A beam bridge is a very basic type of bridge. It is one large beam that is held by two abutments, one at each end. These two abutments take all of the pressure and weight that is being put on the bridge. Beam bridges need to be stiff and straight for them to work. If the bridge is not stiff enough, the whole bridge will bend and eventually break. Another main type of bridge is a truss bridge. A truss bridge is very similar to a beam bridge. It is a beam that is held by two abutments, one at each end. A truss bridge also has a truss, a structure of connected elements, on top of it. The truss’s elements are mostly triangles. This is supposed to spread out the weight. Rather than having a narrow space where all of the weight is, it makes a wider area where all of the weight can be spread out. This puts less stress on the beam. The next major type of bridge is a suspension bridge. A suspension bridge is a bridge where the deck of the bridge is hung up and supported by suspension cables. These cables take all of the weight that is being put on the roadway. The last main type of bridges is an arch bridge. An arch bridge a beam that has an arch shape underneath it. This arch shape is to reinforce the beam. Rather than taking having all of the weight push on the bridge straight down, the arch spreads out all of the weight. The weight eventually falls on the abutments, keeping most of the weight off of the beam. …show more content…

One idea was to make a truss bridge. We also had the idea to make an arch bridge. For the truss bridge. The part that is on top of the roadway had a triangle pattern. The roadway also had a triangle pattern on it. For the arch bridge, we used a triangle pattern in between the two straws that made the arch. This is to reinforce the arch since it is taking all the weight. The roadway of the arch bridge has a straight line in the center. An arch bridge was a good option because instead of the weight pushing the bridge straight down, the load on the bridge would be carried outward along the curved part of the arch. In that way, the load will be transferred equally to both sides of the arch so the bridge doesn't topple over post·haste, but again we wanted to make sure that the bridge had extra reinforcement so we used a triangle pattern. On the two sides of the line in the middle, there is a triangle pattern going across. focused in one place, so the bridge collapsed. Our third idea was to make a beam bridge. Beam bridges consist of a horizontal beam that is supported at each end by piers. The weight of the beam pushes straight down on the piers. As a result, beam bridges barely span more than 250 feet. This is because as the length of the bridge increases, the weaker the bridge becomes. With the beam bridge, we could get a clear idea of how we should position each of our straws because if we positioned our straw horizontally face down, our

Officially finished on May 24, 1883, the Brooklyn Bridge is one of America’s greatest achievements as it connected two very populous cities by land, allowing for better trade and travel. Though written differently, both “A Bridge for New York,” by Patricia Mayberry and “The Brooklyn Bridge,” from the Sun recognize the construction of the bridge as one of the most important engineering feats of the US. In “A Bridge for New York,” by Patricia Mayberry, the author elaborates more on the process of building the bridge and the hardships that had to be overcome in order for it to be built. In paragraph one, the author states, “This grueling project cost the health and even the lives of some of its builders.”

In the novel Bless Me, Ultima by Rudolfo Anaya, the bridge is a structure that connects the town and Antonio’s home, this symbolizes a connection between the two worlds of danger and safety. The bridge is described as a connection or link to the town and Anaya shows this when he writes, “I took confidence from its song, and wiping my tears from my eyes I raced towards the bridge, the link to the town” (Anaya 59). This quote shows us how the bridge is the structure connecting his home to the town. The town is an unfamiliar place for Antonio, the difference in the town is dangerous for Antonio and the familiarness of his home gives safety. The bridge is not just a literal bridge, but a passageway between to the worlds of safety and danger.

At the time one in four bridges built would fail and no one had ever attempted to build a bridge this large before, but Carnegie took on the challenge. Carnegie knew that there could be no rewards without risks and he put together a team of men to design the bridge. It would be called the Eads Bridge. (Source 8) Many concepts were scrapped and the design team soon realised that Iron was not strong enough to withstand the currents of the river. (Source 3) Carnegie knew that he would have to find something stronger than iron.

The building of the bridge is under the management of Bradfield. 3 other men are also heavily involved in the design and construction of this bridge, Laurence Ennis (engineer and man-on-site supervisor), Edward Judge (chief technical engineer of Dorman Long) and Sir Ralph Freeman (designed the accepted model of the bridge in further detail). The unemployment rate is currently very high; it is hard for me to find work in order to support my family, which is why I have been helping build this amazing man-made bridge. The construction of the bridge helped me along with many other Aussie men remain employed, although now the construction of the bridge is over I am seeking for a new job.

Notwithstanding the magnitude of the project and the technology available at the time, the building system adopted was designed specifically for the construction of a bridge. Caisson technology was used in order to dig the foundations of the bridge. Labourers excavated the riverbed in watertight retaining wood structures called caissons which were dropped into the river. Granite blocks pinned these wooden boxes down to the river floor. Compressed air was pumped into these chambers in order to keep the water and debris out.

[1]The bridge plays an important role in our life, it contributes nation’s economy due to daily transportation, which is vital for trade. Nowadays, Accelerated Bridge Construction (ABC) technique is used instead of Conventional Bridge Construction (CBC) as it reduce on-site construction time when building new bridges or maintenance of bridges, therefore lower lifecycle cost. Also, the ABC provide more pros than cons without lowering quality of the bridge. For example, it reduce the traffic mobility, it also minimize on-site construction time as segments of bridges are pre-casted so that it only need to be transported and assembled on-site. [2,3] It also has benefits of reduced total project delivery time, reduced weather-related construction
