Flexural Behaviour of Partially Bonded CFRP Strengthened Concrete T-Beams
(University of Waterloo, 2008-09-26)Fibre-reinforced-polymer (FRP) composites have been widely used for the flexural strengthening of reinforced concrete (RC) structures. Flexural strengthening methods with FRP include external bonding of FRP composites (EB ... -
Flexural Behaviour of Stay-In-Place PVC Encased Reinforced Concrete Walls with Various Panel Types
(University of Waterloo, 2014-08-06)The use of stay-in-place (SIP) formwork has become an increasingly popular tool for concrete structures, providing advantages in construction scheduling and labour reduction. Stay-in-place formwork made of strong materials ... -
Flexural Fatigue Behaviour of Corroded Pretensioned Beams and Their Repair Using Carbon Fibre Reinforced Polymer Sheets
(University of Waterloo, 2015-09-24)The study presented in this thesis investigated the flexural fatigue behaviour of non-corroded and corroded pretensioned beams and examined the use of externally bonded Carbon Fibre Reinforcement Polymer (CFRP) sheets as ... -
Flow and Sediment Routing in Urban Channels with Flashy Hydrographs
(University of Waterloo, 2023-10-20)Urbanization has a major impact on flow and erosion in open channels. By replacing rural land surfaces with impervious surfaces, urbanization causes a decrease in infiltration and an increase in surface runoff and faster ... -
Flume Construction and RFID Tracking Techniques for Fluvial Sediment Transport Studies
(University of Waterloo, 2016-09-28)Sediment transport studies incorporating radio frequency identification (RFID) tracers are becoming a key component in understanding sediment transport dynamics due to the data they provide on spatial and temporal variability. ... -
Foam as a Vehicle for Nanoparticle Delivery in Unsaturated Porous Media
(University of Waterloo, 2019-05-23)Accidental releases, spills, and leaks of petroleum hydrocarbons (PHCs), such as gasoline and jet fuel, can result in subsurface contamination. PHCs that become entrapped as a residual light non-aqueous phase liquid (LNAPL) ... -
Forecasting Pavement Surface Temperature Using Time Series and Artificial Neural Networks
(University of Waterloo, 2008-06-19)Transportation networks play a significant role in the economy of Canadians during winter seasons; thus, maintaining a safe and economic flow of traffic on Canadian roads is crucial. Winter contaminants such as freezing ... -
Formal Hypothesis Testing for Prospective Hydrological Model Improvements
(University of Waterloo, 2016-10-31)New algorithms for simulating hydrological processes are regularly proposed in the hydrological literature. However, the tests used to evaluate the effectiveness of these algorithms are typically no more than history ... -
Fractional Stochastic Dynamics in Structural Stability Analysis
(University of Waterloo, 2013-08-30)The objective of this thesis is to develop a novel methodology of fractional stochastic dynamics to study stochastic stability of viscoelastic systems under stochastic loadings. Numerous structures in civil engineering ... -
A Framework for Efficient Condition Assessment of the Building Infrastructure
(University of Waterloo, 2008-10-21)Currently, in North America, a large percentage of infrastructure assets, including education and healthcare buildings, are deteriorating rapidly due to age and over capacity. The budget constraints under which municipalities ... -
Framework for Scheduling, Controlling, and Delivery Planning for Scattered Repetitive Infrastructure Rehabilitation Projects
(University of Waterloo, 2019-01-07)Public-Sector organizations such as School Boards and Universities are faced with significant challenges to keep their aging facilities operational and reducing the large backlog in infrastructure renewal needs. The cost ... -
Framework for the Strategic Management of Dimensional Variability of Structures in Modular Construction
(University of Waterloo, 2016-09-01)Challenges in construction related to dimensional variability exist because producing components and assemblies that have perfect compliance to dimensions and geometry specified in a design is simply not feasible. The ... -
Freeway Travel Time Prediction Using Data from Mobile Probes
(University of Waterloo, 2010-11-12)It is widely agreed that estimates of freeway segment travel times are more highly valued by motorists than other forms of traveller information. The provision of real-time estimates of travel times is becoming relatively ... -
Freeway Workzone Capacity and Associated Economic Concepts
(University of Waterloo, 2009-01-16)Like many other transportation agencies, the Ministry of Transportation Ontario (MTO) is also using the same work zone closure strategies and standards that it has used for decades. However, the lane closure strategies ... -
Frequency Analysis of Droughts Using Stochastic and Soft Computing Techniques
(University of Waterloo, 2010-05-19)In the Canadian Prairies recurring droughts are one of the realities which can have significant economical, environmental, and social impacts. For example, droughts in 1997 and 2001 cost over $100 million on different ... -
Full-Depth Reclamation with Hydraulic Road Binders
(University of Waterloo, 2020-01-20)According to a recent report, 16.4% of Canadian roads are in a poor or very poor condition. This means 146,255 km of the Canadian roads are either unfit for service or are approaching the end of their service life. The ... -
Future of Canadian Air Quality and Related Health Benefits from Climate Change Mitigation
(University of Waterloo, 2021-05-21)Air pollution has been recognized as the world’s largest environmental health risk. Climate change is expected to exacerbate air pollution. Mitigating the “climate penalty” of climate change on air quality yields air ... -
Gearbox Fault Detection using Synchro-squeezing Transform
(Elsevier, 2016)This paper presents a novel fault-detection method for gearbox vibration signatures using synchro-squeezing transform (SST). Premised upon the concept of time-frequency (TF) reassignment, SST provides a sharp representation ... -
