Abstract

The invention is applicable to the technical field of bridge design, and discloses a method, system and terminal device for determining the aerodynamic resistance of a stay cable. The method comprisesthe following steps: obtaining the size information of the stay cable and the environmental information of the stay cable; determine the Reynolds number of stay cables according to the size information and environment information; the turbulence degree of stay cables is obtained and the fitting parameters are determined according to the turbulence degree. The resistance coefficient of stay cableis calculated according to the fitting parameters and Reynolds number. The aerodynamic drag of stay cables is calculated according to the drag coefficient, dimension information and environment information of stay cables. The invention can solve the problem that the calculation result is inaccurate due to the calculation of the aerodynamic resistance of the stay cables according to the lower turbulence degree in the prior art, can accurately calculate the aerodynamic resistance of the stay cables under the actual turbulence degree, and has important significance for the accuracy and scientificity of the structural design of the cable-stayed bridge.

Description

technical field [0001] The invention belongs to the technical field of bridge design, and in particular relates to a method, system and terminal equipment for determining the aerodynamic resistance of a stay cable. Background technique [0002] Cable-stayed cables are one of the main stress-bearing components of cable-stayed bridges. Accurately grasping the aerodynamic resistance on cable-stayed cables is of great significance for the stability check, vibration analysis and vibration control design of the bridge. [0003] At present, the premise of calculating the aerodynamic resistance of the stay cable is that the turbulence degree of the wind field is less than 1%. This leads to inaccurate calculation results of the aerodynamic resistance of the stay cables. Contents of the invention [0004] In view of this, the embodiments of the present invention provide a method, system and terminal equipment for determining the aerodynamic resistance of a stay cable, so as to solv...
