Photogrammetric Measurement of Deformations During the Load Test of Brick Vault

Abstract

The area of constructional element strengthening and subsequently strengthening of construction has been researched many times. These techniques lead so far to dimensional redesigning of the construction. Usage of the new technological procedures and especially utilisation of new materials allows keeping existing dimensions of the construction. This project is part of research project focused on additional strengthening of engineering construction particularly on monolithic concrete and brick construction. Integral part of project is quantitative determine of deformation, which are observed during the load test of tested constructions. Few methods where used parallel together: tensiometric measurement, electronic tacheometry, very precise levelling and digital method of close range photogrammetry. The method of close range photogrammetry was used again as a complementary method just for data comparison and for photogrammetric technology improvement in application demanding high precision.
