Dynamic response of train in wind-train-bridge coupling based on bridges with different structural systems

Abstract

Most studies have analyzed the aerodynamic characteristics and wind-train(vehicle)-bridge coupled vibration response of trains or vehicles on bridges of a certain structural system, while few comparative studies have been carried out on the wind-train-bridge coupled vibration response on bridges of three different structural systems. This paper takes the main span 1120 m dual-purpose highway-railway bridge as the engineering background, and studies the three bridge types of (122+1120+90+92) m suspension bridge, (130+432+1120+432+130) m cable-stayed bridge and (92+210+1120+210+92) m cable-stayed-suspension collaborative system bridge. The trend of the maximum value of the train dynamic response to the wind-train-bridge coupling of the three structural system bridges as well as the speed thresholds are compared and analyzed, and conclusions are drawn: 1) Under the same speed, the maximum value of train safety indexes in three types of bridges increases with the increase of wind speed. 2) Under the same wind speed, the safety and smoothness indicators of trains in three types of bridges without wind barriers rank in the order of cable-stayed-suspension collaborative system bridge>cable-stayed bridge>suspension bridge. 3) At low wind speeds (≤15 m/s), a 3.0 m wind barrier has negligible effect on speed thresholds. The safety ranking of structural systems remains unchanged: cable-stayed-suspension collaborative system bridge>cable-stayed bridge>suspension bridge. 4) At high wind speeds (≥20 m/s), the 3.0 m wind barrier can increase the train speed threshold for bridges within the same structural system. The safety ranking of the three bridge types (3.0 m 30% wind barrier) remains unchanged: cable-stayed-suspension collaborative system bridge>cable-stayed bridge>suspension bridge. This study represents the first systematic comparative analysis of wind speed critical values and performance ratings across three distinct bridge structural systems.
