RISTemperature Effects on Strain Influence Lines and Dynamic Load Factors in a Steel-Truss Arch Railway Bridge Using Adaptive FIR Filtering
Publisher: American Society of Civil Engineers
Abstract: The dynamic strain response due to the passing trains is one of the most important indexes in the design and maintenance of long-span steel-truss arch railway bridges. The strain influence line (IL) and dynamic load factor ...
Evaluation and Early Warning of Vortex-Induced Vibration of Existed Long-Span Suspension Bridge Using Multisource Monitoring Data
Publisher: ASCE
Abstract: Due to the designing characteristics of long span and low stiffness, the high-order vortex-induced vibration (VIV) of suspension bridges may occur under a special wind environment. The prototype monitoring data make it ...
Early Warning of Abnormal Train-Induced Vibrations for a Steel-Truss Arch Railway Bridge: Case Study
Publisher: American Society of Civil Engineers
Abstract: Considering the new challenges for high-speed railway bridges, the early warning of abnormal train-induced vibrations is necessary for ensuring the operation safety of both the bridge structures and the trains on the bridge. ...
Behavior Analysis and Early Warning of Girder Deflections of a Steel-Truss Arch Railway Bridge under the Effects of Temperature and Trains: Case Study
Publisher: American Society of Civil Engineers
Abstract: Complicated temperature fields and crossing high-speed trains offer new challenges for monitoring girder deflections in operating railway bridges. Behavior analyses and early warning of girder deflections are necessary for ...
Deep Learning-Based Minute-Scale Digital Prediction Model of Temperature-Induced Deflection of a Cable-Stayed Bridge: Case Study
Publisher: ASCE
Abstract: The evolution rule of temperature-induced deflection in main girders is an important index to evaluate the service performance of long-span cable-stayed bridges, which directly reflects the coupling effect between the ...
