Acceptance Criteria for Ultrasonic Impact Treatment of Highway Steel Bridges
(University of Waterloo, 2012-08-30)The need for rehabilitation of bridges has become a critical challenge due to aging and an increase in traffic loads. Many of these bridges are exceeding their design fatigue life. Since many of these bridges are structurally ... -
Bond Behaviour of Concrete Beams with Glass Fibre Reinforced Polymer Bars Under Fatigue Loading
(University of Waterloo, 2019-01-17)Since the 1980s and after the aerospace industries faced several periods of economic difficulty, the companies that produced fibre-reinforced polymers (FRPs) started to introduce them as new materials for construction ... -
Bond Behaviour of Corroded and CFRP Repaired RC Beams Subjected to Monotonic and Repeated Loading
(University of Waterloo, 2012-09-27)All reinforced concrete (RC) design theories are based on the assumption that concrete exhibits a perfect bond with the steel reinforcement. The bond between steel and concrete is essential to the transfer of the load ... -
Evaluating the Effect of a Self-Healing Elastomer on the Self-Healing Properties of Asphalt Cement
(University of Waterloo, 2020-09-25)Asphalt pavements exhibit an interesting behaviour when the traffic loading is removed. The chemical structure of asphalt cement lends itself to the ability to heal damage and improve the longevity of the pavement. This ... -
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 ... -
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 ... -
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 ... -
The Impact of Portland Cement on the Performance of Cold In-Place Recycled Pavement
(University of Waterloo, 2022-12-06)In place recycling of existing asphalt pavement is a rehabilitation strategy, which the Ministry of Transportation Ontario (MTO) adopted decades ago. Asphalt emulsion is the most common type of bitumen stabilizing agent ... -
Modelling Fatigue Deterioration and Retrofitting in Bridge Management Systems
(University of Waterloo, 2016-02-11)Similar to any other structure exposed to the elements, bridges deteriorate and degrade over time. This deterioration can result in costly maintenance and repair if it is addressed properly or damage and even loss of life ... -
Predicting the Effectiveness of Post-Weld Treatments Applied under Load
(University of Waterloo, 2010-08-26)Existing steel bridges are subjected to both increasing traffic loads and natural aging, both are capable of causing severe durability problems. Dependable rehabilitation methods are attracting attention as the promising ... -
Probabilistic Strain-Based Fracture Mechanics Analysis of Weldments
(University of Waterloo, 2019-08-13)Welded joints are considered to be one of the most critical locations in structural components from a fatigue perspective because of high stress concentrations near the weld toe region, the presence of tensile residual ...
