Stochastic subspace identification of modal parameters during ice-structure interaction. [PDF]
Philos Trans A Math Phys Eng Sci, 2019 Identifying the modal parameters of structures located in ice-infested waters may be challenging due to the interaction between the ice and structure. In this study, both simulated data from a state-of-the-art ice–structure interaction model and measured data of ice–structure interaction were both used in conjunction with a covariance-driven stochastic

Deterministic - Stochastic Subspace Identification for Bridges [PDF]
2007 IEEE/SP 14th Workshop on Statistical Signal Processing, 2007 System identification for structural engineering has received significant attention in the last thirty years. With the ever increasing capacity of computing technology, system identification has been applied to important structures such as bridges and aircraft. In the case of bridges, the output can easily be measured by accelerometers.
