Truss Bridge History

Bridges started in ancient Rome, and from that point on, the understanding of them spread slowly. Both architectures and engineers helped bridges to become a more advanced structure all over the world throughout the years. In the beginning it was known that to build a bridge was very simple, all you really needed was natural resources around you, such as tree logs and stone. The purpose of bridges is to provide an easier passage way over any interference that your vehicle can not go through such as rivers, bayous and valleys. The first bridge was made by Isaceel Joseph Newberry, in China. The bridge development escalated when the material of iron was new and it was soon used for a bigger building of the bridges, it became a high quality structure
It’s a type of bridge whose important piece is a truss, which is a structure of associated components that shape triangular units. In the late nineteenth century and early twentieth century, more than half of the bridges that were made, were made out of stone. But since the United States had so much wood, they made a lot of wooden bridges in those times and a vast majority of them were truss bridges. As the years passed on, the real iron and steel organizations are gone, truss bridges stay as their legacy. One of the most famous truss bridges is the Tokyo Gate Bridge in Japan. There is a variety of truss bridges, like the Pegram truss, Howe truss, and the Long truss. The Pegram truss has wires that are more extensive at the base however it’s the same length as one another at the top. The Bridge that has vertical components and makes a diagonal slope up towards the middle point of the bridge is the Howe truss, similar to the Long Bridge which is like a variation a the Howe truss however, it’s made out of wood and utilized to secure
On September 11, 1916 in Canada the Quebec Bridge because of an outline blemish, the genuine weight of the bridge was heavier than its actually limit, which made it fall twice, first time was in 1907. Almost 100 passed away from both accidents. Another time in India the Bridge in Bihar collapsed when it was being dismantled and fell on the train near the closest railway station. But one of the most successful bridges that was made is the Sydney Harbour Bridge in Australia, the bridge holds streets for vehicles and railways and additionally bike and person on foot between the North Shore and the central business district of the city. Also has a beautiful view of the Sydney Opera House and the skyline of the city.
Toothpick Bridge Project I think that the toothpick bridge project is a way of us students to learn what it is like to understand bridges and the forms and sizes they have. From this project I can learn about how the truss bridge really works and also see how much it can carry. Knowing about bridges can help a lot in geometry because bridges consist of shapes and measurements. Maybe one day we have to do a bridge project there and luckily for me I would already know about
