Clifton Suspension Bridge Essay

The clearance below ranges between the lowest point of 11.4 metres and the highest point of 12.7 metres. The arch is 102 metres in length, 10 metres wide, and 15 metres high. The bridge has a total weight of 360 long tons.

In the small town of Waco, Texas who would have thought it was once well known for the structure of a bridge, the Waco Suspension Bridge to be exact. Up until 1870, the Brazos River was just a simple river that had no special meaning to it. The land around it was empty, occasionally you would find cattlemen pushing their cattle across stream, but that was only because you could not find one bridge that spanned the eight hundred miles of river flowing through Central Texas. This caused a serious transportation issue for merchants and travelers. It became clear that a better means of crossing the river was necessary.

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

Calculations were performed to determine the effectiveness of the design of the platform. Allowing for a safety factor of 1.5 times the design weight of 10kg and considering the bridge must not be overdesigned; plans were made for the bridge to fail at 25kg, 2.5 times that of the design weight. According to the calculations, the bridge would hold a load of over 15kg and experience failure at 20kg in the members. These calculations were later disproven in the testing, breaking 8kg earlier than expected, due to unforseen errors. An analysis of the bridge design and calculations has been included at the end of this report.

Walking down gradually from University Avenue to the park area is a descent from industrial buildings to a picturesque landscape. This green space on the east bluff of the river is mature and beautiful. The topography of the soil is varies and the ancient tree trunks lift the ground up with them. The meandering concrete paths lead you beside the river, and ultimately to the Stone Arch Bridge. Where the land and vegetation open up to carve out the bridge, a grand vista emerges. The bridge leads my eye and curves smaller and smaller over the Mississippi until the rise of the Mill ruins leads my sight up and the skyscrapers eventually lift my head to the highest point of the city. Here our entire history is visible, our artifacts are in the limestone and sandstone that is manipulated to build these old structures. The wealth of the flour industry is seen reincarnated to the present day through the thriving corporate businesses in the sky. This aesthetic relationship of the Mill Ruins and new wealth is so pleasing to the eye, the interest never ends. It is mind boggling, to live in an envelope of two eras, to see what was and what has now become. How would we know our modern buildings and societies are so grand without the memory of the old?

Opened in 1999, the Garcon Point Bridge is located in Santa Rosa County, Florida. The infrastructure is a transportation route from Milton to Gulf Breeze. Citizens are complaining and threatening to boycott the bridge if the toll is raised to five dollars. Many fear encountering the absence of the extra dollar and twenty-five cents from their wallet. The standing toll is at three dollars and seventy-five. While individuals complain about the potential toll raise they neglect the thought of bondholders, who invested in the bridge, going without. Revenue statistics are at an all time low. Yes, getting from point a to b in a convenient time is ideal, the Garcon Point Bridge provides that just

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.

In the spring of 1989, the construction of the new bridge began. The base of the Trent River was a flotilla of barges carrying the workers, cranes and equipment needed to prepare the temporary pillars that would support the new bridge, as well as maneuver the huge steel girders into place for the new bridge. It was an awesome sight for the entire town, as we watched barges float the steel girders into the harbour, one section being 74 meters in length and two more that were 54 metres each. The new steel box girder bridge had a total length of 182 metres and weighed 2,950 metric tonnes (Anderson & Trenkler, 1991). Temporary cement pillars were poured to support

During the construction, two half-spans being assembled 50 meters above ground level had a misalignment of 4.5 inches or 114mm in camber. It was suggested by John Holland & Constructions to use a kentledge to weigh down the higher section of bridge. It so happened that they had ten, eight tonne concrete blocks on site. These were placed halfway along the higher span to

It is shaped in a way to transfer weight to the towers and anchors with its tension (O'Connor, 1971, p. 372). Cables are made of high strength wires spirally bound to form a rope (O'Connor, 1971, p. 372). Vertical cable suspenders that are fastened to the main cables hang the actual roadway. Stiffening girders and trusses are along the side of the bridge to distribute concentrated loads and help to keep the motion of the bridge at a minimum (Troitsky, 1994, p115).

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.

Superstructure bears the load that is being passed over the bridge and it transmits the forces caused by the same to substructure. Load received from the decking is transferred on to the substructure by Bearings. They also distribute the load evenly over the substructure material as it may not have sufficient strength to bear the superstructure load directly. Piers and Abutments are the vertical substructures which transfer the load to the earth in the foundation. Wing walls and returns are constructed as the extension of
