Abstract
A wind turbine blade has upper and lower shell members with a respective spar cap configured on an internal face of the shell members. A shear web extends between the spar caps along a longitudinal length of the blade. A connection assembly is configured between the transverse ends of the shear web and the spar caps and includes a channel structure configured on the spar cap. The channel structure includes side walls that extend from the spar cap along the longitudinal sides of the shear web. A pliant actuation line is attached between the side walls of the channel structure and bond paste is deposited in the channel structure. Movement of the transverse end of the shear web into the channel structure results in the actuation line pulling the side walls of the channel structure against the longitudinal sides of the shear web.
