Zusammenfassung:Purpose – The recommendation of structural standards, e.g. PN-B-03002, shows a need to control the production quality of wall-elements; the quality control demands suitable guidelines to fit the requirements of the current mass-production of the wall-elements, then, the structural standard recognizes the need of improving the methods to identify the real elements quality. The paper aims to discuss these issues. Design/methodology/approach – The proposed inspection methodology corresponds to assessment models that combine the numerical and symptomatic models to evaluate the critical levels of wall-elements, based on non-intrusive tests through the measurement of a set of signals, using the Experimental Modal Analysis (EMA)-based techniques. Findings – The presented work is developed with an approach that applies advanced calculating techniques used for the structural analysis in civil engineering focused on the technical state assessment. Originality/value – The paper proposes a diagnostic methodology that can be added to the current regulations and standards based on EMA techniques.
