The purpose is to provide a design reference for the preliminary wind resistance study of the cable-stayed bridge. The CFD (Computational Fluid Dynamics) numerical calculation method is used to solve the vibration problem of wind-bridge coupling with the help of the software Fluent. It is found that variation of four deck cross slope rates 0%, 1.5%, 2%, and 2.5% has large effects on the static wind coefficient and flutter critical wind speed of a \u03c0-type combination beam. In the range of a \u22123\u20133\u00b0 wind attack angle, the static wind drag coefficient will be decreased as the beam deck cross slope rate increases, and in which the drag coefficient at 0% slope rate is the largest. Within the discounted wind speed 13, changing the bridge deck cross slope has little effect on the aerodynamic derivatives of a \u03c0-type composite beam. However, the beam deck slope increases the critical wind speed of the bridge, and the critical wind speed at 2.5% is the largest of the four deck slope rates. In addition, it is found that the beam leeward surface keeps generating up and down vortices when the incoming flow wind speed is in the range of 2.5\u20134.0 m\/s, which led the beam to be under vertical vortex vibration, and further research is needed on vibration suppression measures.<\/jats:p>","DOI":"10.3390\/sym15040857","type":"journal-article","created":{"date-parts":[[2023,4,4]],"date-time":"2023-04-04T02:30:15Z","timestamp":1680575415000},"page":"857","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Numerical Simulation Research Considering the Influence of Bridge Deck Cross Slope on Wind Performance of \u03c0-Type Composite Beam Cable-Stayed Bridge with a Symmetric Elevation Arrangement"],"prefix":"10.3390","volume":"15","author":[{"given":"Shuaihui","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Transportation and Logistics Engineering, Wuhan University of Technology, Wuhan 430063, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5439-2626","authenticated-orcid":false,"given":"Xiangyang","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Transportation and Logistics Engineering, Wuhan University of Technology, Wuhan 430063, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"227","DOI":"10.1016\/j.jweia.2017.12.007","article-title":"Nonlinear post-flutter behavior and self-excited force model of a twin-side-girder bridge deck","volume":"177","author":"Gao","year":"2018","journal-title":"J.
