elevation survey measurements were made.
The maximum piiier heave measured at that time was 280 mm (11 in.).
Most of the building movement occurred in the west half of the building, particularly in
the southwest corner.
The differential movements along with the dips of the beedrock caused large lateral forces to be applied to the piiiiers.
Some of the piiiiers had undergone large heave and experienced shear failure. Fig. 5 shows shear failure of a pier at the site
in January 1998.
