The horizontal movements of the retaining wall portion of the three story RFERS
with a bay length of 20 feet and column to beam stiffness ratio of 4 are presented
in Fig. 9.29 and 9.30 for the initial backfill stage and the last expansion cycle
respectively. Only the 3 and 10-bay frames are presented given that the single bay
analysis could not be completed due to failure of the soil mass during the
numerical simulation.
