Auckland Harbour Bridge

A beam bridge or known as a girder bridge, is a bridge structure that consists of horizontal beams spanning supported by pillar at each end of the deck. The weight of the beam including the structure itself, plus any load it carries are supported by the downward force into the pillars. The beam bridge works on the principles of compression and tension, where on top of the bridge bends, it undergoes compression and at the bottom it is subjected to a horizontal tension. Therefore, the bridge must…

As seen in Figure 8 above, Eco Logical Australia recommends the placement of 20 road signs in areas deemed to be high risk. These areas were chosen by analysing the green lines which indicate a high risk road. The overall cost of a sign includes production, installation, and maintenance. This information was extremely difficult to obtain, therefore an estimate has been created. The base cost for a wildlife warning sign is $175 (Seton, 2017). It is then estimated that installation costs are $120…

Bridge Design: Edmond Liu My popsicle bridge is based on a truss design, which is a bridge design held up by a connected structure composed of many smaller pieces. In particular, my bridge is a variation of the Queen Post Truss Bridge, which has two central supporting posts to allow for a greater span allowing for larger contact points.

decided to do a bowstring bridge. A bowstring bridge normally are used to carry road and rail traffic. By bowstring bridges being able to use arches it makes it so that the weight of anything crossing the bridge is actually able to go straight down into the bridge instead of dispersing across the entire bridge. This makes sure that the bridge doesn’t have one spot taking on too much weight on the bridge. Bowstring bridges tend to be become stronger over time because the bridge becomes compact on…

we will look at a local organisation, the Ports of Auckland and analyse the management, interaction and direct consequences of it’s publics. The Ports of Auckland (PoA) located on the Waitemata harbour, is the largest container seaport in New Zealand, with container volumes representing ‘50.38% of the Upper North Island container trade, 42% of the North Island container trade and 31.3% of New Zealand 's total container trade’ (Ports of Auckland, 2015). Along with this, PoA provide towage,…

History From the earliest of times we created bridges. Hunters needed to cross rivers and a fallen tree may come in handy.Early suspension bridge consisted of intertwined forest tendrils In Roman times they built bridges over ravines like Trajan in AD 105 that crosses the Tagus in Spain the bridge was made of granite with two massive arches 110 feet wide and 210 feet tall relative to the water.Every wedge block weighed 8 tons. Slaves organized these blocks through a system of pulleys powered by…

4 We reached Patna by late afternoon. We disembarked our bus at the Gandhi Bridge as it was known among the passengers. It is one of the longest bridges in the Asia built on the holy river, Ganges. It had made our journey pretty much comfortable. Earlier, it was a gigantic task to reach this city. You would have to use the ferries and boats to cross this mighty river. And it took many precious hours then. We put our bags and sacks of the grain on many men-drawn cycle rickshaws as it was the most…

For the purpose of this project we will be discussing mainly the truss bridge. A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. (john, 2013) A truss is assumed to comprise of members that are connected by means of pin joints, and which is supported at both ends by…

The Golden Gate Bridge is a suspension bridge. It is located in San Francisco, California, and connects to Marin County, California. To San Francisco, it’s one of the most known symbols. The construction began January 25, 1933, ended April 19, 1837 and opened May 27, 1937 which lasted for one week. The whole project cost more than 35 million dollars. Many people argued that the bridge couldn’t be built across a 6700 ft. strait, which had swirling tides and currents with 372 ft of water deep, at…
