Establishment and Application of the Wind and Structural Health Monitoring System for the Runyang Yangtze River Bridge

open access: yesShock and Vibration, Volume 2014, Issue 1, 2014., 2014
Structural health monitoring can provide a practical platform for detecting the evolution of structural damage or performance deterioration of engineering structures. The final objective is to provide reasonable suggestions for structural maintenance and management and therefore ensure the structural safety according to the real‐time recorded data.

Traveling Wave Resonance and Simplified Analysis Method for Long‐Span Symmetrical Cable‐Stayed Bridges under Seismic Traveling Wave Excitation

open access: yesShock and Vibration, Volume 2014, Issue 1, 2014., 2014
The seismic responses of a long‐span cable‐stayed bridge under uniform excitation and traveling wave excitation in the longitudinal direction are, respectively, computed. The numerical results show that the bridge’s peak seismic responses vary significantly as the apparent wave velocity decreases. Therefore, the traveling wave effect must be considered
