MONITORING OF TRAFFIC INDUCED STRAIN IN THE STEEL REINFORCEMENT OF A CONCRETE BRIDGE DECK. 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

This report describes measurements undertaken on a steel/concrete composite bridge to determine the range of stress to which reinforcement in the deck slab of the bridge is subject under vehicle loading. The study was prompted by the proposal that a fatigue classification for unwelded reinforcement be included in British Standard BS 5400 Part 10. Code of practice for fatigue (see IRRD 245610). Measurements were undertaken with a vehicle of known weight prior to opening to general traffic and under service loading after 10 months of use. Measured strains were well below the level at which fatigue damage might occur, and were also below values that would be calculated for design purposes. The influence of surfacing and of oscillations of the bridge deck are discussed.(A) For the covering abstract of the conference see IRRD 830553.
