INSPECTION, MONITORING & REHAB OF THE SAN BERNARDO VIADUCTS

Recent growth of the traffic in European road network, together with ageing of the structures have encouraged maintenance personnel to study a clever way to detect damage in concrete bridges and to develop more detailed structural rehabilitation design. Some bridge analysis methodologies are presented, based on inspection and monitoring finalised to a practical repair work management system. Some details on the Italian survey and control standards on bridges are also proposed together with some innovative way to improve the control of the bridge before and after strengthening work, based on dynamic analysis, a non-destructive technique with a less influence on traffic. The paper presents the investigation done on 31 viaducts of the San Bernardo connection road, a typical thirty-year-old reinforced concrete structure. An inspection survey, finalised to damage assessment, was carried out in order to produce a systematic approach, in other words a "bridge management system", with the aim to define a priority list of the repair works. Some examples of strengthening designs produced by Sineco S.p.A. for the repair and upgrading of the viaducts are presented. The strengthening works performed are in general oriented to solve problems on the deck and girder or on complementary elements like bearings and joints that are in general more sensitive to external agents and leakage problems that reduces the resistance of the structures. The case study presented describes problems that more or less explain the typical situation of aged concrete bridges and the solutions proposed trying to solve, in a convenient and practical engineering way, some old structural designs that have proved to be inefficient.
