Extreme value statistics for monitoring based performance assessment of concrete structures

Abstract
Due to steadily increasing financial constrains, the life cycle cost orientated asset management in general and integral construction types in particular are gaining in popularity. Integral structures are characterized by a total lack of joints and bearings. In case of integral bridge structures the superstructure is not only missing joints but also is monolithically connected to the columns and abutments. This construction type consequently has no need for the inspection and/or replacement of bridge equipment such as bearings and expansion joints, which are typically the least durable elements, leading to reduced direct and indirect maintenance costs over the structure’s service life. However, this obvious advantage not only entails novel and complex design solutions for the transition area between structure and soil body but also leads to increased importance of the soil-structure-interaction in general, both of which are associated with high uncertainty. Within this contribution the general methodology for the performance assessment and prediction of design solutions is being presented and applied to a recently constructed jointless bridge. In particular, the interaction between abutment and earth dam is investigated. Monitoring data recorded by two extensometers, among others, during the first 30 months after construction serves as input for an extreme value statistics based performance assessment and prediction of the design assumption regarding the activated degree of earth pressure against the abutment wall.
