This report is the third in a series that deals with the design of the Dumbarton Bridge replacement structure for resisting seismic disturbances. The replacement structure is a long multispan bridge which will be located approximately equidistant (ten miles) from the San Andreas and Hayward faults. In the report, particular reference is made to a final selection of the girder types and the articulation of the replacement structure. The final design is analyzed for various ground motions, including ground surface motions which propagate along, oblique, and transverse to the longitudinal axis of the bridge. This third and final phase of the investigation deals with the influences of spatial distributions of ground motion of the maximum values of response of the replacement structure.
