A turbine rotor blade (10) includes a hollow airfoil (12) joined to a platform (14) and dovetail (16). A main flow channel (6) extends longitudinally in span through the blade (10) and is bound chordally by opposite partitions (34) transversely bridging opposite sidewalls (20,22) of the airfoil (12). A damper rib (44) and transversely opposite damper pad (48) are arranged together in a plurality of pairs spaced longitudinally apart in the airfoil (12) and chordally positioned intermediate to the partitions (34) to provide unobstructed forward and aft portions of the flow channel (6) for channeling a coolant (32) therethrough. The damper ribs (44) and pads (48) are configured to receive a wire damper (42) through the channel (6) to locally dampen vibration while minimizing obstruction of the coolant flow (32) therethrough.
