Session 01: Case Histories of Unexpected Behavior and Failure of Shallow, Deep and Other Foundations
Location
Arlington, Virginia
Date
13 Aug 2008, 5:15pm - 6:45pm
Abstract
The paper studies the effect of large slope movements on foundations through case histories. More than 30 well-documented case histories of damaged buildings near the tip of slopes due to excessive movement caused by either heavy rain or earthquakes were collected. The case histories showed that a critical factor affecting the level of damage of buildings, is the coefficient Ι, that is defined as the ratio of the width below the foundation that settles by the total width of the foundation: (a) When Ι < 0.2, collapse does not occur, even if settlement is very large, (b). When 0.2 < Ι < 1.0, the level of damage depends both on settlement and the factor l. (c) When Ι=1, buildings may not collapse, even if the settlement is very large, about 1m, but damage and rotation may be high. The above hold regardless of the cause of the slide: heavy rain or earthquake.
