The end column horizontal movements at the initial backfill stage and the last
expansion cycle are presented in Fig. B.42 and B.43, respectively.
The results show that the effects of temperature on the deflection of the free
end of the single and 3-bay frames are nearly negligible, but said effects become
more pronounced for the remaining frames.
The horizontal deflection of the end column 10-bay frame, for instance, found
at the end of the last expansion cycle is larger by nearly 20% than its counterpart
found at the end of the initial backfill cycle, while the horizontal deflection of the
free end of the 20-bay frame at the end of the last expansion cycle is more than 1.5
times its counterpart found at the initial backfill stage.
