Bridge

Bridges are used around the world to get over a bay of water. There are several different designs that could be used when building bridges such as arc, beam , cable-stayed, truss and suspension bridges. The Golden Gate Bridge is a very well known example of a suspension bridge. It is located in San Francisco, California. Construction began in 1933, in the midst of the Great Depression, and the bridge gave steady jobs to many people during this hard time. It was finished and opened in 1937, officially connecting Marlin County and San Francisco. The reason these types of bridges are called suspension bridges is because of two large cables, held up by two towers, are suspending a roadway. The main cables, made out of steel, extend from one…

intriguing when comparing Calatrava’s swing bridges, with the Newark Bridges completed about a hundred years earlier, is how the designers of the perspective bridges approach form and function. Calatrava has a tendency to relate his swing bridges to objects, such as the sail of a boat, as mentioned earlier, or a form of the human body, providing his bridges with a natural, more organic feel. The Newark Bridges, on the other hand, were more utilitarian and mechanical, as they were design with…

Intro; A bridge is a structure that is built over a river, road, or railway to allow people and vehicles to cross from one side to the other. (CambridgeDictionaryOnline.com) Bridges come in many different shapes sizes and designs. However there multiple different categories of bridges ranging from Arch bridge, Truss bridge, Cantilever bridge, Cable-Stayed bridge, Beam bridge and Suspension bridge, All ranging with different designs. All of the different bridge designs are made to withstand a…

Arch Bridges, Beam Bridges, Cantilever Bridges are just some types of bridges. One of the most famous types of bridges, though, are the “Truss” Bridges. The Warren Truss is one of the most famous of this category, while the Howe Truss is not as well known it is, still, a strong bridge. “Historyofbridges.com” states that “[A] Truss bridge is a type of bridge whose main element is a truss which is a structure of connected elements that form triangular units. Truss is used because it is a very…

Discussion: Bridges are affected by both internal and external forces. Internal forces occur within the bridge, through tension, compression, bending, etc. External forces are applied to the outside of the bridge, and can be static or dynamic. The static load of the bridge is the bridge itself, and the weight of its members and components. This is created by the force of gravity pulling on the members of the bridge. The dynamic load moves and changes, such as traffic, people, wind. It is created…

Beam bridges, are also known as girder bridges. They are one of the oldest and most common bridges. They are held up by river banks or piers at both ends. Box girders and trusses can help a beam bridge stay up and be stronger. Highways overpasses are normally beam bridges. The first person to build a beam bridge is not known. Although, the first beam bridges were built in ancient times. Some of the first beam bridges were built in Rome. Some of the most famous beam bridges are the Manchac Swamp…

the connection between the Hill Center and the Engineering Building, bridges have been used for thousands of years to connect people with places. As people began building bridges, they have to consider not only the structural integrity of the bridge for the safety of the passengers crossing the bridge. With the invention of cars, even more safety precautions must be enacted to keep everyone safe. A car is being driven on a windy day has a higher chance of turning over or spinning out of control…

For our design we have decided to do a bowstring bridge. A bowstring bridge normally are used to carry road and rail traffic. By bowstring bridges being able to use arches it makes it so that the weight of anything crossing the bridge is actually able to go straight down into the bridge instead of dispersing across the entire bridge. This makes sure that the bridge doesn’t have one spot taking on too much weight on the bridge. Bowstring bridges tend to be become stronger over time because the…

Bridge Design: Edmond Liu My popsicle bridge is based on a truss design, which is a bridge design held up by a connected structure composed of many smaller pieces. In particular, my bridge is a variation of the Queen Post Truss Bridge, which has two central supporting posts to allow for a greater span allowing for larger contact points.

On 1st August, 2007, an eight-lane, three-span section of the I-35W bridge over the Mississippi River in Minneapolis, Minnesota, suddenly collapsed. 145 people were injured, and thirteen died. This case study is based on an investigation of material evidence provided by the NASA Safety Center(NSC), National Aeronautics and Space administration (NASA), National Transportation Safety Board (NTSB), and a full-scale load rating of the bridge superstructure. Proximate (Direct) Cause: Gusset plates…
