Warren Truss Bridge Design

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.

Each separate truss (of the dimensions 920x5x50mm) consisted of a Pratt truss with nine diagonal members on each side of the centre. The model was tested in sufficiently isolated condition by tutors. It successfully passed the initial weight test, and satisfactorily resisted horizontal forces. Once fitted onto the testing rig, loads were applied and increased incrementally. Slight deformation was observed before failing at 12.5 kg, at which force a collection of members failed in succession, concluding the test.

In our reading, there were many things that jumped out to me, but I wanted to touch on a couple of them. Firstly, I wanted to discuss the whole idea of “the bridge” in the story. On page 11, at the end of the 2nd paragraph, Carnehan talks about how he came to the first village. Carnehan speaks of how he and Dravot arrived “without any trouble”, and then proceeds to explain how they gained control of the village. The idea of bridges shows up again on page 14, as Carnehan makes the natives builds bridges that “cut up the country horrid”, and finally at the bottom of page 18, as Dravot falls to his death. I feel that the “bridges” are a representation of the connections between the foreigners (Dravot

Industrial buildings and warehouse buildings because of the ability to create large span spaces at a low cost

Brunel’s solutions were groundbreaking and critics often questioned his designs. The Clifton Suspension Bridge had the longest span of any bridge in the world when it was completed; the Maidenhead Bridge was both the largest spanning brick arch bridge and the first to use a flattened arch form; and the Royal Albert Bridge was built using lenticular iron trusses.

Since the early days, the men try overcome environmental challenges and, in this process, ends up creating amazing masterpieces of engineering. Among this works, the bridges appears as the clearest representatives of how the mankind could adapt to Earth’s contours. If the shape of landscape can’t be changed, the bridges are the solution to link two places and allows the connection of the traffic to improve aspects such as the communication and the trade. Depending to the need, to the sources and to the environment, the bridge can be constructed in a specific configuration. There are five main sorts of bridges configurations. First, there is the simplest bridge, the beam bridge. Second, the arch bridge, one of the oldest kind. There are the truss, composed of set of trellises. Lastly, there are the cable-stayed and

The truss bridge I will focus on is Hampden Bridge, located in Wagga Wagga, New South Wales. Hampden Bridge is a wood Truss bridge that crosses the Murrumbidgee River in Wagga Wagga, New South Wales. This bridge opened to the public on 11 November 1895 and it was closed in October 1995 due to Wiradjuri Bridge opening. The bridge is 100.5 metres long, all of the 3 truss spans 33.5 metres. Hampden Bridge is the first large overhead-braced truss bridge made by Percy Allan. The bridge was originally designed to be a steel, but the tenders were too expensive. timber was used as the alternative. The Hampden bridge replaced the Wagga Wagga bridge,this bridge was made in 1892 and alos crossed the Murrumbidgee river. Percy Allan made the third of five standard wooden truss bridges. there is a clear difference of development between the pre Allan era and the post Allan era. Allan completely redesigned how timber truss bridges were made in NSW. He often based his bridge design on the American Howe bridge although he exploited the much stronger woods in Australia, to reduce the design its bare essentials, this is show in the differences between the two bridges before Allan made his and Allan’s bridges all around New South

Truss bridges have been around for a long time. I see truss bridges the most out of all the different types of bridges and to me it seems like the most popular type of bridge. In addition there are thirty different types of Truss bridges which means that there is a bigger variety of Truss Bridges instead of just having one type. Truss bridges have triangular shaped beams that go all across the bridge. The bridge also is above the roadway instead of under the roadway like the arch bridge. Truss bridges could also stretch very far. The longest cantilever Truss bridge that goes is called Crescent City Connection and it is 13,418 feet long with a width of 52 feet. There is also a really long Truss bridge that is near Hoboken, the name of the bridge

To accomplish the task of building a bridge out of popsicle sticks and elmer's glue, I designed and built a truss bridge. Once completed, it weighed 237 grams, and spanned 26 inches, with a height of 7.25 inches.

placed on the other direction at the end of the cantilever, and also to provide

There are several characteristics for the king post truss. King post truss is generally found in wooden frame buildings when there are large spaces are needed and not using the column. It is characterized by two diagonal pieces of wood or metal which ends are stabilized on the end of a chord above the ground. Besides, the design of this truss is simple and takes less timber and metal. Therefore, it cost lower than other truss and also extremely

The Principle upon which all trusses rely is that the triangle is the strongest and most rigid geometric Figure. By arranging the framework of triangles in patterns that varied from designer to designer, the structure acquired different appearances and served different purposes depending on the needs of bridge builders. The pony truss, the smallest type and ordinarily confined to lengths under 140 feet, with most under 100 feet, is distinguished by its low profile and absence of bracing above the roadway. The through truss by comparison is greater in length and height and consists of a tunnel-like structure that carries traffic through a system of overhead bracing which ties together the upper chords of the bridge.

Trusses are triangular shaped support beams that attach point-side down to the roadbed of the bridge on either side. This structure distributes the force of the weights to the bridge. These bridges are a lot like beam bridges, but stronger and it is perfect for heavy loads and small distances. In addition, triangular trusses will work, but will drastically decrease the weight or load your bridge can hold. (To make your bridge even stronger, attach short pieces of spaghetti to the points of the trusses to make small triangles - trusses for the trusses.) Also, the triangular shape is the best method of construction than rectangular shape as there is no bending because the bridge is strong.

Because of advancements in today’s technology in construction field, many types of bridges are being constructed depending on the requirement and their suitability for the situations.

Gillum-Colaco International Inc. made structural drawings and the initial sketches for the walkways showing some of the design criteria to be used for fabrication, but the latter was not provided to the fabricator (Havens Steel Company) (Brunet, 2007). Once the fabricator had received the information which was incomplete, the design of the box beam-hanger rod connection was redesigned. Havens’ model was based solely on the AISC manual and did not take into consideration load bearing calculations and other specification that would have been given by the structural engineer. The Haven Steel Company then
