Paper Abstract

The experimental investigation is described of the reinforced concrete construction pro blems mentioned in the title, making use of the Laser-Speckle-Photography optical measurement method- Proceeding from the material-conditional particularities and the high demands on the accuracy of the measurement values, a semi-automatically working device. was developed for analysing the Laser-Speckle photographs. The method of working with this device, the statistical routines applied in the process and the attainable accuracy are reported on. Moreover, reference is also made to the strains in a reinforced concrete member and the crack. formation. In the last section, the results of measurements of the joint rotation on the inner support of a two-span beam of reinforced micro-concrete, as well as the shear bearing behavior observed in this context, are discribed.
