Beschreibung
Zusammenfassung:	A rotor blade for a wind turbine includes first and second blade segments extending in opposite directions from a chord-wise joint. Each of the first and second blade segments includes at least one shell member defining an airfoil surface and an internal support structure. The internal support structure of the first blade segment includes a beam structure extending lengthwise, whereas the internal support structure of the second blade segment includes a receiving section that receives the beam structure of the first blade segment. Further, the rotor blade includes at least one chord-wise extending pin positioned through the beam structure and the receiving section at the chord-wise joint so as to secure the first and second blade segments together. The rotor blade includes at least one additional support member that receives a portion of the chord-wise extending pin so as to reduce a chord-wise bending deflection of the chord-wise extending pin at the chord-wise joint.
