Role Of Engineers During The Planning Process

This spectacular bridge is 8,981 feet, or 1.7 miles, long. The total weight of the bridge is about 887,000 tons. The two towers stand 726 feet above the water and 500 feet above street level. They weigh

When bridges are poorly constructed, they may fail due to load they carry, collision by derailed trains or even by vehicles that lose control leading to catastrophic incidences. However, if bridges are well-constructed, the chances or injury are greatly minimized in the event of an accident. Discussed in the subsections are the requirements of AS 5100 standards in relation to cable-stayed bridges and include design requirements for bridges, bridge aesthetics, bridge functional requirements, bridge component design requirements and bridge construction

The $23 million Goodwill Bridge gives a person on foot and bike a crossing over the Brisbane River interfacing the Southbank Parklands to the Brisbane Botanical Gardens. The most unmistakable component of the 470m long engineering composed extension is the 102m double curve arch between the south bank of the waterway and the primary structure amidst the Brisbane River.

In the middle of nowhere, in that vast expanse of trees, lies The Bridge. Nobody knows it as any other name. It stretches across the Dead River, just sitting there waiting for someone new to find it. At one time it was driven over constantly, a way of travel for the inhabitants who are crazy enough to live out there. But now it is just there, a giant chunk of metal, rusting away into nothing. Occasionally it is used for things like fishing, or as a

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

The Peace Bridge. An international bridge between Canada and the United States. The Peace Bridge is located near the center of downtown Buffalo, New York, and Fort Erie, Ontario, where it crosses the Niagara River. It seems like a ordinairy bridge that was made back in 1927. But behind the beauty of a such long creation is hundreds of year history hidden.

Since then, I have taken the Queensboro Bridge hundreds of times. Spanning across the East River and looking out onto the city skyline, the bridge still serves the same purpose today, as it did in 1909 when it was first opened. To most people, it looks like any other bridge, but to me, it’s like watching parts of an ecosystem work together as people bike, walk, and drive across and around it.

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.

What is peace? To me peace is non violence, The act of not killing and solving issues formally in person or on paper. Peace cannot be implemented if we are killing other people and countries and letting our neighbors and love ones die. If we can prevent people dying then what is stopping us? Negative peace is when violence ends. While positive peace is where it ends but brings either a change for the better or is positively impacted.

The Brooklyn Bridge became a symbol of modern world, and is represented in poetry and art. In 14 years, 600 workers, 2 dozen lost lives, and 15 million dollars later it was finished. As well as having the longest span in the world at 1,600 feet from tower to tower, it was the first ever steel suspended bridge. John Augustus Roebling was the pioneer of this piece of art. Roebling is credited with being the first to use steel as a component in his bridge design. Roebling has inspired many pieces of art and structures that we know of today.

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.

A bridge is a structure providing path over an obstacle. When constructing a bridge, obstacle can be a river, railway track or a valley and the path provided by bridge can be for a road, pedestrians, a railway, pipelines, viaducts to carry water from rich areas to dry cities, or for commercial purpose to host commercial buildings such as restaurants and shops. A bridge can also be laid to reduce the distance of travel which in turn reduces the time to reach the destination.
