Nonlinear Finite Element Analysis of Reinforced Concrete Slab-Column Connections with Headed Stud/Bolt Shear Reinforcement Subjected to Punching Shear
(University of Waterloo, 2022-08-29)While many experimental tests have been conducted by various researchers on the punching behaviour of reinforced concrete flat slabs supported on columns with headed stud/bolt shear reinforcement, there are still many ... -
Shell-Based Finite Element Analysis of Reinforced Concrete Slabs Subjected to Non-uniform Stress Distribution at Column Connection Regions
(University of Waterloo, 2022-08-29)RC flat plates design provisions and mechanical models have been developed in a highly-idealized manner and, as a result, loosely represent the performance of real-world RC flat plates. Part of this inadequacy is due to ... -
Experimental Investigation and ANN Modelling of the Behavior of Asphalt Binders Modified with Novel Geopolymers
(University of Waterloo, 2022-08-24)The design of asphalt pavement has an impact on a country’s economic and environmental development. The main factors limiting the service life of flexible pavements are severe weather and increasing traffic volumes. Rutting ... -
Strategically Coupled Inertial Flow and Interfaced Evolution (SCI-FIE) Models for Dissolution Mining
(University of Waterloo, 2022-08-23)Mineral dissolution or dissolution mining is a technology for underground mineral extraction. The space developed after the mining may be a desirable reservoir for the storage of natural gas and hydrocarbons or compressed ... -
Improved Streamflow Simulation through Ensemble and Stochastic Conceptual Data-driven Approaches
(University of Waterloo, 2022-08-18)To better understand the complexities of water movement on earth, hydrologists have developed process-based hydrological models (HMs) and data-driven models (DDMs), both of which have been applied to a host of water resources ... -
Analysis of Concrete Deep Beams with Fibre Reinforced Polymer Reinforcements using Indeterminate Strut-and-Tie Method
(University of Waterloo, 2022-08-18)Fibre-reinforced polymer (FRP) bars have gained popularity in industry to reinforce concrete. They are noncorrosive, strong in tension, but they are less stiff than traditional steel bars and fail in a brittle manner. ... -
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 ... -
Evaluation of Mechanical and Durability Properties of Concrete with Recycled Materials for its use in Interlocking Concrete Pavement
(University of Waterloo, 2022-08-17)The use of coarse recycled concrete aggregates (CRCA) in concrete as a replacement for natural aggregate (NA) has recently sparked a lot of attention. The use of CRCA is gaining acceptance as more research into its performance ... -
Methods in Modelling of Composite Materials with Microstructure
(University of Waterloo, 2022-08-12)Composite material properties are dependent on their microstructure. To adequately model these materials, a revised formulation of elasticity that accounts for microstructural effects must be considered. Size dependent ... -
Comparative Assessment on Static O-D Synthesis
(University of Waterloo, 2022-08-02)Recognizing the benefits of data and the information it provides to travel demand is pertinent to network planning and design. Technological advances have led the ability to produce large quantities and types of data and ... -
A Pilot Study Regarding the Use of Food Waste Grinders in a Multi-Unit Residential Building
(University of Waterloo, 2022-07-25)This study evaluated the impact of food waste grinders (FWGs) in multi-unit residential buildings (MURBs) that also had access to green bins (GBs) on solid waste and wastewater generation. A 15-month technical sampling ... -
Investigating the Behaviour of Short-Span FRP-Reinforced Glulam Beams
(University of Waterloo, 2022-07-20)The broader availability of engineered wood products has generated a resurgence of wood used as a construction material over the past few decades. To further promote the use of timber, a solution aimed at increasing ... -
Improving hydrological process representation in lake and forest dominated watersheds
(University of Waterloo, 2022-07-15)Hydrological models are simplified representations of the natural surface water dynamic system. This thesis focuses on improving these representations to make them more realistic and thus more appropriate tools to simulate ... -
Closed Loop Geothermal System Design
(University of Waterloo, 2022-06-17)In contrast to other renewable sources (e.g., wind and solar) that may only be intermittently available throughout a day or year, geothermal resources provide a carbon-free and sustainable source of energy for base-load ... -
Operational Robustness of Drinking Water Treatment Plants with Respect to Turbidity Representing Normal, Severe and Unprecedented Weather Events
(University of Waterloo, 2022-06-16)Drinking water treatment plants (DWTPs) are required to supply safe drinking water continuously to the consumers to protect public health and sanitation. The adverse effects of climate change can influence raw water quality, ... -
Biofiltration-based “green technology” as a techno-ecological nature-based solution for drinking water treatment and climate change resilience
(University of Waterloo, 2022-06-02)While drinking water treatment process design is based on current and anticipated source water quality, changing climate makes it increasingly difficult to anticipate drinking water source quality and treatability. Although ... -
Comprehensive Repetitive Scheduling for Linear and Scattered Infrastructure Projects
(University of Waterloo, 2022-05-16)The majority of civil infrastructure projects involve activities that are repeated across a number of units (e.g., linear highway sections; or scattered multi-bridge repairs). While repetition represents a potential for ... -
Simultaneous nitrification, denitrification, and phosphorus removal at low temperatures
(University of Waterloo, 2022-05-10)Simultaneous nitrification, denitrification, and phosphorus removal (SNDPR) has been demonstrated to be a promising technology for carbon, nitrogen, and phosphorus removal. However, SNDPR has not been fully studied at low ... -
Development of a Framework to Evaluate Asphalt Binder and Plant Produced Asphalt Mixes for Acceptance in Canada
(University of Waterloo, 2022-05-05)Asphalt binder, sometimes referred to as asphalt cement binder, or asphalt cement, is the binder that holds the aggregates together in asphalt mixes for asphalt concrete pavements. In Canada, asphalt binder properties are ... -
