Quantification of Uncertainties for Conducting Partially Non-ergodic Probabilistic Seismic Hazard Analysis
… site effects must be incorporated into the hazard analyses. This research focuses on the challenges specific to conducting partially non-ergodic site-specific PSHA using recorded ground motions or site response analysis. The main challenge in estimating local site effects using recorded data …

Seismic Analysis of a United States Navy Structure Using Finite Element Modeling
… to disengage from the structure due to seismic activity. A concern about the seismic loading of the structure was raised by an inspection team. The concern was that, in the event of an earthquake, the lifting rod would disengage from the structure due to vertical seismic actions. In …

Seismic Site Response and Extraction of Dynamic Soil Behavior From Downhole Array Measurements
… impact on anticipated surface motions. PSHA-NL, probabilistic seismic hazard analysis with nonlinear site effects, can be used to estimate seismic hazard with the effect of deep deposits. This thesis extends the PSHA-NL procedure to incorporate a finite fault model in PSHA without applying …

Disaggregated Seismic Hazard and the Elastic Input Energy Spectrum: An Approach to Design Earthquake Selection
… earthquake selection problem is fundamentally probabilistic. Disaggregation of a probabilistic model of the seismic hazard offers a rational and objective approach that can identify the most likely earthquake scenario(s) contributing to hazard. An ensemble of time series can be selected on the …

Estimation of Non-Linear Seismic Site Effects for Deep Deposits of the Mississippi Embayment
The second part of the thesis describes the probabilistic seismic hazard analysis with non-linear site effect performed in the ME to develop site coefficients. Current site coefficients, proposed in National Earthquake Hazard Reduction Program (NEHRP), are used with USGS hazard maps to develop site …

An investigation into the geomorphology of the Hebron Fault, Namibia, using a satellite-derived, high-resolution digital elevation model (DEM)
… plate. The country also has little recorded seismicity with the largest earthquake on the International Seismological Center (ISC) catalogue being MW 5.4. If the Hebron fault scarp was formed in a single event, this would represent a MW 7.3 earthquake. SCRs do occasionally experience large …

Improvements to the Assessment of Site-Specific Seismic Hazards
… 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 input motion and soil properties. As a result, SRA …

Improved ground motion intensity measures for reliability-based demand analysis of structures
… Earthquake Engineering (PBEE), evaluating the seismic performance (or seismic risk) of a structure at a designed site has gained major attention, especially in the past decade. One of the objectives in PBEE is to quantify the seismic reliability of a structure (due to the future random …

Considering a Seismically Active Leech River Valley Fault Zone in Southwestern British Columbia
… of Victoria, British Columbia, Canada. New paleoseismic studies suggest at least three surface-rupturing earthquakes have exceeded a moment magnitude (M) of 6 within a proposed Leech River Valley Fault Zone (LRVFZ) within the last 9,000 years. We examine the impact of an active LRVFZ to predicted …

Partitioning Uncertainty for Non-Ergodic Probabilistic Seismic Hazard Analyses
… ground motion parameters is critical for Probabilistic Seismic Hazard Analyses (PSHA). This is particularly important for critical facilities that are designed for long return period motions. Non-ergodic PSHA is a framework that allows for this proper accounting of uncertainties. This, in …

Development of Computational Tools for Characterization, Evaluation, and Modification of Strong Ground Motions within a Performance-Based Seismic Design Framework
… they can be input into time-domain nonlinear analysis of structures. The generation of these acceleration histories is cumbersome and daunting. This is especially so due to the sheer magnitude of the data processing involved. The purpose of this thesis is the development and documentation of …

Multi-objective optimal seismic design of buildings using advanced engineering materials
Although seismic safety remains a major concern of society--and unfortunately this observation has been underpinned by recent earthquakes--economy and sustainability in seismic design are growing issues that the engineering community must face due to increasing human population and excessive use of …
