Which version are you referring to? I have both versions
The earlier version defined the maximum wind speed, annual average wind speed and turbulence intensity
The latest The version removes the annual average wind speed and lowers the turbulence intensity
The maximum wind speeds in the 1, 2, and 3 wind areas are 50, 42.5, and 37.5 respectively. The turbulence intensity is divided into three levels: A, B, and C, which are 0.16, 0.14, and 0.12 respectively. There is an S-level wind zone whose parameters can be configured by yourself
