Abstract

Abstract

The characteristics of wind pressure distribution of an ellipsoidal air-supported structure considering fluid-structure interaction and fluctuating wind effect were studied. Firstly, the time-history data of fluctuating wind speed obtained in MATLAB by using linear filter method was imported into Fluent. Secondly, the wind pressure coefficients of the structures under different wind direction angles, heights and internal pressures after the wind-induced response stabilized were obtained by the partitioned weakly coupled algorithm on Workbench 17.0 platform. The results showed that the extreme values of the negative pressure coefficient increased obviously when the fluid-structure interaction was considered. The three variables had influence on the distribution, magnitude and changing rate of wind pressure. The wind pressure extreme values of the structure could be kept at a low level at 400 Pa.
