Abstract:
Based on the engineering background of a two parallel long-span Π-shaped girder cable-stayed bridge, the 1:25 scale segmental model wind tunnel tests were conducted to investigate the aerodynamic interference effects between an existing bridge(old bridge)and its adjacent newly constructed bridge(new bridge). The vortex-induced vibration(VIV)responses of main girders of the new bridge, old bridge, and the two parallel bridge were tested under a wind attack angle of -3°. Addressing the issues of the vertical VIV amplitude exceeding the code limit for the new bridge and the significant torsional vibration for the old bridge during the two parallel bridge tests, four aerodynamic measures, including enclosing pedestrian railings, installing guide vanes, flow suppression plates and lower stabilizing plates, as well as their combinations, were employed to optimize the VIV properties of main girders. The computational fluid dynamics(CFD)numerical simulations were utilized to analyze the flow field distributions around the main girder sections for both the original and modified schemes of the new and old bridges. The vibration suppression mechanisms during the aerodynamic optimization test were revealed. The research results indicate that the new bridge exhibits significant VIV with the maximum amplitudes exceeding the code requirements, while the old bridge shows negligible VIV phenomena. During the two parallel bridge tests, when the new bridge is at the upstream of the airflow, adverse aerodynamic interference occurs from the new bridge to the old bridge, causing noticeable VIV in both structures. When the old bridge is at the upstream of the airflow, its inherent satisfactory VIV properties combined with shielding effects on the new bridge prevent VIV occurrence in both girders. Single aerodynamic measures provide limited VIV suppression for the new bridge, whereas a combined solution of two 2.2 m-high lower stabilizing plates combined with flow suppression plates on the outer anti-collision guardrail effectively controls VIV amplitudes within 20% of the code limits for both bridges. The combination measure disrupts the formation of regular vortex shedding patterns near the girder bottom and bridge deck railings, improves the flow field distributions around main girders of both the new and old bridges, and significantly enhances the VIV properties of the two parallel bridge.3 tabs, 18 figs, 30 refs.
