Abstract
After the initial full loading of two similar grain silos, which were built on silty sand, the Export-Import Building tilted toward the Working Tower and the joints between the two structures closed. The lateral force caused cracks in the columns of E-I Buildings. Two different methods were used to rotate the structure. The first method was based on the uneven loading of structures. The second method vas to remove thin layers of soil by chains under the foundations. The B-I Buildings were successfully rotated at both sites in 1989. The measurements for settlement and tilt were made to compare the performance of the structures after the imposed rotation. The comparisons of results show that the tilting of structures by the second method is preferable to the first method. This is due to the fact that in removing thin layers of soil the change in stress distribution is minimized.

The Performance of Structures After Imposed Rotations
St. Louis, Missouri
After the initial full loading of two similar grain silos, which were built on silty sand, the Export-Import Building tilted toward the Working Tower and the joints between the two structures closed.
