| 摘要 |
A structural system comprised of prefabricated deck units spaced along longitudinal load-carrying members which produces longitudinal axial compression in deck units. During construction, prefabricated deck units are erected on top of and supported by the longitudinal load-carrying members via leveling devices, which also permit relative motion between the longitudinal load-carrying members and the prefabricated deck units. Anchor assemblies are affixed to the longitudinal load-carrying members near intermediate supports. Tensioned structural elements are installed in the anchor assemblies between spans and stressed to induce tension in the longitudinal load-carrying members and subsequently produce deck compression.
