RISReview of Nonlinear Filtering for SHM with an Exploration of Novel Higher-Order Kalman Filtering Algorithms for Uncertainty Quantification
Publisher: American Society of Civil Engineers
Abstract: Recent work has shown the applicability of Bayesian inference techniques, which use a physics-based representation of the structure of interest, to structural health monitoring (SHM) tasks, such as damage identification. ...
Online Noise Identification for Joint State and Parameter Estimation of Nonlinear Systems
Publisher: American Society of Civil Engineers
Abstract: The quality of structural parameter identification in nonlinear systems using Bayesian estimators, such as the unscented Kalman filter (UKF), depends heavily on the assumptions about the state and observation noise processes. ...

Energy Capacity Criterion for the Design of Columns against Collapse
Publisher: American Society of Civil Engineers
Abstract: Current practice in buckling design is based on the ultimate strength of a member such that excessive lateral deflections do not occur. This ultimate strength is often dictated by empirically derived formulae which correspond ...
