Abstract: A jointed wind turbine rotor blade includes a first blade segment and a second blade segment extending in opposite directions from a chord-wise joint. A beam structure extends span-wise from the first blade segment into a receiving section formed in the second blade segment. The receiving section includes opposite spar caps and opposite interconnecting webs. The spar caps have a constant thickness along the receiving section where the spar caps overlap with the beam structure and are formed of a material or combination of materials along the receiving section to produce a desired stiffness of the spar caps along the receiving section. The webs have a reduced amount of conductive material adjacent to a chord-wise joint between the blade segments.
