Seismic Performance of Geosynthetic-Soil Retaining Wall Structures
(2011-04-29)Vertical inclusions of expanded polystyrene (EPS) placed behind rigid retaining walls were investigated as geofoam seismic buffers to reduce earthquake-induced loads. A numerical model was developed using the program FLAC ... -
Shear Transfer Strength of Concrete After Exposure to Elevated Temperature
The most consumed construction material in the world, concrete, is largely composed of coarse aggregate. Thus, the physical and mechanical properties of aggregates play a significant role in determining the performance of ... -
Short and Long Term Behaviour of Externally Bonded Fibre Reinforced Polymer Laminates With Bio-Based Resins for Flexural Strengthening of Concrete Beams
(2016-03-22)The use of bio-based resins in composites for construction is emerging as a way to reduce of embodied energy produced by a structural system. In this study, two types of bio-based resins were explored: an epoxidized pine ... -
Short Term Characteristics and Environmental Aging of Bio-Resin GFRP Tested in Tension and for Confinement of Concrete Cylinders
(2013-08-26)Conventional fiber reinforced polymers (FRPs) require polymers such as epoxies that are not biodegradable, which have a significant impact on the environment. The first phase of the thesis aims at replacing conventional ... -
Short- and Long-Term Performance of Compressed Earth Blocks and Sandwich Panels with Natural Skins
(2014-11-05)A drastic increase in environmental awareness has increased demand for renewable materials, energy efficient design and low embodied energy. Two technologies that purport to address this demand are Compressed Earth Blocks ... -
Simplified Design Equations and Laboratory Tests for Pipe Joints
(2013-01-31)The joint may be considered a weak point along the pipe and can have a major impact on pipe performance. However, little research has been conducted in regard to joint design. To improve current structural design criteria, ... -
Simulating Remediation of Trichloroethylene in Fractured Bedrock by Thermal Conductive Heating Using the Numerical Model TMVOC
(2013-01-07)A thermal conductive heating (TCH) pilot test was conducted at the Naval Air Warfare Center (NAWC) in West Trenton, New Jersey in 2009 in collaboration with TerraTherm, Inc., the Naval Facilities Engineering Services Center ... -
Simulating solute transport in discretely fractured rocks: Computational limitations and a hybrid method
To investigate the computational limitations arising when simulating large-scale groundwater flow and solute transport using a 3D control volume finite element model (the FE model) in discrete-fracture mode, numerical ... -
Simulations of Nottawasaga River Plume
Water quality degradation, in the form of undesirable algae, occurs near the Nottawasaga River mouth and along Wasaga Beach, located in southeastern Georgian Bay, Ontario. Runoff from fertilized agricultural areas, in the ... -
Size, Dynamics and Consequences of Large-Scale Horizontal Coherent Structures in Open-Channel Flows: an Experimental Study
(2013-09-20)This thesis concerns the occurrence of the large-scale bed and plan forms known as alternate bars and meandering, and the internal structures of the flow associated with their formation. The work is to be viewed as an ... -
Sludge Accumulation and Characterization in Decentralized Community Wastewater Treatment Systems with Primary Clarifier Tanks at Each Residence
(2009-04-29)Sludge accumulation, treatment and disposal can represent a high percentage of the operating cost for a wastewater system. This is especially important for small-scale and onsite wastewater treatment systems, where sludge ... -
Socially Just Engineering: Power, resistance, and discourse at Site 41
(2011-09-21)While engineers and their patrons have always claimed that technology has advanced the common good, I intend to show that more often than not engineers have been mercenaries for those at the center of knowledge, power, and ... -
Soil Characterization and Hydrogeological Modelling of an Episodic Retrogressive Landslide in Champlain Sea Clay
(2016-04-27)Champlain Sea clay is a sensitive marine clay deposited within the St. Lawrence lowlands during the later stages of the Wisconsin glaciation. The sensitive clay has been known to transform from a relatively brittle material ... -
Soil-structure Interaction Associated with Buried PVC Sewers with Vertical Risers
(2009-01-05)The design of service connections to deeply buried sewers involves a number of challenges. In practice, the loads that develop from vertical risers can damage the Tee or Wye fitting to which it is connected. This thesis ... -
Stability of Buried Steel and Glass Fibre Reinforced Polymer Pipes Under Lateral Ground Movement
(2013-04-19)As vast networks of high pressure buried energy pipelines traverse North America and other continents, the stability of such essential buried infrastructure must be maintained under a variety of earth loading conditions. ... -
Static Liquefaction of Loose Granular Landslides
Highly mobile landslides can have devastating impacts on infrastructure and human life. In order to mitigate the risks of these landslides, it is critical to understand how they are triggered and the mechanism behind their ... -
A Streamlined Energy Efficiency Indicator for Water Distribution Systems
The conveyance of water through centralized water distribution systems is energy intensive. With growing urban populations and deteriorating buried infrastructure, these costs are expected to increase. Energy indicators ... -
Strengthening Damaged Reinforced Concrete Beams and Slender Columns Using Ultra-High Modulus CFRP Plates
(2013-09-24)This thesis investigates the application of ultra-high modulus carbon fiber reinforced polymer (CFRP) plates to strengthen damaged reinforced concrete beams and slender columns. In the first phase, two different pre-repair ... -
