  • Prestress retention system for stress laminated timber bridge
    Patent number: 5097558
    Abstract: A stress laminated timber bridge deck is disclosed. The deck includes a transversely extending laminate of longitudinally extending timbers and a system for prestressing the laminate. The prestress system includes a pair of longitudinally extending stress distribution channels disposed on opposite sides of the laminate, a number of transversely oriented threaded tension rods, and threaded members, threadably engaged with the tension rods, for tensioning the rods. A disc spring assembly is disposed on each of the tension rods and compressed between the respective stress distribution channels and respective threaded members to reduce the effective stiffness of the deck and thereby reduce prestress losses due to wood creep and temperature variation. A method for measuring prestress in a tensioning rod of the deck of the present invention is disclosed.
