Abstract
Wind load is one of the dominating loads for offshore wind measurement mast, whose applied amount relates closely to safety and economical efficiency.A traditional wind load model includes merely an isolated upper mast, and calculation is based on the standard of Load Code for the Design of Building Structures.To give a better simulation of wind load, a full-coupled model con-taining both the upper mast and lower foundation was built for numerical anslysis, then a comparison with code method was made.To deal with the close loop relationship between wind load and natural frequency, iteration was introduced to solve for wind vibration co-efficient.Through comparison, it was found that with identical input, wind load calculated by mumerical method is 6%~26%smal-ler than those from code method.关键词
