PERFORMANCE MONITORING OF GLUED SEGMENTAL BOX GIRDER BRIDGES. 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

Over the past 5 years three major glued segmental bridges have been instrumented for the measurement of strain and temperature. A comprehensive data base of results now exists containing strains and temperatures measured at a number of important cross-sections in each of the bridges. Since reference readings were recorded just a few days after casting, the results form a unique record for the assessment of time-dependent effects such as creep, shrinkage and loss of prestress at all stages before, during and after erection. Recent developments reported here include load testing of the structures, to provide confirmation of structural performance, and the installation of a telemetry system to enable the continuous monitoring of instrumentation to be conveniently managed from the office.(A) For the covering abstract of the conference see IRRD 830553.
