Abstract
The paper outlines the recorded response to numerous earthquakes of the pile foundation, the supporting soil, and the superstructure of the main pier of a road bridge. The records include free-field accelerograms at the ground surface and the base of the alluvial deposit, accelerograms on the footing and the superstructure, and the bending and axial strain histories at several depths along two of the sixty-four piles. Recently developed methods of seismic analysis are used in interpreting the recorded data. Extensive comparisons are made between theory and measurements. Successes and failures of the theory are discussed. Emphasis is given to the distribution of seismic bending strains along the pile; the theoretically-anticipated concentration of such strains at an interface between two layers with sharply-differing soil stiffnesses is fully confirmed.

Seismic Response of the Pile Foundation of Ohba-Ohashi Bridge
St. Louis, Missouri
The paper outlines the recorded response to numerous earthquakes of the pile foundation, the supporting soil, and the superstructure of the main pier of a road bridge.

Recently developed methods of seismic analysis are used in interpreting the recorded data. Extensive comparisons are made between theory and measurements. Successes and failures of the theory are discussed.
