Bridge project

ABSTRACT This is model and a simplified version of Kattwyk Bridge and has been made under the constraints of space, time and resources available in the lab. The Bridge mechanism has been divided in three sections. The central section lifts above, while the two side parts remain intact with the supporting angles. The lift mechanism used for the bridge is based on the pulley system involving three pulleys. A string is passed through the two pulleys on either side of middle section and the pulley at

1922 compressed air was introduced into the shield chamber on the New York side and the actual tunneling began. Each shield weighed around 400 tons with all of the equipment in place weighing everything down. “Tunnel construction workers in this project were called “sandhogs” and are credited for saying “Think twice, you only live once.”” (Scientific American) This quote pretty much summed up the danger of working in the tunnel. Teams of “sandhogs” followed the two massive 400-ton shields removing

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

Summary We have designed a truss to support a point load, placed at 190mm from the edge of a 450mm gap. The vertical face of the trusses is modelled on the already established ‘K’ truss design, but the overall shape of the structure is our own. There are three ‘K’ units on each truss. The two vertical faces are held together at the top by another truss-like design. We modelled this on the ‘N’ truss. The truss is constructed from hot-dog sticks, glue and bolts. Introduction The task was

The Washington State Bridge and Structures office is responsible for managing Washington state’s bridge inventory. There are roughly 7,300 bridges in the state, of which 74% are concrete structures (WSDOT Web). Bridges have an average expected life cycle of 75 years. The average age of existing bridges in Washington State is 45 years old, therefore are over halfway through their expected life-cycle (WSDOT Web). To ensure safety of the public, periodic inspections and repairs must be performed to

With this project it serves to reinforce

The $23 million Goodwill Bridge gives a person on foot and bike a crossing over the Brisbane River. 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. Foundation tasks are normally planned and built utilizing entrenched points of reference. The Goodwill Bridge is an unordinary bit of framework in that the type of the structure was vigorously impacted

Truss bridge By the early twentieth century the truss bridge reflected many of the qualities of America 's industrial society: mass manufactured, steel-made, practical and unglamorous, sturdy and dependable, cost-competitive, and highly versatile. Such structures were wrote by David Plowden in his splendid Bridges: The Spans of North America, "appropriate icons to our industrialization." For the developing state of Oklahoma, steel trusses held symbolic value too, for they provided tangible proof

Brooklyn Bridge John roebling was an immigrant from germany, john did not invent the suspension bridge but his bridges made him famous in the 1800’s. As a kid roebling dreamed of building bridges, he turned his dreams into a reality. The Brooklyn Bridge was built over the East River linking Manhattan and Brooklyn. The construction of the brooklyn bridge started in January 3, 1870 and was completed May 24, 1883. The civil war delayed the construction of the bridge. At least two dozen people

The truss bridge reflected many of the qualities of America 's industrial society by the early twentieth century: steel-made, mass manufactured, practical and unglamorous, sturdy and dependable, cost-competitive, and highly versatile. Such structures were, wrote David Plowden in his splendid Bridges: The Spans of North America, "appropriate icons to our industrialization."
