A limited seismic investigation of Ball Mountain Dam, an earthen dam near Jamaica, Vermont, was conducted using multiple seismic methods including multi-channel analysis of surface waves (MASW), refraction tomography, and vertical seismic profiling (VSP). The refraction and MASW data were efficiently collected in one survey using a towed land streamer containing vertical-displacement geophones ...

Abstract—In this paper, a one-dimensional (1d) Parallel ElastoPlastic Model (PEPM), able to simulate the uniaxial dynamic behavior of seismic isolators having a continuously decreasing tangent stiffness with increasing displacement, is presented. The parallel modeling concept is applied to discretize the continuously decreasing tangent stiffness function, thus allowing to simulate the dynamic b...

Soil-structure interaction (SSI) could affect the seismic response of structures. Since liquid storage tanks are vital structures and must continue their operation under severe earthquakes, their seismic behavior should be studied. Accordingly, the seismic response of two types of steel liquid storage tanks (namely, broad and slender, with aspect ratios of height to radius equal to 0.6 and 1.85...

This study is devoted towards evaluating seismic performance of a three-span continuous highway bridge subjected to moderate to strong earthquake ground motions in its longitudinal direction. In this regard, nonlinear dynamic analysis of the bridge based on the direct time integration approach using the 4 order Runge-Kutta method is conducted. Two types of isolation bearings are used in the ana...

Fractures play an important role in most carbonate and unconventional reservoirs. Precise identification of fractures and their associated properties from seismic data have significant impact on reservoir management and hydrocarbon recovery. Traditional seismic methods for fracture identification and characterization, such as shear birefringence and amplitude variations with offset and azimuth,...

Reservoir engineers have to predict the behavior of a hydrocarbon reservoir by building a simulation model which can reproduce as best as possible the data collected on the field. These data fall into two types: static data, which are invariable in time, and dynamic data, which evolve according to fluid motions in the reservoir. In this paper, we focus on the integration of dynamic data related...

Presented here is an analysis of the effects of soil-foundation-structure interaction (SFSI) on seismic response of highway bridges. Of particular importance is the issue of input motions, their scaling and application to the SFS models. The analysis presented in this paper addresses the influence of inelastic behavior of both the soil and the structural components during seismic response evalu...

Introduction The description of a fault model includes the fault surfaces and associated tip lines, the fault network geometry, and the displacement geometry of faults. Fault surfaces are usually observed from seismic discontinuities, which include reflector breaks, flexures, and amplitude changes. These discontinuities can often have a regular appearance that corresponds to fault geometries fo...
