Using Experimental Dynamic Modal Analysis in Assessing Structural Integrity in Historic Buildings

Abstract

The research optimizes the use of the dynamic modal analysis based on experimental data as a non-destructive approach in identifying the structural integrity of historic buildings. Currently dynamic modal analysis is widely used to global understand displacements of construction given their size and structure. This research proposes to simplify the ways in which to assess the structural conservation management required for historic buildings including complex monuments. The simplified approach suggested in this research is based on using ambient vibration as the excitation and the use of accelerometer sensor applied in appropriate configuration. The proposed approach, would provide a more expeditious methodology in assessing structural integrity than other methods. The research validates the results achieved with the Experimental Dynamic Modal Analysis (EDMA) methodology by comparing experimental results with those achieved with comparable FE assessment.
