Automated Pipe Spool Recognition in Cluttered Point Clouds
(University of Waterloo, 2016-05-06)Construction management is inextricably linked to the awareness and control of 3D geometry. Progress tracking, quality assurance/quality control, and the location, movement, and assembly of materials are all critical ... -
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 ... -
Development of a Ridged Slip-Resistant Connection for Modular Aluminum Bridge Deck Applications
(University of Waterloo, 2018-12-04)Aluminum is a lightweight material that possesses excellent corrosion resistance and has been shown to be an attractive alternative to steel and concrete for the construction and rehabilitation of bridge structures. It ... -
Development of Analysis Tools for the Facilitation of Increased Structural Steel Reuse
(University of Waterloo, 2016-08-11)Reuse of structural steel can be more attractive than recycling in many cases, if associated costs and risks are lowered, and if externalities are considered. The costs and risks typically associated with steel reuse arise ... -
Evaluation and Calibration of Pedestrian Bridge Standards for Vibration Serviceability
(University of Waterloo, 2017-08-14)An increase in the use of lightweight materials and emphasis on architecturally appealing designs has resulted in lively pedestrian bridges. A prominent example for this is the serviceability failure of the London Millenium ... -
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, ... -
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 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 ... -
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 ... -
Impact of Spatial Cognitive Abilities on the Effectiveness of Augmented Reality in Construction and Fabrication
(University of Waterloo, 2018-09-04)Modular construction has emerged to help address the challenges posed to the construction industry by stagnant productivity rates and a shortage of skilled labor as it allows for greater automation and for work to be ... -
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 ... -
Partial Joint Penetration Welds in Aluminum Structures
(University of Waterloo, 2020-09-29)Aluminum structures are becoming more and more common in Canada and the world as engineers and decision-makers become more aware of the possibility to lower life cycle costs. Aluminum's corrosion resistance, light weight ... -
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 ... -
Risk-Based Decision Support Framework for Managing Excessive Geometric Variability Issues in Modular Construction
(University of Waterloo, 2019-03-15)Managing and controlling excessive dimensional and geometrical variability (i.e., tolerances) of modular components and assemblies during the fabrication, transportation, and erection phases, represents a major issue in ... -
