It was In America, however, that the truss girder was create to its modern day form In 1847, Squire Whipple developed the iron truss, a approach pattern that carried on to the twentieth century In 1849, the famous English engineer, Robert Stephenson, developed the Bowstring Girder.
In 1850 Stephenson collaborated with others to complete other important type of Beam Bridge. In 1867, Heinrich Gerber built the low balanced cantilever bridge over the River Main in Germany. In 1879 the Tay Bridge (on the alike rail line as the forth Bridge) was built 1948 saw the using of one of the most normally used beam tie today, the box girder bridge. slopped Bridges Masonry Arch Bridges The stone arch bridge was used extensively by Roman engineers from 200 BC to cd AD The oldest Roman bridge is the Ponte Rotto in Rome The biggest Roman bridge span was 42m on a 4 span viaduct in Narni, on the Via Flaminia....If you want to ca-ca a full essay, lay out it on our website: Ordercustompaper.com
