Photogrammetric and total station's measurement of compressed column's model

Abstrakt

Modelling studies continue to play an important role. One of such study is stress determination in the reinforcement bars of reinforced columns and determine column's axis deformation. The article presents measurements results of control points located on the model of reinforced concrete column. The column was compressed in few series till it's destruction. In this studies, photogrammetric method and total station measurements were used. The main goal was to use photo points located around column with known coordinates to calculate coordinates of marked points on the column and perform surface model of the column. Based on obtained column's surface, column axis was approximated. In addition, based on total station measurements, axis approximation also was performed. There were also conducted a simplified analysis of measurement uncertainty. Based on results for each series of load, deformation over time analyses was performed. Comparison of used methods was performed. Some attention was also drawn to the factors affecting the accuracy of photogrammetric measurement.
