The objectives of this investigation are (1) to develop reliable and efficient techniques for analyzing the earthquake response of intake-outlet towers of arbitrary geometry but with two axes of plan symmetry, including tower-water interaction and tower-foundation-soil interaction; (2) to investigate the significance of these interaction effects on the earthquake response of towers; (3) to develop a simplified analysis procedure for the preliminary phase of design and safety evaluation of towers that provides sufficiently accurate estimates of the design forces directly from the earthquake design spectrum; and (4) to develop the necessary techniques, tables, and charts for convenient implementation of the simplified analysis procedure. The dynamic response of Briones Dam Intake Tower to Taft ground motion is presented for various cases: rigid or flexible foundation rock, and with or without water.
