Abstract：Multi-Excitation Modal Analysis was used in large structures，such as bridge, construction, aerospace industry. This paper gives a survey of the theory and application in modal parameter identification with Multiple-Excitation, Especially only in response data. Then give a deep discussion on the technique of modal parameter identification with Multi-Excitation in the different assumption of excitation signal model: Stationary Random Excitation and non-stationary random excitation. At last, the development prospect of measurement methods for parameter identification with Multiple-Excitation is summarized.
