Seismic Microzonation Study at the Port of Oakland
This paper presents the findings of a microzonation study conducted at the Port of Oakland in northern California. A 150-meter-wide strip of land along the entire waterfront at the Port was divided into a number of site categories for which linear and nonlinear site response analyses were performed. The purpose of the microzonation study was to 1) establish a consistent set of design ground motions for use by consultants in dynamic analysis and seismic design of various Port facilities and 2) provide design guidelines for site response analysis of Port facilities that requires site-specific studies. As part of this study, more than 500 one-dimensional site response analyses were conducted using three computer programs: SHAKE, TESS, and FLAC. In addition, a limited number of two-dimensional analyses were conducted using QUARD4M and FLAC programs for one of the wharf structures. A comprehensive search for dynamic soil properties was conducted. The sensitivities of the results to the computational scheme (linear versus nonlinear), frequency contents of ground motion (fault normal versus fault parallel component), thickness of soft soils (Young Bay Mud), total thickness of soil deposits, and the two-dimensional geometry of the waterfront were studied and evaluated.
