摘要:
A concrete structure member strengthened with prestressed FRP elements includes a concrete structure body and a prestressed FRP element arranged on the former. An epoxy resin overlay surrounding the prestressed FRP element is provided to wrap it up, and a polymer concrete supplemental layer is provided outside the epoxy resin overlay. The concrete structure member can uniformly and effectively transfer the stress from the prestressed FRP element.

摘要:
An anchoring method for external bonding and reinforcing technique with prestressed fiber cloth mainly involves the following steps: stretching fiber cloth (1) on the surface of a reinforced member (2) firstly, and then bonding the prestressed fiber cloth (1) and the reinforced member (2) as a whole with resin. In addition, certain measures of installing a steel plate (5) for anchoring and using an anchor device (7) are applied to the anchorage end of the prestressed fiber cloth (1) on the end of the reinforced member (2). The prestress on the anchorage end of the prestressed fiber cloth (1) is partly or all released after thermosetting of the resin so as to eliminate or reduce the stress concentration on the end.
