RISStructural Identification Using Computer Vision–Based Bridge Health Monitoring
Publisher: American Society of Civil Engineers
Abstract: This paper presents a new structural identification (St-Id) framework along with a damage indicator, displacement unit influence surface using computer vision–based measurements for bridge health monitoring. Unit influence ...
Ambient Vibration Data Analysis for Structural Identification and Global Condition Assessment
Publisher: American Society of Civil Engineers
Abstract: System identification is an area which deals with developing mathematical models to characterize the input-output behavior of an unknown system by means of experimental data. Structural health monitoring (SHM) provides the ...
Damage Assessment with Ambient Vibration Data Using a Novel Time Series Analysis Methodology
Publisher: American Society of Civil Engineers
Abstract: In this study, a novel approach using a modified time series analysis methodology is used to detect and locate structural changes by using ambient vibration data. In addition, it is shown that the level of the damage feature ...
Condition and Damage Assessment: Issues and Some Promising Indices
