PARTIAL LEAST SQUARES METHOD IN THE ANALYSIS OF THE INTENSITY OF DAMAGE IN PREFABRICATED LARGE-BLOCK BUILDING STRUCTURES

摘要

The paper presents the research methodology aimed at determining the building damage intensity index as a linear combination of indices describing the damage to its individual components. The research base comprised 129 building structures erected in the large-block technology. The study compared the results of a standardized approach to data mining – PCA (Principal Components Analysis) with the procedure of the PLSR method (Partial Least Squares Regression). As a result of the analysis, a generalized form of the building damage index was obtained, as a linear combination of the damage to its components.
