Abstract

Various characteristics of ground motions from earthquakes are discussed. Ground motion recordings from recent earthquakes confirm that near-fault ground motions fare different from ordinary ground motion in that they often contain strong coherent dynamic long period pulse and permanent ground displacements. The permanent ground displacement in near-fault ground motions are caused by the relative movement of the two sides of the fault on which the earthquake occurs. The permanent ground displacements occurs at about the same time as the large dynamic motions, indicating that the permanent and dynamic displacements need to be treated as coincident loads.
