Abstract: Taking the cantilevered string structure of a stadium in Pujiang as a research object, the wind vibration response and equivalent static wind load of the structure based on wind tunnel test data were discussed. A finite element model considering the cable's geometric non-linear characteristics was established, and the wind speed time-history of the test points was equivalent to the load time-history of the finite element node by interpolation method, and the wind vibration response extraction was performed. The conclusions are as follows:the combination of wind load time-history and other loads would make the structural design process complicated, and then the load wind vibration coefficient was introduced to establish the relationship between the dynamic response of the structure and the static wind pressure, and it was converted into an equivalent static wind load. Meanwhile, based on the equivalent static wind load, a geometric nonlinear analysis of the cantilevered string structure was carried out. There were obvious differences in wind vibration coefficients at different locations of the canopy, and it was advisable to adopt a multi-partition wind vibration coefficient under 0°~180° wind angle when carrying out structural design to ensure safety and economy.
