Fatigue Flexural Behaviour of Reinforced Concrete Beams with Non-Prestressed and Prestressed Basalt Fiber Reinforced Polymer Bars
(University of Waterloo, 2015-06-18)Basalt fibers have recently been introduced as a promising alternative to the existing fiber reinforced polymer (FRP) family. The mechanical properties of basalt FRP (BFRP) bars are, generally, better than those of glass ... -
Fatigue of Aluminum Welds in Canadian Highway Bridges
(University of Waterloo, 2010-08-30)Aluminum is the most common metal in the world and its high strength to weight ratio, along with excellent corrosion resistance, can provide efficient solutions for the design and rehabilitation of highway bridge structures. ... -
The Fatigue Resistance of Headed Shear Stud Connectors in Steel-Precast Composite Girders
(University of Waterloo, 2017-01-20)Extensive research dating back to 1965 has been conducted on the fatigue performance of headed shear stud connectors in steel and cast-in-place composite girders. However, little research has been conducted specifically ... -
Fatigue Testing and Analysis of Aluminum and Steel Partial Joint Penetration (PJP) Welds for Bridge Applications
(University of Waterloo, 2023-05-30)Partial joint penetration (PJP) welds are a cost-effective alternative to full penetration welds and have certain advantages, especially in situations where a full penetration weld is unnecessary and the stress on the weld ... -
Feasibility of Using Traffic Data for Winter Road Maintenance Performance Measurement
(University of Waterloo, 2014-09-29)Winter road maintenance (WRM) operations, such as plowing, salting and sanding, are significant to maintain both safety and mobility of highways, especially in countries like Canada. Traditionally, WRM performance is ... -
Feasibility Study of Lean Oil Sand as Base and Surface Material on Gravel Roads in Alberta
(University of Waterloo, 2019-04-18)A major concern has been raised by Imperial Oil Inc. that dust issues extensively occurred on the gravel roads in Kearl Lake Oil Sand site in northern Alberta, Canada. Some mitigation measures had been utilized to minimize ... -
Federal Road Management for Sub-Saharan African Nations: A Nigerian Case Study
(University of Waterloo, 2009-04-24)The World Bank specifically indicates that poor transport infrastructure and services in sub-Saharan Africa are serious obstacles to poverty reduction (Plessis-Fraissard, 2007). Two thirds of Africa's rural population, who ... -
Fermentation of Food Waste in a Leach Bed Reactor- Effects of pH and Inoculum to Substrate Ratio
(University of Waterloo, 2018-12-19)A more sustainable method for the treatment of accumulated food waste, instead of landfilling, is in urgently need. Fermentation is one of the most promising waste-to-energy technologies for energy recovery from food waste. ... -
A field and Numerical Investigation of the Pressure Pulsing Reagent Delivery Approach
(University of Waterloo, 2011-09-30)The efficacy of injection-driven remediation techniques for non-aqueous phase liquid (NAPL) source zones is limited by the principle that fluid flow is focused along paths of least hydraulic resistance. The pressure pulse ... -
Field and Numerical Investigation to Determine the Impact of Environmental and Wheel Loads on Flexible Pavement
(University of Waterloo, 2009-08-24)There is a growing interest for the use of mechanistic procedures and analytical methods in the design and evaluation of pavement structure rather than empirical design procedures. The mechanistic procedures rely on ... -
Field Evaluation and Performance Analysis of Different Pre-wetting Ratios for Sustainable Salting
(University of Waterloo, 2018-09-20)In countries like Canada road safety and mobility could be compromised to a great extent during winters due to deterioration of road surface conditions (RSC). Adverse winter weather conditions such as ice, frost, and ... -
A Field Study of Airflow in a High-Rise Multi-Unit Residential Building
(University of Waterloo, 2014-01-23)Airflow into, out of, and within buildings is fundamental to their design and operation as it can affect occupant health and comfort, building durability, and energy consumption. This thesis works to develop the understanding ... -
Fine Sediment Contributions to Cyanobacterial Growth: Potential Threats to Drinking Water Reservoirs
(University of Waterloo, 2019-01-14)In the drinking water industry, the transport and release of nutrients such as phosphorus (P) to the water column is largely overlooked in reservoir management. Phosphorus is considered the key limiting nutrient for algal ... -
Finite Difference-Boundary Element Methods in Infinite and Semi-infinite Media in Geomechanics
(University of Waterloo, 2013-02-22)The engineering problems in Geomechanics and Geotechnical fields are commonly treated through the infinite or semi-infinite media. The best approach to solve these problems numerically is by coupling a finite element or a ... -
Finite Element Analysis Workflow for Heat Straightening of Impact-Damaged Steel Bridges
(University of Waterloo, 2015-09-11)Impacts between over-height vehicles and steel bridges are common throughout North America and the resulting bridge damage is unpredictable and sudden. Heat straightening is an alternative to replacing steel members and ... -
