Truss bridges
Truss bridges, which do not have the redundant web plate portion that girder bridges do, are an extremely rational, efficient bridge type adopting a structure made up of a combination of thin members that convey only axial force. Some types of truss bridges are named after their patent holder, such as the Howe truss, the Pratt truss, the Fink truss, and the Bollman truss. Today, the Warren truss is most widely adopted. The applied span of truss bridges is generally 50 to 110 meters, and the Quebec Bridge (Canada; 1917) is the longest truss bridge in the world, with a span length of 549 meters. JFE Engineering has great experience in manufacturing and erecting truss bridges.
