چکیده
In this work, a monorail vehicle-bridge coupling (VBC) model capable of accurately considering curve alignment and superelevation is established based on curvilinear moving coordinate system, to study the VBC vibration straddle curved girder bridge relevant factors influencing VBC. While taking Chongqing Jiao Xin line as an example, program compiled using Fortran, where reliability algorithm verified by results test. Moreover, effects radius, vehicle speed, track irregularity corresponding vibrations are compared analyzed. It observed that test lateral acceleration (LVA) vertical (VVA) beam, LVA vehicle, consistent with simulation results. Owing irregularity, beam increases significantly. Besides, increase in speed gradually vehicle. For radius (R) ≤ 200 m, decrease significantly increasing radius. Alternatively, when m

Load Test and Model Calibration of a Horizontally Curved Steel Box-Girder Bridge
In this paper, full scale load test of a horizontally curved steel box-girder bridge is carried out in order to detect structural defects, which reportedly result in unwanted vibrations in nearby buildings. The bridge is tested under the passage of six heavy vehicles at different speeds, so as to determine its static and dynamic responses. A total number of one hundred and two (102) sensors are...

متن کاملLamb Wave Behavior in Bridge Girder Geometries
Lamb waves in plates and in cylindrical pipes have been the subject of extensive study, largely because they propagate great distances with little attenuation, and can therefore be used to detect flaws. In this paper we report finite element simulations and experimental studies of Lamb waves in steel bridge girder geometries. In our studies the Lamb waves are generated by PZT wafer-type transdu...
