A bridge is a structure ,built by many different materials, to travel over physical objects. For example, bridges were made over bodies of water, roads or intersections, and valleys. The first welded road bridge was designed by Polish engineer Stefan Bryla in 1927.There is an average of about 607,380 bridges throughout the Unites States. There are many different bridges throughout the world and there is also different causes for bridges. There are also many different designs that all have different purposes and apply to different situations. The design of the bridge changes depending on the causes of the bridge.
There are different types of bridges that are in the world including: an arch bridge, a through arch bridge, a beam bridge, a log bridge, a Cavity wall Viaduct, a bowstring arch, a box girder bridge, a cable-stayed bridge, a cantilever bridge, a cantilever cable-stayed bridge, a clapper bridge, a covered bridge, a girder bridge, a continuous span girder bridge, a movable bridge, a pigtail bridge, a plate girder bridge, a pontoon bridge, a roving bridge, a segmental bridge, a self-anchored suspension bridge, a side-spar cable-stayed bridge, a simple suspension bridge, a step stone bridge, a stressed ribbon bridge, a suspension bridge, a transporter bridge, and trestle bridge, a truss arch bridge, and truss bridge, a vierendeel bridge, a brown truss bridge, a zig-zag bridge and last but not least a tubular bridge.
One of the most common bridges is the truss bridge. A truss bridge is a structure of connected elements forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. Another one of the common bridges is the arch bri...

... or placed there by fast flowing streams, used for crossing ponds or other watercourses. Stepping stone bridges and log bridges are known to be the oldest types of bridges. One of the last bridges, that is going to be described, is the zig-zag bridge. A zig-zag bridge is a bridge that is made up of short lengths and is set at different angles, most commonly left and right. It is used mostly for ponds and gardens.
There are many other different types of bridges that are used at least two hundred million times each day. Not all bridges should be trusted though because of all the bridges that have collapsed in the past.The pressure that acts upon the bridge affects it because if there is too much pressure on the bridge it could cause it to collapse. There are the different bridge types, what they look like, how they are built, how they work and what they are made out of.

Essay on Design A Bridge And Its Effect On The Bridge

- Introduction A bridge is required to span a gorge in New Guinea. The goal of this project is to design a bridge that meets the requirements for that bridge and then construct and test that bridge on a 1:20 scale. The requirements for the bridge are that it has to span across the 600mm (12m to scale) wide gorge which has two square flat areas on either side of the bridge which are 100mm (2m to scale) wide. The bridge must be able to hold the maximum possible weight while remaining as light as possible....   [tags: Bridge, Truss, Truss bridge, Covered bridge]

Description Of A Suitable Bridge Design Essay example

- Abstract: This report is an analysis of a suitable bridge design to span across a 300mm gap while also being able to support maximum load. Introduction: This report will investigate different bridge designs, from the gathered information a pasta bridge will be constructed replicating the bridge that: 1) Holds sufficient weight 2) Is economically viable 3) Has pleasing aesthetics The bridge must have enough deck room to accommodate a matchbox car. The bridge design that seems most appropriate will be scaled and down and constructed than tested....   [tags: Bridge, Bridges, Moon bridge, Arch]

Justifying My Choice of Bridge Design Essay

- Justify your choice of bridge design. Provide research that justifies your choice Through the many years bridge designs have changed dramatically, from few pieces of log being tied together to enormous suspension bridges span over hundreds of kilometres. As the technology and knowledge advanced the designs of the bridges became bigger and stronger. The bridge design which was chosen uses the Pegram Truss, which is a hybrid of Warren and Parker’s truss design. This particular design allows existing bridges to be recycled, meaning that the components of the original bridge can be reused and changed into the design....   [tags: Pegram Truss, civil engineering]

Bridge Design Concept Essay

- Bridge Design Concept Our bridge consists of three levels supported by 1" high cylinders to support each level. On each level we will have rows of both three and four cylinders extending across the middle. Each cylinder will be stacked on another, evenly offset and centered to gain support. Our bridge will be 28" X 2 -7/8". The length of our bridge is probably the biggest and most significant contributor to our outcome. The desk table gap is 14" long, while our bridge length is 28" long....   [tags: essays research papers]

An ethical dilemma does not have a distinct solution as no action is completely without an error in morality, in order to achieve a good outcome, it is essential to dissect the issue and identify the primary stakeholders. Before a good outcome to an ethical dilemma is achieved obstacles must be overcome through argumentation and analyzing the stakeholders.

A Review of Major Bridge Collapses and Why Essay

- ... However, none were as severe and made such an impact. Why is this. Since the Tacoma narrow bridge collapse there have been many engineers making the effort to ensure that this devastating action does not reoccur in future projects. Bridge arrow dynamics have been installed when needed in windy conditions to help dampen the effects of wind loads along with more stable support beams with stronger reinforcements. Although they cannot be completely prevented, efforts have been made to decrease the number of collapses due to heavy wind loads over time....   [tags: design, flaws, improper, wind]

I-35 Bridge in Miinneapolis, Minnesota Collapsed and Sent 80 Souls to Their Death

- ... By rechecking and revising the whole design or blueprint, a design error can be easily prevented. The Highway Accident Report, published by the National Transportation Safety board (NTSB), explains that the probable cause for the collapsed was due to a failure at the U10 gusset nodes located at the end of the main span of the truss directly over the Mississippi River. The U10 gusset plates were too weak for the amount of weight it had to hold, and calculations show how the U10 gusset plates should have been thicker so it could hold more weight....   [tags: design, calculation, weight]

Physics Of A Truss Bridge Essay examples

- Johnny Tran 11-14-14 Physics Period 4 There are many types of bridges. Some bridges has many strength and weaknesses. For example, a beam bridge’s weakness would be that you have to use a lot of stone starting up from the ground. Another example would be how a suspension bridge’s strength would be it flexibility, like the Golden Gate Bridge. The engineering process for a bridge would be to first make sure everything will be symmetrical. Secondly, from that symmetrical blueprint, the construction of the bridge is now good to go....   [tags: Bridge, Bridges, Alameda, California]

The Clifton Suspension Bridge Essay

- ... It’s been the venue for significant cultural events like the first modern bungee jump in 1979, the last Concorde flight in 2003 and a handover for the Olympic Torch relay in 2012. This bridge has made a rather small city in England notable because of its long lasting structure. The bridge towers are not identical in design. The Clifton tower has sides cut-outs, the Leigh tower has more pointed arches. The 25metre tall Leigh Woods tower stands on top a 34 metre red sandstone-clad abutment. In 2002 it was people found out that the tower was not a solid as it could but it did contain 12 vaulted chambers up to 11 metres high, linked by only shafts and tunnels....   [tags: bristol, england, arch bridge]

Clifton Suspension Bridge Essay

- Clifton Suspension Bridge The Clifton Suspension Bridge is located in Bristol England, and spans the beautiful Avon gorge. This bridge has become the symbol of Bristol much like the Eiffel tower has of Paris, and the Opera house has of Sydney. The story of the Clifton Suspension Bridge began in 1754 with the dream of a Bristol wine merchant who donated his life savings to build a bridge over the gorge. To decide on a suitable design for the bridge a competition was held. Thomas Telford, the leading civil architect of the time was the judge....   [tags: History Historical Bridge Architecture Essays]
