Abstract: Hinge joint damage is the main defect that affects the safety of assembled hollow slab bridges. There are some studies on vibration-based damage detection for hinge joints. However, the effect of hinge damage on the modal ...

Abstract: Hinge joint damage is the main defect affecting the safety of assembled hollow slab bridges. The timely discovery of hinge joint damage is significant for guaranteeing the structural safety of assembled hollow slab bridges. ...

Abstract: Flexibility plays an important role in bridge load-carrying capacity assessment. The flexibility of bridges has been extracted from the measured data of numerical impact testing and in laboratory experiments. Recently, ...

Abstract: During long-term bridge monitoring, model updating is necessary because it provides the basis for accurate condition assessment and damage detection. In this study, an adaptive sampling-based Bayesian model updating method ...

Abstract: Structural modal identification for providing dynamic properties, including frequencies, damping ratios, and mode shapes, plays an important role in structural health monitoring and safety assessment. Automated modal ...

Abstract: Structural health monitoring of bridges based on train-induced vibrations has attracted extensive attention and takes advantage of the high-magnitude and regularly spaced features of trainloads. However, the monitoring ...

Abstract: Stay cables are vital load-bearing components of cable-stayed bridges that are prone to corrosion and fatigue. Damaged or deteriorated cables can endanger the safety of bridges. In this paper, a performance alarming method ...

Abstract: The deflection of a bridge under a dominant load, called key deflection is an important parameter that reflects the load-bearing capacity of in-service bridges. The impact vibration test is a good candidate for obtaining ...

Abstract: Stay cables are crucial components in cable-stayed bridges. The time-varying cable tension is an important indicator for the condition assessment of cables because the variation in tension will cause fatigue damage. This ...

Abstract: To achieve a high-efficiency impact test for deck flexibility identification of bridges, a reference-free substructuring test strategy with a two-stage integration method is proposed, which can be adopted to integrate the ...
