Structural identification of caisson breakwater via in-situ vibration measurement
In this study,structural identification of caisson breakwater is performed by using in-situ vibration measurement and simplified model.To achieve the objective,the following approaches are implemented.Firstly,a scheme of vibration monitoring is designed for the caisson breakwater.Secondly,a simplified model is proposed to represent the caisson breakwater system.The simplified model has three degrees-of-freedoms corresponding to measurable orientations.Thirdly,a system identification(SID)algorithm is constructed to identify structural parameters of the caisson breakwater system.Finally,the proposed system identification algorithm with the simplified model is verified in numerical analysis which reflects in-situ condition of the caisson breakwater.The simplified model of the target system is generated and its structural parameters are identified by two-phase algorithm.
