The collapse of the 1940 Tacoma Narrows Bridge stunned everyone‚ especially engineers. How could the most "modern" suspension bridge‚ with the most advanced design‚ suffer catastrophic failure in a relatively light wind? The State of Washington‚ the insurance companies‚ and the United States government appointed boards of experts to investigate the collapse of the Narrows Bridge. The Federal Works Administration (FWA) appointed a 3-member panel of top-ranking engineers: Othmar Amman‚ Dr. Theodore

Unfortunately‚ natural disasters have come to destroy such bridges on many occasions. One of the most deadly natural disasters to face the bridges is earthquakes. The movement of the ground causes the supporting beams and columns to twist and collapse‚ often resulting in injury or death for

cut or shaped before use. Post and beam and arch structure systems were used predominately before the twentieth century‚ in places like Greece‚ Rome‚ and Egypt. The form on post-and-beam structures has to due with the materials used. Stone beams have to be shorter and thicker because stone is brittle and not flexible. Wood however is more flexible so they can be thiner and longer in turn they can be use to create a more open interior space. Arch structure uses stone in a semi-circle atop two columns

The Tacoma Narrows bridge of 1940 was a disastrous‚ yet amazing‚ flawed‚ yet stunning structure. The Tacoma narrows bridge travels across the Puget Sound river‚ connecting Tacoma and the Kitsap Peninsula. It was located in Washington State‚ before tragedy struck. The bridge‚ the 3rd longest suspension bridge in the world at the time‚ was designed by a man named Leon Moiseff‚ helped by Elmer Maxwell Hayden‚ Clark Eldridge‚ Frederick Bert Farquharson‚ Lacey V. Murrow‚ and around 225 workers with

The Tacoma Narrows Bridge was the third largest in the world in 1940. Unfortunately that wouldn’t last too long. On November 7th‚ 1940 only four months after being open it collapsed due to violent swaying and flexing. Some of the reasons for its collapse were that it was put in an area of Tacoma that was prone to high winds and the engineer used solid girders instead of open trusses to cut costs. Another issue that engineers later learned about was its lack of aerodynamics. With that said we will

Diaphragm arches A diaphragm arch consists of a self-standing arch placed transversally in a room‚ in order to reduce the span of the room ceiling. The resulting sections can be covered by a lintelled ceiling made of wooden or stone beams‚ trusses‚ or alternatively with barrel vaults resting on the arch and the perimetral walls.
