TY - JOUR T1 - Modal analysis quality identification methodology applied to wall-elements A1 - Mariusz Żółtowski JO - Acta Sci. Pol. Architectura} VL - 20 IS - 3 SP - 20 Y1 - 2021 UR - https://www.architectura.actapol.net/volume20/issue3/_3_.pdf SN - 1644-0730 KW - coherence function, experimental modal analysis, stabilization diagram, wall element AB - New recommendations and norms in civil engineering show a need to control the quality of wall elements; the quality control demands guidelines to fit requirements of mass-production of wall elements. This article develops an approach which applies advanced calculating techniques used for wall-structural analysis. The paper proposes a diagnostic methodology which can be added to regulations and standards based on experimental modal analysis methodology. ER -
