RISSystem Decoupling Approach for 3-DOF Bridge Flutter Analysis
Publisher: American Society of Civil Engineers
Abstract: A novel system decoupling approach (SDA) that enables three degree-of-freedom (3-DOF) bridge flutter analysis is proposed in this study to simultaneously investigate the relationships between modal parameters and 18 flutter ...
Direct Approach to Extracting 18 Flutter Derivatives of Bridge Decks and Vulnerability Analysis on Identification Accuracy
Publisher: American Society of Civil Engineers
Abstract: The extraction of 18 flutter derivatives of bridge decks from three degree-of-freedom (3-DOF) free vibration data using a novel direct approach is addressed in this study. Different with many conventional methods that ...
Three-Degree-of-Freedom Coupled Numerical Technique for Extracting 18 Aerodynamic Derivatives of Bridge Decks
Publisher: American Society of Civil Engineers
Abstract: A three-degrees of freedom (3-DOF) coupled numerical simulation technique for synchronously extracting 18 aerodynamic derivatives of bridge decks is proposed and evaluated in this study. Computations are performed with a ...
