RISHigh-Dimensional Uncertainty Quantification in a Hybrid Data + Model-Based Submodeling Method for Refined Response Estimation at Critical Locations
Publisher: ASCE
Abstract: This study presents frameworks to build nonintrusive polynomial chaos expansion (PCE) models with regression and Smolyak sparse-grid quadrature to perform high-dimensional uncertainty propagation and uncertainty quantification ...
STRIDE for Structural Identification Using Expectation Maximization: Iterative Output-Only Method for Modal Identification
Publisher: American Society of Civil Engineers
Abstract: This paper introduces structural identification using expectation maximization (STRIDE), a novel application of the expectation maximization (EM) algorithm and approach for output-only modal identification. The EM algorithm ...
Structural Identification for Mobile Sensing with Missing Observations
Publisher: American Society of Civil Engineers
Abstract: There are many occasions in structural health monitoring (SHM) on which collected data sets contain missing observations. Such instances may occur as a result of failed communications or packet losses in a wireless sensor ...
Sensitivity Metrics for Maximum Likelihood System Identification
Publisher: American Society of Civil Engineers
Truncated Physical Model for Dynamic Sensor Networks with Applications in High-Resolution Mobile Sensing and BIGDATA
Publisher: American Society of Civil Engineers
Abstract: Historically, structural health monitoring (SHM) has relied on fixed sensors, which remain at specific locations in a structural system throughout data collection. This paper introduces state-space approaches for processing ...
Generalized Response Surface Model Updating Using Time Domain Data
Publisher: American Society of Civil Engineers
Abstract: In finite-element (FE) model updating using response surface (RS) models as surrogate, the procedure of finding an appropriate design to build the RS models requires a number of trial-and-error approaches with different ...
