Long-period Ground Motion from a Great Earthquake
Direct body waves and fundamental surface waves are calculated for a credible, hypothetical great earthquake on the San Andreas Fault. The prototype event assumed is the Fort Tejon earthquake of January 9, 1857. Amplitudes and durations of long-period ground motion ( T > 1 sec) are found for a receiver in downtown Los Angeles. Calculations are carried out for various epicenters, dislocation pro...
متن کاملTilts in Strong Ground Motion
Most instruments used in seismological practice to record ground motion are pendulum seismographs, velocigraphs, or accelerographs. In most cases it is assumed that seismic instruments are only sensitive to the translational motion of the instrument’s base. In this study the full equation of pendulum motion, including the inputs of rotations and tilts, is considered. It is shown that tilting th...
متن کاملPROPERTIES OF STRONG GROUND MOTION EARTHQUAKES* By
THE USUAL type of California earthquake is associated with a relative horizontal slipping of the two faces of a fault which lies essentially in a vertical plane. As a consequence of this slipping, the surface of the ground experiences a severe motion in the neighborhood of the fault during large earthquakes. This surface ground motion can be measured, and for the relatively small number of stro...
متن کاملVariations of Strong Earthquake Ground Motion In
Accelerograms recorded at six stations in the metropolitan Los Angeles area during the Borrego Mountain, 1968, the Lytle Creek, 1970, and the San Fernando, 1971, earthquakes in southern California have been studied. In comparing the ground motions recorded during different earthquakes at each of the six stations and in correlations of these motions recorded at different stations during the same...
متن کاملNonlinear Dynamic Analysis of Pile Foundation Subjected to Strong Ground Motion Using Fiber Elements
In this paper, pile behavior embedded in layered soil deposits subjected to seismic loadings is analyzed using a nonlinear fiber element for simulation of soil – pile interactions. In the created model, both pile and surrounding soil are modeled using fiber elements in a practical Beam on Nonlinear Winkler Foundation (BNWF) concept. Herein, the features of DRAIN–3DX finite element software are ...
