NON-CORROSIVE REINFORCING MEMBER EMBEDDING PRESTRESSED CONCRETE MEMBER

摘要

PURPOSE:To prevent members from being early deteriorated due to salt damage and improve tenacity against destruction by embedding vinylon fiber system reinforcing-members in a stretched state, under a reinforced concrete girder member, and by embedding carbon fiber system reinforcing-members in a non- stretched state. CONSTITUTION:Under a reinforced concrete girder member 1, vinylon fiber system reinforcing-members 2 are embedded in a stretched state. Besides, carbon fiber system reinforcing-members 3 are embedded in a non-stretched state. Then, against a final load, concrete members are reinforced by both the ones of the vinylon fiber system reinforcing-members 2 and the carbon fiber system reinforcing-members 3, and the using quantity of expensive carbon fiber members is saved. As a result, the span of the life of the concrete members can be lengthened.
