WebThe design of a truss bridge incorporates a triangular structure called ‘truss’. Construction of this kind of bridge is based on smart use of compression and tension. Truss bridges are the oldest known bridges of the modern era. They are constructed by connecting elements/units through compression, tension or both. WebA post tensioned slab can be identified by the grouting of the live stressing end of the cables. Once the cables are tensioned and grouted, the live ends where the jack applies the stressing is also grouted. The grouting is usually a different mix to the concrete slab itself so usually has a different colour.
