Under the support structure system of air cooled condenser there are large-diameter group columns, the proposed wind parameters in present load code can't be used directly in the wind resistance design of this kind of structure. A rigid model with 1:150 scaling factor was made, and wind tunnel test was carried out to study the wind pressure distribution on the large-diameter columns. In order to obtain the body coefficient of the large-diameter column, FLUENT 6.1 software was used to simulate the wind field of the structure. Wind tunnel test for wind pressure distribution on pipe column surface and test data processing were presented in detail. The feasibility of CFD numerical simulation in wind resistance design of structure was verified by comparing the results of wind tunnel test with those of the simulation.
