The Earthquake Engineering Online ArchiveSeismic studies of the articulation for the Dumbarton Bridge replacement structure, Vol. 2: Numerical studies of steel and concrete girder alternatesBaron, Frank; Hamati, Raymond E. UCB/EERC-75/09, Earthquake Engineering Research Center, University of California, Berkeley, 1975-02, 141 pages (630/B3/1975/v.2) This volume continues the study on the influences of various girder types and joint articulations on the seismic responses of long multispan highway bridges begun in Volume 1 ("Seismic studies of the articulation for the Dumbarton Bridge replacement structure, Vol. 1: Description, theory, and analytical modeling of bridge and components," by Baron and Hamati, Feb. 1975, UCB/EERC-75/08). Response characteristics are determined for light, moderate and severe ground motions of both the thick mud and deep water sections on which the Dumbarton Bridge replacement structure is founded. 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. Available online: http://nisee.berkeley.edu/documents/EERC/EERC-75-09.pdf (12 MB) |
