  • Rapidly-deployable lightweight load resisting arch system
    Patent number: 8850750
    Abstract: A rapidly-erectable lightweight load resisting system for the construction of buried arched bridges, tunnels or underground bunkers, has a plurality of lightweight arched tubular support members which are formed of a fiber reinforced polymer material and are substantially oriented in a vertical plane. The lightweight tubular support members are connected by at least one or more lateral force resisting members which are positioned in a direction perpendicular to the vertical plane of the tubular support members, and which are capable of transferring vertical loads to the tubular support members and of providing lateral-load capacity to the load resisting system. The tubular support members are fitted with one or more holes near the top which allows them to be filled with a suitable material to provide additional strength or stiffness.
