Abstract: Simple general formulas are derived for investigating the effect of errors in a priori statistics on the minimum-variance estimates of linear regression parameters from observations obscured by ...

Abstract: The concept of power flow, which has been found to be a powerful tool in the dynamic analysis of complex systems with conservative connecting elements, is extended to the case of nonconservatively ...

Abstract: Linear quadratic regulator (LQR) formulation has been used extensively in many control systems designed for structural control applications due to its stability and robustness. However, recent results obtained from simulation, ...

Abstract: The methodology and theoretical development of damage identification through the regularization method are described. Numerical studies of a two-degree-of-freedom and a 10-degree-of-freedom shear-beam-type structure and ...

Abstract: This paper presents a solution procedure for damage identification through measured structural response. The cost functional employed is based on the regulation method for inverse problems. An optimization procedure using ...

Abstract: In this technical note, power flow between two oscillators with spring and damping (nonconservative) couplings is introduced, and its relationship with energies stored in the two oscillators is established. It is shown ...

Abstract: Exact solutions are presented for the mean-square responses of a class of complex structure-equipment systems under dynamic loads. The complex systems consist of an

Abstract: A condensation procedure for the coupled analysis of multidegree‐of‐freedom primary‐secondary (PS) structural systems is developed based on energy principles. It provides a simple and consistent approach to the response ...
