Modal Analysis of Civil Engineering Structures
This chapter reviews structural dynamic testing and modal analysis of civil engineering structures under controlled forces or in ambient conditions. Two main groups of modal parameter identification methods either in the frequency domain or in the time domain are discussed: input‐output and output‐only. These methods are compared for evaluating the performance for modal parameter identification under various conditions. The identified modal parameters of the tested structure are then correlated with the associated analytical model using various criteria. Because of the incompleteness of measured modal data, mode shape expansion methods or model reduction methods are introduced for correlation studies and model validations. Finally, a real case of a super‐tall structure is studied for modal parameter identification and mode shape expansion using ambient vibration measurements.
