Damage Detection of Tension Pendulums in Cable-Stayed Bridges Using Structural Frequency Variance
Publisher: ASCE
Abstract: Structural health monitoring represents an efficient way to diagnose the condition of cable-stayed bridges. Most studies assessing the condition of cable-stayed bridges and detecting damage to them have been developed to ...
Neutral Axis-Based Anomaly Detection for Local Damage to Girders Affected by Nonlinear Temperature Gradients
Publisher: ASCE
Abstract: Damage to girders threaten a bridge’s safety. They can be effectively detected by the neutral axis (NA) position of a girder. However, the NA position is inevitably affected by the nonlinear temperature gradient of girders, ...
Early Warning Method for Bearing Displacement of Long-Span Bridges Using a Proposed Time-Varying Temperature–Displacement Model
Publisher: ASCE
Abstract: Bearing displacement is a necessary monitoring index for a long-span bridge because abnormal bearing displacements could result from structural deterioration or damage. Therefore, an early warning method is established for ...
Damage Identification of Tie-Down Cables in Cable-Stayed Bridges Using Vehicle-Induced Displacement
Publisher: ASCE
Abstract: Tie-down cables are critical components of uplift-restraint bearings in bridges. Damage of a tie-down cable substantially affects the safety of a bridge and driving conditions. In this study, a damage identification method ...
