The forces determine how big or sturdy a bridge will be. There are several types of bridges, such as the girder bridge, arch bridge, truss bridge, and suspension bridge. Bridges have been used for a great amount of time. This allows us

SCENARIO The French government had donated that bridge to help the Haitian people. As I stated before, this kind of bridge must not stay on the terrain for a long time. This time would be different due to the peculiar situation of those villages. The cities of Dondon and San Rafael used the former bridge for many purposes like to take children to school, go to the doctor appointments and day-by-day displacements. The old bridge had fallen three years ago during a tropical storm. Since that

Kaylie Griffin and I chose to build the Clifton Suspension Bridge. The Clifton Suspension Bridge is a suspension bridge located in Bristol, United Kingdom. A suspension bridge is a type of bridge which the deck is supported by cables that hang vertically off larger cables or hangers. Suspension bridges typically have two towers and are anchored to abutments at their ends.The towers help to support much of the weight that crosses the bridge’s deck, such as cars and people. The towers also dissipate

Physics of Bridges The physics behind bridges is more complex than first meets the eye. To assure that a bridge is well-supported many concepts must be understood and used in the correct manner. What is a bridge? A bridge is a complex structure allowing passage across an obstacle: a structure that is built above and across a river, road, or other obstacle to allow people or vehicles to cross it. Bridge forms There are four major forms of bridges: beam, truss, arch, and suspension. A beam

American Bridges Choosing the right type of structure in bridges is one of the main challenges of the civil engineering while building one of them. The structure types can be arch, beam, truss, suspension and cable-stayed. Among this diversity of designs, two important bridges of the United States are the already constructed Mike O'Callaghan-Pat Tillman Memorial Bridge, which is an arch bridge that connects Nevada and Arizona above the Colorado River; and the St. Anthony Parkway Bridge, which is

The “Pratt” Truss bridge invented by Thomas and Caleb Pratt in the 1840’s is a unique bridge that combines lightweight and strong structural support providing a very supportive lightweight wide bridge. The bridge uses both diagonal and vertical beams forming a triangular structure. The diagonal and vertical shape of the beams are very strong and light because the triangular shape that the beams make are ridged, utilizing a minimal amount of timbers. The material used in these bridges is also a big part

Advantages and Disadvantages of a Suspension Bridge: As the name implies, suspension bridges hold the roadway by cables, ropes or chains from two tall towers. These towers support the majority of the weight as compression pushes down on the suspension bridge's deck and then travels up the cables, ropes or chains to transfer compression to the towers (Lamb & Morrissey, 2000). The towers then distribute the compression directly into the earth. The supporting cables, on the other hand, receive the bridge's

The Physics of Bridges The design of the bridge superstructure is based on a set of loading conditions which the component or element must withstand. A bridge engineer must take into account a wide variety of loads which may vary based on the duration of the load (permanent or temporary), the direction of the load (vertical, longitudinal, etc.), and the effect of the load (shear, bending, torsion, etc.). In order to form a consistent basis for design, organizations like AASHTO, American

use to make three bridges of the same common design, the truss design which uses triangular beams because triangles are the strongest shape to use when you build bridges. The materials that I will use to make these 3 bridges are popsicle sticks, Lego bricks, and aluminum foil. My dependent variable how much weight each bridge can endure before the bridge breaks apart. When you add weight tension is created. (tension is a pulling force that occurs at the bottom of a bridge) when tension is applied

Arch bridge is one of the most popular types of bridges, it came into use over 3000 years ago and remained in height of popularity until industrial revolution and invention of advanced materials that make architect to create other modern bridge designs. However, even today arch bridges remain in use, the arches can be built on much larger scales with the help of modern materials. Its curved design is the basic principle of arch bridge, it does not push load forces straight down, but instead they

Our next destination was one I couldn’t wait to go to, the Williamsburg Bridge. I was excited because I love seeing and learning about the architecture of a bridge and also being able to walk over one is so amazing! “Construction on the bridge began in 1896 and opened it on December 19, 1903. When it was completed the Williamsburg Bridge set the record for the longest suspension bridge in the world. It was also the first bridge to use steel instead of masonry towers, which reduced the side of the foundations

Abstract This paper explores the construction aspects of arch bridges, specifically the New River Gorge Bridge near Fayetteville, West Virginia. Arch bridges are one of the oldest types of bridges and have been used for thousands of years across the world. These structures can be constructed of stone, brick, reinforced concrete or steel and can span thousands of feet across wide rivers or deep valleys. The construction of arch bridges relies on the concept of compression and begins with the load

Balls Bridge and Truss Bridges: A Brief Historical Overview Nathan Holth Foreword: I composed this brief and informal overview of truss bridges and Balls Bridge to put this beautiful historic bridge 's history and significance into context. A version of this document with full-color photos is available on my website 's Balls Bridge Page located at www.historicbridges.org/ontario/balls/index.htm which also has more information and photos. The general truss bridge information in this document was

Bridge Building: Beam Bridges: A simple beam bridge that is flat across and supported at the two ends. A longer beam bridge can be held up along the middle by piers standing in the river. The weight of the bridge itself, plus the load that it carries, plus gravity are the downward forces are spread evenly across the length of the bridge. The upwards forces that hold the bridge up come from the piers. The Confederation Bridge in Canada is a famous beam bridge. Arch Bridges: A simple arch bridge

The Veteran’s Skyway Gateway to the Trent Bridge In the early 1990s, the aging swing bridge crossing the Trent River in Trenton, Ontario was replaced with a continuous span steel box girder bridge. The unique part of this process was that the new bridge was built adjacent to the existing swing bridge and slid laterally into place; this was the first time in North America that this technique had been done. The process consisted of five mains steps; first, the planning of such an undertaking, second
