A Probabilistic Corrosion Model for Copper-Coated Used Nuclear Fuel Containers
(University of Waterloo, 2022-08-18)Lifetime predictions of used nuclear fuel containers destined for permanent storage in Deep Geological Repositories (DGRs) are challenged by the uncertainty surrounding the environment and the performance of both containers ... -
Probabilistic Finite Element Analysis of Structures using the Multiplicative Dimensional Reduction Method
(University of Waterloo, 2015-12-23)It is widely accepted that uncertainty may be present for many engineering problems, such as in input variables (loading, material properties, etc.), in response variables (displacements, stresses, etc.) and in the ... -
Probabilistic Life Cycle Assessment of Safety Valves
(University of Waterloo, 2020-05-14)The objective of this this thesis is to develop a probabilistic model for assessing the life cycle performance of safety valves used in the nuclear piping system. The life cycle performance is quantified in terms of ... -
Probabilistic Models for Life Cycle Management of Energy Infrastructure Systems
(University of Waterloo, 2007-08-02)The degradation of aging energy infrastructure systems has the potential to increase the risk of failure, resulting in power outage and costly unplanned maintenance work. Therefore, the development of scientific and ... -
Probabilistic Strain-Based Fracture Mechanics Analysis of Weldments
(University of Waterloo, 2019-08-13)Welded joints are considered to be one of the most critical locations in structural components from a fatigue perspective because of high stress concentrations near the weld toe region, the presence of tensile residual ... -
Probability distribution of the seismic damage cost over the life cycle of structures
(Elsevier, 2018-05-01)In the life-cycle analysis, the total cost of damage caused by earthquakes is a significant but highly uncertain component. In the current literature, the seismic risk analysis is largely limited to the evaluation of the ... -
Progressive-Failure Analysis of Steel Building Structures under Abnormal Loads
(University of Waterloo, 2007-04-18)Engineered structures are designed to resist all expected loadings without failure. However, structural failures do occasionally occur due to inadequate design and construction, especially for extreme and abnormal loads. ... -
Proof of Concept: A Relocatable Panelized Mass Timber Modular Building System Designed for Disassembly and Reassembly
(University of Waterloo, 2023-06-28)Canada has been experiencing a housing crisis for several years now with specifically Ontario having the lowest housing supply in the country. To combat this crisis, several rapid housing initiatives and projects have been ... -
Punching Shear Retrofit Method Using Shear Bolts for Reinforced Concrete Slabs under Seismic Loading
(University of Waterloo, 2008-04-10)Reinforced concrete slab-column structures are widely used because of their practicality. However, this type of structures can be subject to punching-shear failure in the slab-column connections. Without shear reinforcement, ... -
Punching Shear Retrofit of Concrete Slab-Column Connections with GFRP Shear Bolts
(University of Waterloo, 2008-09-24)Over the life span of a structure it may become necessary to retrofit, or strengthen certain components or elements. This may be due to construction errors, changes in use and occupancy, or changes due to material ... -
Push-Pull Tests to Support In Situ Chemical Oxidation System Design
(University of Waterloo, 2012-01-19)The problems associated with the contamination of groundwater environments by non-aqueous phase liquids (NAPLs) such as chlorinated solvents, gasoline and manufacturing gas plant (MGP) residuals, including their distribution ... -
Quality Assessment of Composite Materials using Ultrasonic Non-Destructive Testing Methods
(University of Waterloo, 2020-09-17)Non-destructive ultrasonic evaluation (NDE) is commonly used for assessment of civil infrastructure and characterization of construction materials. It is an efficient technique that could save millions of dollars with ... -
Quantification of PFAS Fate in Sludge Handling Systems
(University of Waterloo, 2023-08-14)Per- and polyfluoroalkyl substances (PFAS) have been detected in biosolids, raising concerns regarding their potential leaching into soils, groundwater, and plants when biosolids are land applied. In this study, the fate ... -
Quantifying Greenhouse Gas Mitigation Measures during Provincial Highway Design, Construction, and Maintenance Activities
(University of Waterloo, 2020-12-18)In response to the increasing need to address global climate change, departments of transportation have adopted and promoted diverse mitigation measures to reduce source and enhance sinks of the greenhouse gas (GHG) emissions ... -
Quantifying Pavement Sustainability For Ontario Highways
(University of Waterloo, 2010-08-26)With the emerging trend of sustainability, sustainable infrastructure is highly regarded by the general public. Sustainable pavement is also a concept that has driven many research motivations today. These motivations ... -
Quantifying the Effects of Winter Weather and Road Maintenance on Emissions and Fuel Consumptions
(University of Waterloo, 2015-09-24)Winter road maintenance (WRM) has significant benefits including improving road safety and reducing traffic delay caused by adverse weather conditions. It has also been suggested that WRM is beneficial in terms of reducing ... -
