SEISMIC STUDIES OF THE ARTICULATION FOR THE DUMBARTON BRIDGE REPLACEMENT STRUCTURE. VOLUME 2. NUMERICAL STUDIES OF STEEL AND CONCRETE GIRDER ALTERNATES

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 2 considers the following topics: Numerical results for the effects of longtiudinal and vertical ground motions; and Numerical results for the effects of transverse ground motions.
