Forced vibration and earthquake behaviour of an actual pile foundation
The dynamic properties of the pile foundation supporting the Imperial County Services Building in El Centro, California, USA, were determined by forced vibration testing. These test results are described in detail and are used to formulate a mathematical model of the foundation. The model is then employed in a study of the interaction between the foundation and building which occurred during the October 1979 earthquake. Differences between the ground motions recorded at the base of the building during the earthquake and those recorded at a free-field site are investigated. Some correlation is seen when these differences are compared to motions computed by applying the measured building base shear to the mathematical foundation model. The disturbances caused by the building at the free-field site is seen to be small.
