History
From the earliest of times we created bridges. Hunters needed to cross rivers and a fallen tree may come in handy.Early suspension bridge consisted of intertwined forest tendrils In Roman times they built bridges over ravines like Trajan in AD 105 that crosses the Tagus in Spain the bridge was made of granite with two massive arches 110 feet wide and 210 feet tall relative to the water.Every wedge block weighed 8 tons. Slaves organized these blocks through a system of pulleys powered by treadmills.In the 12th-16th century One of the greatest innovations of the middle ages is the ability to live on bridges.
Arch bridges are a very prominent bridge. They use the arch as a main structure below the bridge depending on the sort of stress …show more content…
In 1570 four books were released detailing ways to to improve the truss bridges structure which detailed basic kingspost and queens post. And especially in the 1700s builders extensively built said truss bridges in the US.Also in the 1800s we were world leaders when it came to truss bridges.Palladio was the father of promoting wooden trusses and he was the creator of those four books in the first place. The most famous modern suspension bridges in the Us are the golden gate bridge and the Brooklyn bridge in new york. Early Suspension Bridges were erected by Thangtong Gyalpo,Tibetan saint and bridge-builder during the 15th century.He created over 58 of these structures.They were so well constructed that one of them lasted till …show more content…
It is strong and economical. It is a solid structure made up of a horizontal beam, being supported at each end by piers that withstand the weight of the bridge and the traffic. Compressive and tensile forces act on a beam bridge, which makes a strong beam essential to resist bending and twisting because of the heavy loads on the bridge. the strained placed upon the beams are transferred to the piers. The top part of the bridge, being under compression, is shortened, while the bottom portion, being under tension, is consequently stretched and lengthened. Trusses made of steel are used to support a beam. The length is a limitation of a beam bridge due to the heavy bridge and truss weight. The span of a beam bridge is controlled by the beam size since the additional material used in tall beams can assist in the dissipation of tension and compression. Steel cantilever bridges withtake heavy loads above bodies of water.To build one you must sink caissons and the erect a tower accompanied by anchorages. Steel cantilever bridges are usually made up of steel frames built out from the towers. The deck is added after
