ASSESSMENT OF PRESTRESSED BRIDGE BEAMS. BRIDGE MANAGEMENT. INSPECTION, MAINTENANCE, ASSESSMENT AND REPAIR. PAPERS PRESENTED AT THE FIRST INTERNATIONAL CONFERENCE ON BRIDGE MANAGEMENT, UNIVERSITY OF SURREY, GUILDFORD, MARCH 28-30, 1990
A number of pretensioned beams have been recovered from an M63 underbridge during demolition. They have no link reinforcement in the web. For this reason, if assessed using BS 5400: Part 4, (see IRRD 282725) they would not comply in shear. This paper contains a description of shear failure tests carried out on the 16 m long beams. The results indicate that the beams possess reserves of strength because of conservative assumptions in the method of calculation and the high strength of the concrete. Whereas it may be prudent to provide a minimum amount of shear reinforcement in the form of links for new design, there is a strong case for dispensing with this requirement in some assessments.(A) For the covering abstract of the conference see IRRD 830553.
