Lattice Truss Bridge Introduction Lattice Bridge is a type of a truss bridge in which diagonally and closely linked bars are used that make a lattice. 2.3 Bridge Trusses Trusses are used in bridges to transfer the gravity load of moving vehicles to supporting piers. A lattice bridge is a form of truss bridge that uses a large number of small and closely spaced diagonal elements that form a lattice.It was patented by architect Ithiel Town in 1820 and 1835 as Town's lattice truss.. Curiously, the Sayers’ truss lacks the defining lattice structure of the braces shown in Haupt’s patent drawings. In the through type, the carriage way is supported at the bottom chord of trusses. a bridge formed by lattice girders. It has been known as the Cedar Swamp Bridge, the Salisbury Station Bridge, or simply as the Station Bridge. Haupt Truss: The Sayers Bridge in Thetford, Vermont is said to be the only example of the Haupt truss in New England. Truss is used because it is a very rigid structure and it transfers the load from a single point to a much wider area. Fun fact: the longest truss bridge in the world is the Ikitsuki Bridge in Japan, which stretches for 400 metres. The options make the truss bridge both versatile and economical to build. The K truss bridge design was a variation on another Pratt truss style, called the Parker truss. Because wood was in abundance, early truss bridges would typically use carefully fitted timbers for members taking compression and iron rods for tension members, usually constructed as a covered bridge to protect the structure. In 1820 Ithiel Town received a patent for the Town lattice truss, the first true truss that acted independently of any arch action (Hayden 1976:52-54). In 1820 a simple form of truss, Town's lattice truss, was patented, and had the advantage of … Truss Bridge - Types, History, Facts and Design.

"The Como Rail Bridge is significant as the longest single track lattice girder bridge in New South Wales and is a rare example of this type Historically, the bridge contributed to the opening up … The 154-foot Salisbury Station Bridge spans Otter Creek on Swamp Road at the edge of the Great Cedar Swamp. Disadvantages Requires a lot of space. Depending upon the site conditions and the span length of the bridge, the truss may be either through type or deck type. A Philadelphia born civil and military engineer, author, professor, inventor, and industrialist, “Haupt’s improved lattice truss bridge was a response to Ithiel Town’s 1820 and 1835 patents for the plank lattice timber truss. Lattice truss bridge synonyms, Lattice truss bridge pronunciation, Lattice truss bridge translation, English dictionary definition of Lattice truss bridge. Truss bridge is a type of bridge whose main element is a truss which is a structure of connected elements that form triangular units. By the beginning of the twentieth century, builders increasingly used creosote rather than covering wooden truss bridges. The idea of the K truss is to break up the diagonal members into smaller lengths, in the hope of reducing their likelihood of buckling under pressure. a bridge supported by lattice girders, or latticework trusses. Originally a design to allow a substantial bridge to be made from planks employing lower–skilled labor, rather … Timber truss bridges, and timber bridges generally were so common that NSW was known to travellers as the "timber bridge state".
