Abstract

The bearing characteristics of reduced diameter monopile of offshore wind power was researched in this paper using the finite element software. The numerical results show that the reduced diameter monopile has greater vertical bearing capacity than that of the conventional monopile. It can be seen from the equivalent plastic strain map that the vertical load mode of the reduced diameter monopile changes to the joint load mode of the end and the reducing section, compared to the end load mode of the conventional monopile. The height and diameter of the reducing section have a significant influence on the bearing capacity. Through the calculation of the proportion of each section of vertical bearing capacity, the outside of the reduced section bears the main vertical load, about 65%.

Key words
