Predicting and Prolonging the Service Life of Weathering Steel Highway Structures
(University of Waterloo, 2009-08-25)Weathering steel is a high-strength, low-alloy steel which has been proven to provide a significantly higher corrosion resistance than regular carbon steel. This corrosion resistance is a product of the small amounts of ... -
Predicting Pervious Concrete Pavement Performance for Usage in Cold Climates
(University of Waterloo, 2010-01-18)Pervious Concrete Pavement (PCP) has the potential to provide significant benefits. To better understand the technical, economical, and environmental impacts of PCP, the performance must be comprehensively evaluated and ... -
Predicting Subsidence Resulting from Tunnel Excavation
(University of Waterloo, 2010-11-22)As a result of tunnel construction, the ground level surface above will tend to collapse downward as the soil seeks to refill the missing tubular cavity. Many infrastructures that were originally built on that surface may ... -
Predicting the Effectiveness of Post-Weld Treatments Applied under Load
(University of Waterloo, 2010-08-26)Existing steel bridges are subjected to both increasing traffic loads and natural aging, both are capable of causing severe durability problems. Dependable rehabilitation methods are attracting attention as the promising ... -
Predicting the Removal of Micropollutants in Lake Ontario and Grand River using Ozonation
(University of Waterloo, 2019-01-15)Micropollutants occur at low concentrations (µg/L to ng/L), can have a range of environmental and health effects, and can enter surface water through run-off from fields and wastewater discharge. Surface water is used for ... -
Prediction of the static modulus of elasticity in concrete cylinders using resonant tests
(University of Waterloo, 2019-10-15)Concrete is widely used in construction nowadays, and it is crucial that its behaviour conforms to the original design. In every construction site, standard concrete cylinders are cast for quality control. Concrete cylinders ... -
Predictions of Flexural Behaviour of Built-Up Cold-Formed Steel Sections
(University of Waterloo, 2007-09-13)In recent years, light gauge cold-formed steel members have been used extensively in low and mid- rise residential building construction. In cold-formed steel design there are several applications where built-up box girders ... -
Pressure Sensor Placement for Leak Diagnosis under Demand Uncertainty in Water Distribution Systems
(University of Waterloo, 2019-01-24)Leakages in concealed pipes in urban water distribution systems (WDS) can cause losses of up to 25% of potable water supply in municipalities. These losses are not only a tremendous waste of water but also the energy spent ... -
Principal Component and Independent Component Regression for Predicting the Responses of Nonlinear Base Isolated Structures
(University of Waterloo, 2009-01-23)Peak base displacement is one of the most important quantities in the design of base-isolated buildings. During the preliminary stages of design, a nonlinear time-history analysis is often not possible or too expensive, ... -
A Probabilistic Approach for the Design of an Early Warning Source Water Monitoring Station
(University of Waterloo, 2007-08-30)This thesis involves the design of an early warning source water monitoring station for a riverine source of drinking water. These stations provide downstream water utilities with advanced notification of contamination ... -
A probabilistic approach to vibration-based modal identification using mobile sensors
(University of Waterloo, 2019-10-08)Vibration-based modal identification is the process of analyzing vibration measurements in order to identify the modal properties of the structure, namely the modal frequencies, damping ratios, and mode shapes. The quality ... -
Probabilistic Assessment of Common Cause Failures in Nuclear Power Plants
(University of Waterloo, 2013-05-22)Common cause failures (CCF) are a significant contributor to risk in complex technological systems, such as nuclear power plants. Many probabilistic parametric models have been developed to quantify the systems subject to ... -
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 ... -
