Strengthening works to two cast iron beams on a rail bridge near Ballymoney, County Antrim has been undertaken with the complete Mapei Carboplate Ultra High Modulus Plate system on behalf of client, Translink.
To increase the bending capacity, the remedial strategy involved the removal of all defective concrete, blast cleaning of structural steelwork, replacing reinforcement in the soffit of the deck slab, and reinstating concrete using a fibre reinforced sprayed concrete repair mortar. The design engineer approached Mapei for the feasibility study of using a CFRP strengthening system to reinforce the affected steel edge girders. The study was carried out in accordance with the procedure described in CIRIA 595. Once all technical and practical aspects of the strengthening works were considered, Mapei then provided a specification and method statement for the plate installation. |
