Abstract
At the Faculty of Civil Engineering, the University of Maribor, in the Centre for Geodesy, we have been primarily dealing with the study of displacements and application of results on deformations and mathematical analyses for the last 10 years. According to these results, we wanted to find a connection between displacements and resulting deformations in mathematical terms. For this purpose, experimental load-bearing test of a concrete girder was carried out step by step up to crack. Additionally, concrete girder was analytically modelled and also photogrammetric, geodetic, and physical methods were compared. During the process of analyzing the results, further polynomial interpolation was performed through which the displacements in the intermediate stages were calculated. Polynomial interpolation can also help in accomplishment of load-bearing experiments of larger structures.
