Dam Contraction Joint

Dam Contraction Joint

Dam Contraction Joint

(OP)
Hi all,
I am working on the structural design of a concrete gravity dam. The spillway is 56 meters wide. Three radial gates openings (12m wide x 15m high) are made for the spillway water leaving behind 6.4 meter thick piers. Contraction joints are placed in each pier for the entire 55m height of the dam leaving 3.2m wide pier on each side of the gate opening. The contraction joints are fully grouted.
The dam is in high seismic zone. OBE is 0.34 g and MCE is 1.16g. I am conducting the structural analysis by modeling 3.2m pier on each side of the 12m spillway opening. The structural design of spillway piers result in very high level of reinforcement in the piers.
My question is that "Is there any reference that I can assume some restraint at the grouted contraction joints to reduce the efforts in the piers?"
