Performance-based earthquake engineering with the first-order reliability method
Performance-based earthquake engineering is an emerging field of study that complements the prescriptive methods that the design codes provide to ensure adequate seismic performance of structures. Accounting for uncertainties in the performance assessments forms an important component in this area. …

Numerical modeling of a bridge system & its application for performance-based earthquake engineering
Many bridges have been damaged during earthquakes. The severity of the recorded damage varies from column failures and bridge deck collapse due to joint unseating to pile and abutment foundation failure due to lateral spreading. In most of these cases, soil pile-structure interaction (SPSI) has …

Bayesian Methods for Intensity Measure and Ground Motion Selection in Performance-Based Earthquake Engineering
The objective of quantitative Performance-Based Earthquake Engineering (PBEE) is designing buildings that meet the specified performance objectives when subjected to an earthquake. One challenge to completely relying upon a PBEE approach in design practice is the open-ended nature of characterizing …

Behaviour and modelling of the inelastic response of concrete and steel-concrete infrastructures subjected to low-cycle fatigue
… the seismic response of infrastructures under an earthquake requires a careful evaluation of the level of damage of structural elements. In this thesis, typical case studies are considered, such as a concrete tunnel lining and a composite steel-concrete bridge. In the first part of the thesis, a …

Machine Learning Based Analysis Of Civil Infrastructure In The Presence Of Sparse Data
<p>The high computational cost of estimating engineering demand parameters (EDPs) via finite element (FE) models, which incorporate uncertainties in earthquake events and material properties, limits the application of the Performance-Based Earthquake Engineering (PBEE) framework. Previous efforts …

Probabilistic Assessment of Non-Ductile Reinforced Concrete Frames Susceptible to Mid-America Ground Motions
The infrequent nature of earthquakes in the Central and Eastern United States (CEUS), and the fact that none with intensity comparable to the New Madrid sequence of 1811 12 or the Charleston earthquake of 1886 has occurred in the past century, have caused the earthquake hazard in the region to be …

Performance Assessment of Seismic Resistant Steel Structures
… stems from two different studies related to this performance assessment of seismic resistant systems. The first study compares the performance of newly developed and traditional seismic resisting systems, and the second study investigates many of the assumptions made within provisions for …

Seismic experimental analyses and surrogate models of multi-component systems in special-risk industrial facilities
Nowadays, earthquakes are one of the most catastrophic natural events that have a significant human, socio-economic and environmental impact. Besides, based on both observations of damage following recent major/moderate seismic events and numerical/experimental studies, it clearly emerges that …

Improved ground motion intensity measures for reliability-based demand analysis of structures
In Performance-Based 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 …

Stochastic Ground Motion Models for Uncertainty Quantification in Earthquake Engineering
Earthquakes are among the most destructive natural hazards, causing significant loss of life and economic damage. Traditionally, seismic risk is computed by combining three conditionally independent components: hazard, vulnerability, and exposure. However, recent advancements in computational power …
