Seismic Studies of the Articulation for the Dumbarton Bridge Replacement Structure. Volume 1. Description, Theory, and Analytical Modeling of Bridge and Components
The influences of various girder types and joint articulations on the seismic responses of long multi-span highway bridges are reported. The girder types are of cast-in-place and precast concrete constructions and steel twin-box sections. Various types of expansion joints and girder to pier-cap connections are considered. A 7400 feet long bridge, that is to cross the lower arm of San Francisco Bay, is studied. The bridge is composed of 43 spans founded on various soil conditions, including Thick-Mud and Deep-Water sections. Response characteristics are determined for light, moderate, and severe ground motions of both sections. Time-history and spectral analyses based on design and response spectra are performed for two- and three-dimensional models. Interactions of water mass, soils, footings, and piling groups are considered. Volume 1 considers the following topics: Description of two alternate designs for the Dumbarton Bridge structure and the selection of the final design for the structure over the thick mud sections; Soil investigations, design spectra, and corresponding ground surface motions; Analytical models.
