Stochastic analysis of seismic ground response for site classification methods verification
Soil Dynamics and Earthquake Engineering, 2018Abstract A database of numerical ground response analyses has been generated to assess the effectiveness of site classification schemes adopted in seismic building codes. 1-D Ground models have been generated with a stochastic approach based on a Monte Carlo procedure and the corresponding seismic response has been evaluated by the equivalent linear ...

Ground motion selection for seismic response analysis
2017This dissertation addresses several fundamental and applied aspects of ground motion selection for seismic response analyses. In particular, the following topics are addressed: the theory and application of ground motion selection for scenario earthquake ruptures; the consideration of causal parameter bounds in ground motion selection; ground motion ...

Seismic Ground Strain Simulations for Pipeline Response Analysis
1991The analysis and design of buried pipelines to resist seismic ground motions relies on estimates of the seismic ground strains. It is generally assumed that estimates of the maximum axial strain along the pipeline can be determined from the ratio of the maximum velocity recorded at the site over the velocity of the apparent propagation of the motions ...

Ground seismic response analysis based on the probability density evolution method
Engineering Geology, 2015Abstract Based on an overview of pertinent literature, the work presented in this paper focuses on the simulation of non-stationary ground motion processes and the stochastic seismic response analysis of site-specific soils. Using the random process orthogonal expansion method and the concept of random functions, initial earthquake ground motion is ...

Analysis of Seismic Responses During Near-Source Ground Motions
Advanced Materials Research, 2012Seismic responses can strongly determine damages of bridge structures, e.g. due to pounding and unseating of girders as observed in many major earthquakes in the past. In the investigations often uniform ground excitation and pounding at only one location are considered.

Seismic response analysis of earth dams under differential ground motion
Bulletin of the Seismological Society of America, 1987Abstract The effects of amplitude and phase difference of an earthquake motion on the seismic response of long earth dams were studied. The dam was modeled as a two-dimensional shear beam whereas the seismic input, applied at the base of the dam, assumed various forms to reflect the variation of amplitude and phase of the ground motion ...

Seismic Analysis of Ground-Supported Tanks Using the Vertical Response Spectrum
Geotechnical and Structural Engineering Congress 2016, 2016Vertical ground motions can have a significant impact on the structures vertical response for several types of nonbuilding structures. Tanks and vessels, hanging structures, and horizontal cantilever systems are some examples. The forthcoming American Society of Civil Engineers (ASCE) 7-16 code requirements for vertical response spectrum will now ...

Soil Dynamics and Earthquake Engineering, 2015
Abstract Small-strain stiffness and damping ratio are the key parameters for modeling the dynamic behavior of soils, but they are often problematic and onerous to obtain under field conditions. This is particularly true for the attenuation characteristics.

SEISMIC RESPONSE ANALYSIS OF CONTINUOUS HIGHWAY BRIDGES UNDER NEAR-FAULT GROUND MOTIONS
Proceedings of the 6th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2015), 2017Ground motions in proximity to the causative fault of an earthquake are significantly affected in many cases by forward-directivity effects. The resulting seismic action on bridge is characterized by an important pulse type motion that is not considered in many international structural designed codes.
