Civil Engineering EssayIntroductionThe growth and development of population, the economic and commercial progress, boast made the people to be in touch. Also, for the sales of products was necessary to build bridges as an alternative way to those people who didnt have boats to raptus their products. The bridges have been an amazing advance into the civil engineering field. As the time passed, the bridges were needed for transportation and to be used as discourse routes. The bridges have been changing as needed, either to make them more efficient or sophisticated. Now day civil engineers atomic number 18 not unaccompanied involved in the measuring, or resistance, but also they care about the aesthetic. There are different types of bridges that marked not only the biography but the progress in society. The bridges vary depending on the material with which it is built and the shape they have.Types of bridgesWood These bridges are quick to build, and are not too expensive, yet are actually resistant and durable, plus they need constant and expensive maintenance. For the ease of being built and cheap were the starting line bridges that people used. Stone They are very resistant, compact and durable. Currently construction is very expensive. They do not need much maintenance, since they are very well resistent weathering agents. Metallics They are built quickly, are expensive and have corrosion as an against factor. Also, their maintenance is expensive. Concrete and steel They allow varied designs, often agree precast, they are resistant, and maintenance costs are low. The functions that bridges have areAqueduct They are used for water conveyance.Viaducts They are built to have automobile transit.Footbridges build for the use of pedestrians only.The way bridges resist their effortsBeam They lie down of horizontal elements that are supported at their ends on supports or pillars. The force transmitted through the pillar is vertically downwards and, the refore, they are subjected to compression, the beams (horizontal elements) tend to bend as a result of the loads on. Arc It has 2 divisions. Top board, and Lower board. They consist of a curved sectionwhich rests up on supports or brackets and covering a light or empty space and depending on whether they are above or below the board, is where the arcs are located. Hanging They consist of a board by hanging by a coarse number of straps, two large cables that are anchored at the ends of the bridge and held by large towers of concrete or steel. ConclusionThe bridges have served as communication routes, and have had a serving of impact on society and commerce. Bridges are very important in the area of civil engineering, because their work as engineers is to build and make incontestable that their work is good to use, and efficient. In addition, the bridges have made the civil engineer to worry about the design of buildings and to show them that is important the aesthetic and how inn ovative is the work.
