Title

The Impact Of Excitation On The Success Of Operational Modal Analysis

Abstract

Operational modal analysis on bridges and other large structures offers great promise for developing robust methods for structural health monitoring (SHM) and condition assessment. If operational modal analysis is to be used as a primary experimentation tool on large structures its limitations and uncertainties involved in real-life applications need to be well understood. Writers, in this paper summarize a study on a laboratory physical model representing a bridge structure. A number of impact and ambient tests were conducted on the structure. The sensitivity of random decrement method based modal parameter estimation to the nature of input is investigated Results show that random decrement results and corresponding modal parameters of the structure are highly dependent on the nature of the input.
