Tóm tắt
In areas frequently affected by strong winds, high-speed railway (HSR) bridges are commonly equipped with wind barriers to ensure train operational safety. This study focuses on a multi-span simply supported prestressed concrete bridge located along a real HSR line in Western China. Different barrier configurations with varying heights and porosities are investigated. A comprehensive wind-train-bridge interaction dynamic model is established to simulate the system's response, incorporating the effects of fluctuating crosswind velocities. Temporal histories of dynamic responses from both the train and the bridge are calculated and analyzed. A comparative evaluation of various barrier designs is conducted to determine their effectiveness in mitigating adverse wind effects. The results indicate that a barrier with a total height of 3.5 meters, consisting of 10% porosity in the lower 1.0 meter and 20% porosity in the upper 2.5 meters, provides the best performance in balancing wind shielding and structural stability. This research offers valuable insights for optimizing the design of wind barriers on HSR bridges in high-wind regionsTài liệu tham khảo
