Explain The Final Primary Component Of A Suspension Bridge

1. On Thursday, 15 December 2016, at approximately 1259hrs, I, SFC Brown-Horne 1CD RSSB SARC, received an email from SFC Woodard, Michael, (Collateral duty SARC for 553rd CSSB) requesting information about a formal complaint file 22 July 2016. This complaint was filed prior to the 1st Cavalry Sustainment Bridge deployment to Afghanistan. SFC Woodard informed me that, 1LT Schwartz stated that her informal complaints was not closed out properly. I, SFC Brown-Horne, replied to SFC Woodard replied in an email stating that COL Colavita did back briefed her on the closure of the case and his recommendations. I was present during that meeting on VTC. The COL informed 1LT Schwartz that the case was substantiated, he was relieved from command, and was given a letter of reprimand.

The original design of the bridge was a two cell prestressed concrete box girder with three main spans (as mentioned above). However, as most of the water's commercial and pleasure boats use no pilot or tug, the potential environmental impact of a pier collision with possible subterranean damage, was deemed unacceptable.

A simple beam bridge that is flat across and supported at the two ends. A longer beam bridge can be held up along the middle by piers standing in the river. The weight of the bridge itself, plus the load that it carries, plus gravity are the downward forces are spread evenly across the length of the bridge. The upwards forces that hold the bridge up come from the piers. The Confederation Bridge in Canada is a famous beam bridge.

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.

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

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

A bridge is a load bearing structure spanning a passage over a gap or barrier, such as a river or roadway. Some examples of bridge types are; suspension bridge (George Washington Bridge connecting New Jersey with New York City), truss arch bridge (Hurricane Deck Bridge in Hurricane Deck, Missouri), and a cable-stayed bridge (The modern Sunshine Skyway Bridge in Saint Petersburg). Another example is a cantilever bridge (the former Sunshine Skyway Bridge). Rarely do these structures ever have catastrophic malfunctions, however, it does happen. The citizens of Saint Petersburg, Florida who have lived here since 1980 remember the collapse of the old Sunshine Skyway Bridge. On May 9, 1980, a large ship hit the Skyway in the fog and it collapsed,

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).

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 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.

This bridge was initially built back then of a combination of wood and iron but is then they started to build it with only iron. Pratt truss is characterized by having its diagonal members (except the end diagonals) slanted down towards the middle of the bridge span. (3) The sections of the bridges were called trusses, which got the name Truss. Now they build it with steel. During the 19th century and the early 20th century it was inspiring a large number of modifications and variations of subtypes. Most of Maryland’s metal bridges are made of Pratt trusses. There is more than one type of Pratt trusses which are just a few different changes in the design of the bridge. Known examples of this design in early ages are now in Maryland’s historical resource

In 2004, Moose Creek Bridge on highway 101, was the first Canadian bridge project that was fully built by prefabricated elements for both substructure and superstructure. The bridge is a single span 22 m long integral abutment bridge with overall deck with of 14.64 m. Prefabricated restressed slab-on-girder T-shaped beams was used for construction of superstructure (Canadian Civil engineering 2011 Accelerated Bridge Construction).

“An inhabited Bridge – in addition to its primary function of surmounting natural or man-made obstacles, be they rivers or canals, railways or motorways – serves as an organic link between two urban areas by connecting them to each other with a development of buildings erected on the bridge deck to form permanent accommodation for various social and economic activities. Thus, every inhabited bridge consists of two elements: the platform that spans the obstacle and an architectural superstructure. In contrasts to a purely vehicular bridge, the inhabited bridge provides a continuity within the urban fabric that is not only social and economic but also cultural, emotional and symbolic at a point where a natural break would otherwise exist. Indeed, it is both seductive and functional.”

(Vasani, 2011) Many components when assembled together form a bridge structure. Basic components of a bridge are superstructure or Decking, Bearings, Substructure which again consists of Piers and Abutments, Wing walls and Returns, and Foundation.

This report gives a summary of the role of bridges as anchor points in route choice modeling. This work expands upon the prospect that people dispense more substantial amounts of significance to some specific highlights of the route, so-called anchor points. By this report, we contend that the thought of both route level attributes and anchor points would upgrade the behavioral part of route choice models and additionally their estimation and forecast capacities would be of great help. Past route choice models have either overlooked the impacts of anchor points (route based models) or have given a restrictive regard for their belongings and disregarded the behavioral of anchor-based models. The implications of bridges
