THE INFLUENCE OF FOUNDATION BODY MOVEMENTS AND DEFORMATIONS IN QUALITY OF BUILDING CONSTRUCTION

The consequences of 'inherent deviations' (displacements, deformations and dimensional changes) of building materials are due to the effect of additional (physico-chemical) factors, influence of the assembly and position of structural elements, the outlook of the building and also the feasibility of the whole building tasks. The Department of Surveying of the Technical University of Budapest performed planning, testing and controlling work for quality control of geometric parameters on several buildings. These commissions concentrated primarily on test of movements, deformations and dimensional changes due to the effect of additional factors and also on their determination and elimination of their injurious effects. From the results measured by the Department, the experience, regarding to foundation body movement and deformation test, as well as the effect mechanism of structural dead load and payload to the vertical meant movements and deformations, is reported with the help of examples. These serve as basis for determination of forming foundation body deformations and regularities of their changes.
