RISUncertainty Quantification in Stochastic Subspace Identification Using a Simulation Method with DBSCAN-Based Outlier Detection
Publisher: American Society of Civil Engineers
Abstract: AbstractThere are variance errors in the modal parameters estimated by stochastic subspace
identification (SSI), with specified model order and time lag parameter. To quantify
the variance of the identified modal parameters, ...
Effect of Temporary Barriers on the Vortex-Induced Vibration Performance of a Long-Span Bridge during Maintenance Periods
Publisher: American Society of Civil Engineers
Abstract: Abstract During maintenance of an in-service long-span bridge, temporary barriers (TBs) are
often employed on the deck for construction isolation, which will change the aerodynamic
profile of the bridge girder and potentially ...
Experimental Study on Train-Induced Longitudinal Movements and Control Measures for a Suspension Bridge Using a Scaled Model
Publisher: American Society of Civil Engineers
Abstract: Abstract This study investigates the longitudinal reciprocating movement of the stiffening
girder caused by trains passing over suspension bridges, which can adversely impact
expansion joints, bearings, dampers, and overall ...
