The accuracy of laboratory research data is crucial for ensuring the reliability and the robustness of experimental findings. Establishing data accuracy builds confidence in the analysis and supports the validity of research objectives. One method for assessing the reliability of test data is the use of regression analysis. However, such analysis requires appropriate and meaningful parameters. One key parameter is the drift ratio, which represents the lateral deformation of a test specimen subjected to horizontal forces. When correlated with other data, it enables the determination of the displacement ductility (μΔ) of the structural element. Furthermore, from the measured lateral displacement (Δ), the elongation and the shortening of the column’s vertical sides can be analyzed to calculate the curvature (φ), which describes the change in cross-sectional shape. Since displacement and curvature co-occur, a logical relationship exists between them. This relationship can be used as an indicator of the consistency and strength of the research data.
