Influence of Barrier Shapes on Flutter Instability of a Streamlined Steel Box Girder
https://orcid.org/http://orcid.org/0000-0002-8108-5522
This paper aims to focus on the flutter instability analysis of a streamlined steel box girder and investigate the influence of the barrier shape on this type of wind-induced instability of the girder. In particular, the steel box girder of the Thuan Phuoc suspension bridge in Da Nang city is selected as a case study. Based on a computational wind engineering approach, aerodynamic flutter derivatives of the girder cross-section are identified that allow calculating the critical flutter wind speed of the girder section. The results are then validated with experimental data available from the literature. Finally, a study on the influence of the barrier shape on flutter instability of the girder cross-section is presented considering three different barrier shapes, i.e., solid rectangular, porous rectangular, and curved shapes. Based on the analysis results, the optimal barrier shape respectively for each type is recommended to increase the aerodynamic stability of the examined box girder.
