Suspension Bridge at Location D Essay

It perceives the crossing of the Brazos River. [In 2008, the first pieces of the “Branding the Brazos” sculptors made their debut Next to the bridge. The towering Chisholm Trail sculptures, crafted by Robert Summers, include An oversized, bronze trail boss driving longhorns on their way to crossing the Brazos.] (waco-texas.com) Use to when livestock had to be taken to market they had to rely on the ferry which was Dangerous and it took a lot of time to get the livestock across. But they built a suspension bridge. This bridge was open to the public in 1870. And it is older than the Brooklyn Bridge. [The Waco Suspension Bridge is a 475-foot structure that crosses the Brazos River in downtown Waco. At the time that it was built it was one of the longest single-span suspension bridges in the World. The bridge served vehicle traffic until 1971, at which time it became reserved for pedestrians and special events. It was listed in the National Register of Historic Places in 1970

Suspension bridges usually experience torsional forces during very windy conditions where there are high wind speeds, this can create a twisting force causing the deck to rotate resulting in the bridge experiencing shear stress. (Bagga

Initially, suspension bridges before 1940 were made of piers, towers, wires, anchorages, and roadways. Piers were the main foundation for the suspension bridges. There usually were two of them, which were made out of cement and were entrenched in ground underneath the body of water that the bridge was spanned across. Towers were built on top of the piers to provide a means of connection for the roadways and wires. Wires were connected to the towers, roadways, and anchorages to provide tension support for the weight of the bridge. The anchorages were large cement platforms that were planted into the ground on either side of the land so that the wires could be connected to it. Lastly, the roadways were the main point of the suspension bridge. They usually were wide enough to provide four lanes of traffic and stretched from one side of the bridge to the other. This was the basic design of the suspension bridges

In Washington, the Interstate 5 bridge, which crossed the Skagit River, collapsed last month. The damage of this accident included two cars broke and three persons injured. According to officials, the bridge fell into the river after the large truck hit a beam. The bridge had a risky condition called facture critical. The U.S has a lot of bridges; however, nearly two thousand bridges were built between the middle of 1950s and the 1970s, so those ones are obsolete bridges. In addition, back then, the government cut corners in bridge buildings to cost reduction. Although gas and diesel taxes attempted to allocate to restored the bridge, the government cloud not collect money enough to repair the bridge because people began to use efficient vehicle.

Currently working on its segment, Waxhaw, N.C. will build a 200-foot suspension bridge to connect to the trail.

The final primary component of a suspension bridge is the deck, or the roadway upon which cars drive and pedestrians walk. The deck is built from massive pieces of steel-reinforced concrete hoisted into the air and laid into place upon the bridge. Deck pieces are connected with bolts and rivets, then suspension cables connect each section of deck to the main

We think this because the more gravel was added the more it started to bend. until it suddenly snapped. The bridge broke more to the left side close to the platform. As you can see in this picture ( point out picture on poster) The bridge broke because of its lack of popsicle sticks supporting it. The cardboard alone was not strong enough. If we were to use a material like wood, the bridge could have withheld more weight.

The Causeway Bridge spanning Lake Pontchartrain is one of the longest bridges over water in the world. It takes a considerable amount of money to keep the bridge safe and in operable condition for all drivers to use. Local governments will likely choose to raise the price of the tolls in order to improve safety measures along the bridge; however, many Louisiana residents are upset with their elected officials for not allowing the citizens to vote on the toll price amendment.

The current Bay Bridge spans across the San Francisco Bay and through Yerba Buena Island. The reason the bridge travels through an island is because in the 1930’s it would have been nearly impossible to construct an eight mile long bridge spanning such deep water. During most of the 20th century, this island was a U.S. Navy base and in order for construction to be allowed, the approval of Congress was necessary. As a result, there was a great deal of lobbying that occurred in order to allow California the right to build across the island. After gaining the approval of Congress in February of 1931, construction started in July of 1933.

A truss is a complex structure. Each piece needs to fit perfectly to perform its role, and anything less will mean that the truss will be unstable or simply does not hold an applied load. A truss bridge requires detailed construction and knowledge of how it distributes the forces. With the lack of this knowledge your truss could fail to withstand an applied force.

The Truss Bridge by Riley and Dustin We decided to go with different types of truss bridges so that we will have a strong bridge. The truss bridges is one of the quickest bridges to put up and also is the cheapest so is could also be one of the strongest kinds of bridges. The position of the bars give it a great strength so it can hold a great amount of traffic. The unique triangle design of the bridge truss allows it to span longer distances with less swaying. Unlike the other bridges during natural disasters a truss bridge will most likely stay together and won’t shift a lot.

The bridge has a very well designed ‘sustainability’ concept, relying on upcycled materials to complete the bridge. These upcycled materials consist of the wood, the fishing net, the oil barrels and the plastic shielding for the barrels. These materials can be used for functional roles in the design, such as platforms, floatation, safety lines across hand rails, and so on. The bridge’s sustainability concept can be further supported by the ease of replacing materials, and not throwing them in the bin. The materials such as wood, plastic and pieces of metallic bolts and nuts can be recycled and reused for other purposed such as furniture, storage or completely recycled back into a molten form for the metallic objects.

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 of what makes it unique to other bridges. In the early nineteenth century a majority of bridges was consisted of stone, but wood and iron were better than resisting tension, this is why the United States had many Truss bridges. Truss bridges can also be built basically anywhere. These bridges can span far or short as they want while maintaining structural integrity. To describe the Truss bridge in a few words or phrases, I would say that they are very economically friendly, strong, light, and very versatile.

I would like to express my gratitude to Amity School Of Engineering and Technology for giving me the opportunity to study and analyse the process of making a bridge and promoting me to working on the site. I would like to thank The Jammu & Kashmir Construction Corporation Ltd. for guiding me through the process of constructing a bridge. I am grateful to my Faculty Guide Mr. N.B Mishra for his supervision, guidance and constant help. I would like to thank my parents and my friends for their constant encouragement.
