Wind turbine foundation, is shown in Fig.1, consists of prime materials such as concrete, rebar and steel.
There are multiple connect forms between different materials inside of the wind turbine foundation.
To the contact problem of steel and concrete, many researches were done but the bind-slip effect between the two materials was ignored.
