Fatigue Behavior of Concrete Bridge Decks Cast on GFRP Stay-in-Place Structural Forms and Static Performance of GFRP-Reinforced Deck Overhangs
(2013-09-18)The first part of the thesis addresses the fatigue performance of concrete bridge decks with GFRP stay-in-place structural forms replacing the bottom layer of rebar. The forms were either flat plate with T-up ribs joined ... -
Fatigue Performance of a Hybrid CFRP/STEEL Splice Detail for Modular Bridge Expansion Joints
(2013-07-24)As traffic demand on bridges increases, loading cycles on critical components will increase, reducing their service life. Modular bridge expansion joints, which are imperative to allowing the bridge superstructure to move, ... -
A Feasibility Analysis of Site-Level Stormwater Reuse for Commercial Developments in Canada
(2013-08-19)Municipalities are experiencing a growing water management challenge as a result of population growth in water-dependent communities. The rising cost of potable water, in addition to limits placed on stormwater discharges, ... -
Feasibility of glucose recovery from municipal sewage sludges as feedstocks using acid hydrolysis
(2008-07-28)In light of rising costs in fossil fuels and petroleum, as well as the strain on this largely non-renewable resource, the conversion of biomass, in this case waste biomass, to value-added products is becoming more attractive. ... -
Field and Lab Scale Performance of Phosphorus Removal in Post-Wetland Slag Filters Treating Aquaculture Wastewater in Cold Climates
(2013-04-24)Eutrophication, caused by phosphorus and nitrogen overloading, is a global pollution problem for our fresh water lakes and streams. Regulatory bodies have developed treatment guidelines for point-source pollution to address ... -
A Field and Numerical Study of Heat and Solute Transport in a Discrete Fracture
Two tracer experiments were conducted in a highly-transmissive discrete rock fracture to explore the transport properties of solute and heat, and the influence of fracture heterogeneities. The experiments were conducted ... -
Field investigation and simulation of nutrient control in a fish-hatchery wastewater stabilization pond system
(2015-06-09)The aquaculture sector has been the fastest growing animal food producer since the 1970’s. With such a fast growth rate, ecological problems have arisen due to the lack of ability to control nutrient run off in coastal ... -
Field Measurements of Surface Displacements from Pipe Bursting
(2009-01-15)Two field studies of surface displacements during pipe bursting were conducted. The first field study consisted of a controlled experiment in clay soil. Three vitrified clay pipelines, each at a different burial depth, ... -
Field Monitoring of Landslide Deformation Using Low Altitude Photogrammetry
(2012-02-01)The Ottawa/Gatineau region has significant deposits of sensitive glacial marine clay. As these deposits have risen due to isostatic rebound, these materials have been incised by various watercourses, carving river valleys ... -
Field monitoring of pile walls designed to selectively stabilize slow moving landslides in Peace River, Alberta
The Peace River region of Alberta, Canada is a highly active landslide area characterized by creeping landslides in weak lacustrine clays and silts. Much of the infrastructure for the region is built upon historical ... -
Field Performance of Exposed Geosynthetic Composite Liner Systems
(2015-07-03)Geosynthetic clay liners (GCL) overlain by a geomembrane (GMB) in a geosynthetic composite liner system in landfill liner and other waste containment applications can be left exposed for weeks, months, or in some extreme ... -
A Field Scale Evaluation of Wrinkles in Exposed HDPE Geomembranes
(2012-07-05)Intact geomembranes are barriers to advective aqueous flow and are often a key component in the design of composite bottom liner and cover systems. During installation, the combination of solar heating, a high coefficient ... -
Field-Scale Monitoring and Laboratory Simulation of Geosynthetic Liners During Construction and After Placement of Waste
(2015-05-01)Two physical issues of geomembrane wrinkle deformations and downslope shear deformations – that need to be considered to obtain good long-term geomembrane liner performance – are examined. First, field-scale monitoring ... -
Finite Element Analysis of Profiled High Density Polyethylene Stormwater Arches Under Live Loading
The physical response of a profiled high-density polyethylene stormwater retention arch structure under shallow burial subjected to design truck loading was investigated, with an emphasis on finite element modelling of the ... -
The First Moving Load Simulator for Testing Bridges in Canada and its Application on a Full Scale Precast Box Girder
This thesis describes the development of a unique Moving Load Simulator (MLS) for testing bridge superstructure with a footprint up to 4x17 m, and its first application to test a full scale B900 prestressed concrete box ... -
Flexural Behaviour of Fibre Reinforced Polymer Strengthened Reinforced Concrete Beams at Elevated Temperatures
(2013-03-04)Fibre reinforced polymers (FRPs) have gained considerable popularity as a building and repair material. In particular, FRPs have been an economical means of extending the life of structures. As time passes, an increased ... -
Flexural Behaviour of Sandwich Panels Composed of Polyurethane Core and GFRP Skins and Ribs
