Title: Study of Coupling Vibration of Wind-vehicle-bridge System for Inclined Single Pylon Cable-stayed Bridge with Hybrid Girder
Abstract: A wind load formula for road vehicle which is distinct for the feature of three-dimensional flow was derived based on the quasi-steady theory.Taking natural wind,road vehicle and bridge as unified interaction system,an improved coupling vibration analysis model of wind-vehicle-bridge system was established.In the case study,an inclined single pylon cable-stayed bridge with hybrid girder was explored to investigate the coupling vibration characteristics of vehicle-bridge system under cross wind.Results show that vertical vibration is dominant over transverse vibration for the bridge while transverse vibration is more obvious than vertical vibration for the vehicles due to different aerodynamic characteristics of vehicle and bridge.
