EFFECT OF UNEVEN THICKNESS OF SOFT GROUND ON EARTHQUAKE DAMAGE TO BUILDING

In order to clarify the structures of grounds, buildings on which are liable to be damages by earthquakes, many examples of their earthquake-induced damage have been investigated. The resluts are summarized as follows: 1) When grounds under buildings are hard, or when they are approximately horizontally-stratified though they are soft, the occurences of earthquake-induced damage to buildings are very rare; 2) buildings are liable to be deformed by earthquakes on grounds which are soft but inclined and when they straddle both soft and hard grounds. The deformation is liable to occur in the inclined direction of the soft ground bottom; 3) many buildings have been damaged by a large lateral or vertical differential displacement due to the uneven thickness of soft ground; 4) abovementioned soft grounds include layers like peaty soil, extremely soft clayey soil, liquefiably sandy soil, reclaimed soil or embankment; 5) shear cracks of buildings are liable to occur at right angles to the equi-depth line of soft ground bottom, and predominant shear crack line drops in the direction of soft ground becoming thin.
