Based on the model test carried out by wave channel,the working conditions of fan support structure under water flow,cyclic load,waterless and still water environment were designed.The bearing performance of fan support structure under different load combinations such as unidirectional flow,cyclic load and the combination of unidirectional flow and cyclic load was obtained.The results show that the cumulative displacement of the fan support structure under the cyclic load is 46.12％of that under the static water condition,and the cumulative displacement of the support structure increa-ses by 60.84％under the combined action of one-way flow and cyclic load.Under the combined ac-tion of water environment and various loads,the bearing capacity of fan support structure is obviously reduced.Therefore,the influence of multiple loads should be considered in the structural design and safety evaluation of offshore wind turbines.
