When structural dynamic design for smart control and health monitoring is executed,
imposed excitations on structures are one of most important issues in structural engineering …

Unknown initial conditions can affect the identified accuracy of dynamic forces. Direct
measurement of initial conditions is relatively difficult. This study proposes a sparse …

Identifying impact force from measured structural responses has been extensively studied.
Contact sensors such as accelerometers are often applied for recording the structural …

The classical function expansion method based on minimizing l 2-norm of the response
residual employs various basis functions to represent the unknown force. Its difficulty lies in …

This contribution deals with extraction and analysis of the transient component of a
deployable structure vibration based on the sparse decomposition with mixed norms. The …

An accurate input-output mathematical model is the basis of moving force identification
(MFI). However, an absolutely accurate mathematical model between moving forces and …

This paper presents sparse and low-rank methods for explicit modeling and harnessing the
data structure to address the inverse problems in structural dynamics, identification, and …

The strength and integrity of a structure are determined not only by the quality of its
materials, but also by the health of its various components. In some cases, damaged cracks …

Impact force identification is important for structure health monitoring especially in
applications involving composite structures. Different from the traditional direct measurement …

Most load identification methods require that the load location is known in advance. A
sparse Bayesian framework is proposed in this study to identify the force location and time …
