A Simulation of Non-Simultaneous Ice Crushing Force for Wind Turbine Towers with Large Slopes
When the offshore wind energy industry attempts to develop in cold regions, ice load becomes the main technological challenge for offshore wind turbine foundation design. Dynamic ice loads acting on wind turbine foundations should be calculated in a reasonable way. The scope of this study is to pres...
