Abstract

Test Set-Ups on corrosion damaged cantilever walls – research project SIBS. Retaining walls such as other structures are subjected to ageing or other environmental influences. Concrete structures, and especially RC-structures, suffer from concrete spalling, cracking or corrosion. Given by slender cross sections and high degrees of reinforcement (e. g. cantilever walls) corrosion damages can influence the bearing capacity and the stability. Especially the earth-sided regions of such structures (position of the bending reinforcement) and the connection areas between the vertical wall and the foundation slab can be subjected to such damage. In these areas, a non-uniform and wide-ranging corrosion pattern can be found, which is not visible during an inspection. This report gives a short overview on (corrosion related) damages and there causes, as well as a short insight in testing methods used for the safety assessment. Furthermore, a monitoring concept for corrosion damaged RC-structures is presented. The installation and the validation of this concept is shown on a series of mock-ups and the results are compared with numerical parameter studies.
