29 de mar. de 2024 · Carrying loads. If a bridge is unloaded, all it really has to do is support its own weight (the dead load), so the tension and compression in its structure are essentially static forces (ones that don't cause movement), changing little from hour to hour or day to day.However, by definition bridges have to carry changing amounts of weight (the live load) from things like railroad trains, cars ...
Bridge. A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or railway) without blocking the path underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross.

19 de abr. de 2024 · Construction of the Brooklyn Bridge, c. 1878. The masterwork of John Augustus Roebling, the Brooklyn Bridge was built (1869–83) in the face of immense difficulties. Roebling, an engineer, had developed his own method for weaving wire cables, which became one of the leading constructional components of his bridge designs.
From these successive parallel strands a cable was built up. Another major development in the modern suspension bridge was the pneumatic caisson, which permitted pier foundation at great depths. It was used initially by French, British, and American engineers, including Washington Roebling, who completed his father’s Brooklyn Bridge.
