| Abstract: |
| Air-supported structures are typical flexible structures,which are sensitive to wind.Wind loads are often crucial to structural design.The workbench platform in ANSYS14.5 program was used to investigate the wind pressure coefficient distribution of rectangular plane air-support structure considering fluid-structure coupling effect.RNG k-ε turbulent model based on Reynolds averaged N-S equation was used to simulate the wind field while the weak coupling method was adapted to investigate the coupling effect.The rise-span ratio of 1/4,1/2,1/3 and length-width ratio of 5/3,2/1,3/1 were adopted to calculate the structural response under different inner pressure and wind direction angles.Results show that the coefficient of wind pressure on structure considering fluid-structure coupling effect differs significantly from that without considering fluid-structure coupling effect and the impact index is between 1.25~1.5.The wind pressure coefficient distribution of structure is influenced by the wind angle,inner pressure,length-width ratio and other factors such as the rise-span ratio. |
