Method and apparatus for strengthening/restoring a reinforced/prestressed concrete structure |
摘要 |
A reinforced or prestressed concrete structure is strengthened and/or restored by attaching a strip-shaped tensional member thereto. Prior to attaching the tensional member, a central portion thereof is prestressed. Then, the tensioned central portion is bonded to a concrete surface of the concrete structure by a first adhesive having a high deformation modulus. Thereafter, the non-prestressed end portions of the tensional member are bonded to the concrete surface by a second adhesive having a low deformation modulus, whereby the second adhesive is substantially less deformable than the first adhesive.
