Abstract: Joints for connecting a first blade segment to a second blade segment of a wind turbine rotor blade include a first bolt comprising a first proximal end connected to the first blade segment and a first distal end connected to the second blade segment, a second bolt comprising a second proximal end connected to the first blade segment and a second distal end connected to the second blade segment, and a third bolt comprising a third proximal end connected to the first blade segment and a third distal end connected to the third blade segment. At least two of the first bolt, the second bolt and the third bolt differ in size, and a first distance between the first bolt and the second bolt is different than a second distance between the second bolt and the third bolt.
