Stochastic Finite-Fault Modeling of Ground Motions from the 1994 Northridge, California, Earthquake. II. Widespread Nonlinear Response at Soil Sites
On average, soil sites behaved nonlinearly during the M 6.7 1994 Northridge, California, earthquake. This conclusion follows from an analysis that combines elements of two independent lines of investigation. First, we apply the stochastic finite-fault simulation method, calibrated with 28 rock-site recordings of the Northridge mainshock, to the simulation of the input motions to the soil sites ...
متن کاملStochastic Finite-Fault Modeling of Ground Motions from the 1994 Northridge, California, Earthquake. I. Validation on Rock Sites
The stochastic method of simulating ground motions from finite faults is validated against strong-motion data from the M 6.7 1994 Northridge, California, earthquake. The finite-fault plane is subdivided into elements, each element is assigned a stochastic o92 spectrum, and the delayed contributions from all subfaults are summed in the time domain. Simulated horizontal acceleration time historie...
متن کاملWavelet-based Analysis for Pulse Period of Earthquake Ground-motions
Pulse period of earthquake records has been known as a key parameter in seismology and earthquake engineering. This paper presents a detailed characterization of this parameter for a special class of earthquake records called pulse-like ground motions. This type of motions often resulting from directivity effects is characterized by a strong pulse in the velocity time history of motion, in norm...
متن کاملStochastic Modeling of Macromolecular Motions through Post Arrays
The dynamic motions of macromolecules through a microfluidic postarray system are simulated using a threedimensional stochastic finite element approach. The effects of molecular conformation on the time for a macromolecule to move across the system are investigated. The analyses are first performed on disklike geometries and then extended to a representative carbonic anhydrase (CA) macromolecul...
متن کاملSimulation of Strong Ground Motions
The estimation of potential strong ground motions at short epicentral distances (J1 = 10 to 25 km) resulting from large earthquakes, M;;;; 6.5, generally requires extrapolation of a limited data set. The goal of this project has been to quantify the extrapolation through a simulation technique that relies heavily upon the more extensive data set from smaller magnitude earthquakes. The simulatio...
