Modal parameter estimation from ambient data using time-frequency analysis
Abstract Modal parameter estimation of randomly and ambient excited structures using output-only system identification techniques has become a recently essential issue for assessment of engineering structures, structural health monitoring and structural control. A number of mathematical models on the output-only identification techniques have been developed in the time domain, in the frequency ...
متن کاملmodal parameter identification using ambient vibration testing with introducing a new software
the ambient vibration measurement is a kind of output data-only dynamic testing where the traffics and winds are used as agents responsible for natural or environmental excitation. therefore an experimental modal analysis procedure for ambient vibration testing needs to base itself on output-only data. the modal analysis involving output-only measurements present a challenge that requires the u...
متن کاملFrequency Domain versus Time Domain Modal Identifications for Ambient Excited Structures
Ambient vibration test is one of the most applicable and reliable methods among vibration tests due to recently fast evolvement of measurement, sensor technologies and data processing, and economical benefit as well. Modal identification methods of the ambient vibration structures are output-only identification techniques which have commonly been branched into either the frequency domain or the...
متن کاملModal Identification Study of Vincent Thomas Bridge Using Simulated Wind-Induced Ambient Vibration Data
In this article, wind-induced vibration response of Vincent Thomas Bridge, a suspension bridge located in San Pedro near LosAngeles, California, is simulated using a detailed three-dimensional finite element model of the bridge and a state-of-the-art stochastic wind excitation model. Based on the simulated wind-induced vibration data, the modal parameters (natural frequencies, damping ratios, a...
متن کاملOutput-only Modal Analysis of a Beam Via Frequency Domain Decomposition Method Using Noisy Data
The output data from a structure is the building block for output-only modal analysis. The structure response in the output data, however, is usually contaminated with noise. Naturally, the success of output-only methods in determining the modal parameters of a structure depends on noise level. In this paper, the possibility and accuracy of identifying the modal parameters of a simply supported...
