Abstract

The Modal Assurance Criterion (MAC) is widely used for the validation of finite element models by assessing correlation between mode shapes from FEM and Experimental Modal Analysis (EMA). An important limitation of MAC is that it is sensitive to large values and insensitive to small values. In addition, MAC does not consider the relative response between the different parts of a FEM model. This paper introduces the Partial Modal Vector Ratio (PMVR) as a time efficient supplement to MAC for the validation of FEM models when there are correlation issues caused by the interaction of the different parts of a model. An example application is shown for a pile of three reinforced concrete beams stacked on top of each other without any bonding material.
