Improving seismic site response analysis for non-standard sites
… deposits. In particular, I focus on aspects of site response analysis, i.e. the modelling of the modulation of seismic waves by soil deposits. The main goal of the thesis is to improve site response analysis for "non-standard" sites, which are those for which the general assumptions of shallow …

Evaluation of Site Response Analysis for Vertical Ground Motions in LS-DYNA Using Geotechnical Downhole
This study was motivated by the desire to conduct site-specific vertical site response analysis. The main body of knowledge in this field is limited to horizontal shaking, as such a goal of this study was to extend that knowledge to vertical shaking. Current practice for predicting vertical ground …

Seismic site response analysis and extraction of dynamic soil behavior and pore pressure response from downhole array measurements
Seismic site response analysis is commonly used to predict ground response due to local soil effects. Advancements in the knowledge of shear-induced excess pore pressure generation has led to the development and implementation of pore pressure response models for site response analysis with …

Sensitivity tests between Vs30 and detailed shear wave profiles using 1D and 3D site response analysis, Las Vegas Valley
Site characterization is an essential aspect of hazard analysis and the time-averaged shear-wave velocity to 30 m depth "Vs30" for site-class has become a critical parameter in site-specific and probabilistic hazard analysis. Yet, the general applicability of Vs30 can be ambiguous and much debate …

Probabilistic Site Response Analysis and Soil-Structure Interaction: A Data Science and Statistical Investigation Utilizing a Comprehensive Dataset in Japan and the US
Site response analysis (SRA) plays a crucial role in the performance-based design ofstructures subjected to earthquakes. It allows for the prediction of ground motion and the subsequent effects on structures. While the accuracy of current SRA methodologies has been the focus of much research, there …

Seismic evaluation of the U3ax/bl landfill in the Area 3 Rwms, Nevada Test Site, Nevada
A site evaluation, a seismic hazard analysis and a site response analysis were performed for the U3ax/b1 landfill which is located within the Area 3 Radioactive Waste Management Site of the Nevada Test Site. The site evaluation included application of the Spectral-Analysis-of-Surface-Waves method …

Quantification of Uncertainties for Conducting Partially Non-ergodic Probabilistic Seismic Hazard Analysis
Estimating local site effects and modifying the uncertainty in ground motion predictions are two indispensable parts of partially non-ergodic site-specific PSHA. Local site effects can be estimated using site response simulations or recorded ground motions at the site. When such predictions are …

Effects of Site Response on the Correlation Structure of Ground Motion Residuals
… analyses. This paper considers the effects of site response, at given sites, on the correlation structure of normalized residuals. This is achieved by performing site response analyses for two hypothetical soil profiles using a set of 85 rock input motions. Results show that there is no …

Evaluation of cyclic behavior of dense sands under multidirectional loading using centrifuge tests
… shear stress – shear strain – volumetric strain response. NPPs founded on a thick deposit of dense coarse-grained soil may experience nontrivial settlements due to small, but accumulated volumetric strains during an earthquake. Studies that have investigated the seismic response of granular are …

Post processing of cone penetration data for assessing seismic ground hazards, with application to the New Madrid seismic zone
… is the most efficient means for geotechnical site characterization and the evaluation of seismic ground hazards. In this thesis, software systems including ShearPro, ClusterPro, and InSituData, are developed to automate post processing of these SCPTu data. ShearPro is developed to automate the …

Improvements to the Assessment of Site-Specific Seismic Hazards
The understanding of the impact of site effects on ground motions is crucial for improving the assessment of seismic hazards. Site response analyses (SRA) can numerically accommodate the mechanics behind the wave propagation phenomena near the surface as well as the variability associated with the …

Dynamic soil modeling in site response and soil-large pile interaction analysis
… are implemented in non-linear one-dimensional site response analysis for small and large strains. The first formulation introduces an approach to construct a frequency-independent viscous damping matrix which reduces the over-damping at high frequencies, and therefore, the filtering at those …

Development of Computational Tools for Characterization, Evaluation, and Modification of Strong Ground Motions within a Performance-Based Seismic Design Framework
… ground motions that would induce the critical response in the structures being designed. The quantification of this concept, however, is not easy. Unlike the linear response of a structure, which can often be obtained by using a single spectrally modified ground acceleration history, the …

Regionally adaptable ground-motion Prediction Equations (GMPEs) for seismic hazard analysis
… equations (GMPEs), from a data- rich region/site where they have been derived to a data-poor region/site, is one of the major challenges associated with the current practice of seismic hazard analysis. Due to the fre- quent use in engineering design practices the GMPEs are often derived for …

Nonlinear site amplification functions for Central and Eastern North America
Site amplification functions are used to modify ground motions from a reference bedrock condition to a surface condition based on the geologic features of the site of interest. Site amplification has been extensively studied and evaluated empirically for seismic regions such as the Western United …
