NSF: Use of two shake tables for the evaluation of the seismic performance of piping distribution systems subjected to independent floor motions, PI: MaragakisS f• Shared-use status, funded by MCEER/NSF

• Original testing plan required the use of t h k t bltwo shake tables

• Deviated from the original test plan

• The modified plan required• The modified plan required mounting a sliding platen on top of the frame attached to an actuator, which requiredwhich requiredsynchronization with the shake table
