Assembly comprising a first and a second member and a connector, and a method of assembling such an assembly

A method of assembling a first and a second member of a wind turbine assembly, where the first and second members each comprise at least one through hole, wherein the second member has a fork-shaped cross section with a main body arranged between two parallel walls that each comprise at least one through hole, said method comprising:

• arranging the first member between the two walls of the second member;
• positioning the through holes of the first and the second member to define a channel;
• inserting a connector into the channel to an end position;
• and
• consecutively expanding said connector radially relative to said channel, to thereby connect the first and second member relative to each other,
• wherein the expanded connector pushes the first member in a radial direction relative to said channel against a face of the main body of the second member to define a clamping contact and thereby a pre-tensioned connection in a radial direction relative to said channel between a face of the first member and the face of the main body of the second member.
