The analysis was also very consistent for the records of the drifts for the middle orthostate during excitations and the respective records for the backing wall. In all records was obvious that the freestanding orthostate (Ø0) preformed a rocking motion around its base, as can be seen in Fig. 9 by the large spikes around 0 of the respective diagram. The positive drift values correspond to the West. The backing wall, on the other hand, tends to slowly slide towards the east for the case of the freestanding orthostate, as can be seen in Fig. 10. In all other cases, where connections were provided between the two facades of the pediment, the drifts were minimized and the two facades behaved in conformity in a very restricted rocking motion. The analysis also provided the design force for the special connectors equal to approximately 7 tons.
