and column are found to progressively displace away from the retained soil with
every full cycle of temperature change. The retaining wall movements indicate a
larger increase in displacement at the end of each temperature cycle compared to
the end column. This is in-line with the field measurements presented in Fig. 4.23.
The total change in displacement for the retaining wall at the top of the structure is
approximately 0.0756 ft (2.3 mm) between the second and fourth temperature
cycle, almost equal to the change in displacement obtained from field
measurements. Moreover, the range of movements of the retaining wall with
temperature cycles is smaller than its counterpart for the end column, which is also
found the monitoring of the actual structure. Overall, the general displacement
behavior of the rigid frame extremities, as well as the magnitude of said
displacement, is in agreement with the measured movements obtained in the field
and presented in Chapter 4.
The bending moments in the retaining wall and end column found from the
analysis are shown is Fig. 6.10 below.
