Abstract_FL Taking an actual flexible photovoltaic support as the research object,for which a finite element model was established.The accuracy of the model was validated by measuring the dynamic characteristics of the structure.Utilizing the dimension-reduction spectra representation method,a representative set of random wind speed samples within the entire probability space was generated.On this basis,in conjunction with the probability density evolution theory,the effects of basic wind speed,wind load direction,and pre-tension force in the supporting cables on its displacement response and wind-resistance reliability were studied.The re-sults indicate that as the wind speed increases,the wind-resistance reliability of the flexible photovoltaic sup-port structure decreases.When the basic wind speed reaches 25 m/s,the average overall wind-resistance relia-bility of the structure is only 0.14.Increasing the pre-tension force in the supporting cables significantly en-hances the wind-resistance reliability of the structure.However,as the pre-tension force increases,its impact on improving wind-resistance reliability diminishes.When the flexible photovoltaic support structure is subjec-ted to windward loads,it exhibits lower wind-resistance reliability compared to leeward loads.The effect of pre-tension force on improving wind-resistance performance is more pronounced in this scenario.
