(University of Waterloo, 2014-05-23)Based on a diverse consortia of research completed within the last 15 years, it has been found that Pharmaceutical Compounds (PCs) are present in detectable levels within a variety of environmental matrices, including tap ... -
Fatigue Assessment of Repaired Highway Bridge Welds Using Local Approaches
(University of Waterloo, 2015-07-02)This thesis aims to address a number of unanswered questions regarding repair and fatigue design of welded joints in bridges, including developing and evaluating repair methods for enhancing the fatigue behaviour of web ... -
Fatigue Behaviour of Aluminum Friction Stir Welds Under Highway Bridge Conditions
(University of Waterloo, 2018-01-22)Friction stir welding (FSW) is a solid state joining process performed by rotating a cylindrical tool with a short protrusion between the two metal pieces to be joined. The combination of frictional and deformation heating ... -
Fatigue Behaviour of GFRP-Reinforced UHPC Closure Strips in Prefabricated Bridge Deck Applications
(University of Waterloo, 2016-09-01)Accelerated bridge construction techniques allow for bridges to be constructed or replaced more quickly in order to save commuter time and money. One of these techniques involved the use of prefabricated bridge deck panels, ... -
Fatigue Behaviour of Steel Girders Strengthened with Prestressed CFRP Strips
(University of Waterloo, 2010-05-20)Steel bridges and structures often need strengthening due to increased live loads, or repair due to corrosion or fatigue cracking. This thesis explores the use of adhesively bonded prestressed carbon fibre reinforced ... -
The Fatigue Behaviour of Tension Lap Spliced Reinforced Concrete Beams Strengthened with Fibre Reinforced Polymer Wrapping
(University of Waterloo, 2016-10-25)Many reinforced concrete structures containing lap splices were constructed before modern bond and fatigue design codes came into existence and are subjected to fatigue loading, which may lead to a bond failure even when ... -
The Fatigue Behaviour of Welded and Bolted Shear Connectors in Composite Highway Bridges
(University of Waterloo, 2018-09-26)At present, many Canadian bridges are overdue for rehabilitation or replacement. In the case of steel-concrete composite bridges, the shear connection between the concrete deck and the steel girders is a vital element of ... -
Fatigue Bond Behaviour of Corroded Reinforcement and CFRP Confined Concrete
(University of Waterloo, 2007-07-13)Bond in a reinforced concrete (RC) structure is the interaction force that transfers force between the steel and concrete. It influences the structural performance and serviceability of a structure under both static and ... -
Fatigue Characterization of Asphalt Mixes with Polymer Modified Asphalt Cement
(University of Waterloo, 2018-11-14)Asphalt pavement cracking is the most prevalent distress in pavements. In flexible pavements, fatigue cracking is a major cause of deterioration and can significantly reduce the service life of pavements [1]. Fatigue ... -
Fatigue Design and Behaviour of Carburized Steel
(University of Waterloo, 2022-05-02)Steel is an essential component used in infrastructure, automobiles, machines and many other areas due to its low cost and high tensile strength. Carburization is a heat treatment process commonly used to harden and ... -
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 ... -
