DeltaVs: A Method for Detecting Significant Layer Boundaries in Surface Wave Inversion Results
Publisher: American Society of Civil Engineers
Abstract: Surface wave testing is a powerful tool for noninvasive seismic site characterization. It includes a wide variety of active-source and passive-wavefield methods [e.g., spectral analysis of surface waves (SASW), ...
Intramethod Variability in ReMi Dispersion Measurements and Vs Estimates at Shallow Bedrock Sites
Publisher: American Society of Civil Engineers
Abstract: The refraction microtremor (ReMi) method uses a linear array of receivers to record passive noise stress waves, thereby negating the need for a strong active source such as those typically employed in other linear-array ...
Comparison of State-of-the-Art Approaches Used to Account for Spatial Variability in 1D Ground Response Analyses
Publisher: ASCE
Abstract: A significant amount of seismic site response research over the past decade has focused on our abilities to replicate recorded ground motions at borehole array sites, where both the input (rock) and output (surface) ground ...
What Spatial Area Influences Seismic Site Response: Insights Gained from Multiazimuthal 2D Ground Response Analyses at the Treasure Island Downhole Array
Publisher: American Society of Civil Engineers
Abstract: Site-specific subsurface conditions are known to significantly influence the frequency content and amplitude of seismic ground shaking. When attempting to model these effects, known as seismic site effects, most studies ...
Frozen and Unfrozen Shear Wave Velocity Seismic Site Classification of Fairbanks, Alaska
Publisher: American Society of Civil Engineers
Abstract: Relationships between seismic site classification and surficial geology for the city of Fairbanks, Alaska, for both frozen (winter) and unfrozen (summer) surface conditions are investigated in this article. The work is ...
Mapping Dispersion Misfit and Uncertainty in Vs Profiles to Variability in Site Response Estimates
Publisher: American Society of Civil Engineers
Surface-Wave Dispersion Approach for Evaluating Statistical Models That Account for Shear-Wave Velocity Uncertainty
Publisher: American Society of Civil Engineers
Estimating Unbiased Statistics for Fundamental Site Frequency Using Spatially Distributed HVSR Measurements and Voronoi Tessellation
Publisher: ASCE
Abstract: A site’s fundamental resonance frequency (f0), or its reciprocal, the fundamental period (T0), is a critical parameter in seismic studies due to its proven ability to aid in predicting local site effects (i.e., freq ...
Vs-Based Evaluation of Select Liquefaction Case Histories from the 2010–2011 Canterbury Earthquake Sequence
Publisher: American Society of Civil Engineers
Abstract: The 2010–2011 Canterbury earthquake sequence included a number of events that triggered recurrent soil liquefaction at many locations in Christchurch, New Zealand. However, the most severe liquefaction was induced by the ...
