. Drive-by monitoring enables extracting dynamic characteristics of bridges such as modal frequencies, damping, and mode shapes by using vibration responses measured on sensors mounted on a passing vehicle. Due to the mobility of the vehicle, the sensor receives the dynamic information of each point

or an undamped discretized linear mechanical system, the orthogonality is defined with respect to stiffness and mass such that normal modes are mutually stiffness and mass orthogonal. Another commonly used definition of an oscillating normal mode is that it is a pattern of motion in which all parts

asure them experimentally are time-consuming and not always reliable. Since the structural nonlinearities usually occur when the sample oscillates at high amplitudes, specimens can be damaged or at least develop fatigue cracks when the testing is lengthy. Moreover, the interaction between the shaker

ght-critical applications like aero-space engines. This approach often results in components that can have resonances in the operative range that could cause excessive vibrations and a consequential reduction of the life of the component itself. For this reason, a modal analysis check is always perf
