Abstract: 
The existing bridges become increasingly older, which leads to the fact that bridge inspections will be even more important, in the future. The assessment of the remaining useful life of bridges and the damage detection, apart from the continuous supervision of a structure investigation and the assessment methods, as well, become more relevant. Normally, the above mentioned methods are costly and time consuming.
Therefore, the University of Luxembourg carries out a project to investigate an efficient application of different assessment methods, taking into account praxis relevant test conditions. Within the context of non-destructive testing methods are static assessment methods analyzed and explained by the example of a two span box girder bridge. The presented bridge is a 102 m long prestressed concrete bridge, which was demolished after the performed tests due to a changed urban planning. Thereby the practicability of damage detections, by using static load tests, can be investigated. Within these test series the structure was damaged step by step, by artificial damage: with each damage scenario a part of the prestressed tendons have been cut, which finally lead to a local cracking. By the analysis of the load-deformation-behavior, damages can be detected and located. A statement about the level of the damage can also be made.
