| Abstract: | A Digital System to Record and Analyse Cracks A digital system – ready for its practical use – is presented to precisely record and analyse cracks at concrete or masonry structures. It uses a standard digital camera and a specific cylindrical attachment to photographically record crack pattern at surfaces. Crack parameters like medium widths, width variations or width profiles are analysed from several dozen measurement points per centimetre of a crack using a developed software tool. Applications on site – like bridge evaluations acc. DIN 1076 – and in the lab – like monitorings of shear crack developments – illustrate handling, precision and data extent of the system in comparison to standard methods. |
