Particle size effects on breakage of ACT aggregates under physical and environmental loadings
Aggregates manufactured from fine-grained thermal waste residues using accelerated carbonation technology (ACT) represent a potential sustainable alternative to natural aggregates. However, for these manufactured products ... -
Examining metal migration through geotextiles during dewatering
This paper presents a study conducted to assess the influence that a filter cake deposited on the surface of the geotextile has on the mobility of three metals (Cu, Pb, Zn) during filtration of a contaminated sediment. Two ... -
Historical characterization and spatial distribution of organic contaminated sediment derived from kraft pulp mill effluent.
Organic sediment contaminants [polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans (PCDD/Fs), and polycyclic aromatic hydrocarbons (PAHs)] were assessed using secondary monitoring data from a former tidal ... -
Lateral sand filters are effective for removal of antibiotic resistance genes from domestic wastewater
The ability of lateral flow sand filters, used as on-site wastewater treatment systems (OWTS), to remove antibiotic resistance genes (ARGs), antibiotic resistant bacteria (ARB), and other relevant genetic markers (HF183, ... -
Stress concentration factors for RHS-to-RHS X-connections near an open chord end
This paper presents an experimental and finite-element (FE) study to determine stress concentration factors (SCFs) for directly welded rectangular hollow section (RHS)-to-RHS axially loaded X-connections near an open chord ... -
Design of fillet welds in RHS-to-RHS moment T-connections under branch in-plane bending
Non-linear finite element (FE) models were developed to assess the AISC 360-16 Chapter K design approach for fillet welds in rectangular hollow section (RHS) moment T-connections under branch in-plane bending. The FE models ... -
Fillet weld effective lengths in CHS X-connections. I: Experimentation
For the first time, an experimental test program was conducted to assess the strength of fillet welds in circular hollow section (CHS) connections. Six large-scale, fillet-welded CHS-to-CHS X-connections were designed with ... -
Fillet weld effective lengths in CHS X-connections. II: Finite element modelling, parametric study and design
Finite element (FE) modelling was performed to extend the results of a recently completed experimental test program to evaluate the static strength of fillet welds in X-connections between circular hollow sections (CHS). ... -
Slender RC Columns Strengthened with a Novel Hybrid Strengthening System of External Longitudinal and Transverse FRPs
In this study, the performance of slender circular concrete columns strengthened with a novel hybrid system of longitudinally bonded prefabricated fiber-reinforced polymer (FRP) laminates and transverse FRP wrapping is ... -
Using Heat to Trace Vertical Water Fluxes in Sediment Experiencing Concurrent Tidal Pumping and Groundwater Discharge
Heat has been widely applied to trace groundwater-surface water exchanges in inland environments, but it is infrequently applied in coastal sediment where head oscillations induce periodicity in water flux magnitude/direction ... -
New mechanics-based confinement model and stress–strain relationship for analysis and design of concrete columns wrapped with FRP composites
The analysis and design of concrete columns wrapped with fiber-reinforced polymer (FRP) composites require the mathematical equation of stress–strain relationship and the ultimate conditions (i.e., stress and strain) ... -
Variation of horizontal in situ stress with depth for long-term performance evaluation of the Deep Geological Repository project access shaft
A site characterization program was carried out for a proposed Deep Geological Repository (DGR) project for Ontario Power Generation's (OPG) low- and intermediate-level nuclear waste repository near Kincardine, Ontario. ... -
Analysis of a rock slide stabilized with a toe-berm: A case study in British Columbia, Canada
Practical experience has shown that slope movement can be controlled by the placement of a berm near the toe of the moving mass. During construction of the Revelstoke project (British Columbia, Canada), excavation of a ... -
Tensile Properties of PET FRP with Bio-resin Polymer
This study analyses the mechanical behaviour of polyethylene terephthalate fiber-reinforced polymer (PET FRP) made with a bio-resin polymer matrix. The utilized bio-resin is furfuryl alcohol mixed with phthaloyl dichloride ... -
Self-healing of Engineering Cementitious Composite with Crystalline Admixture Under Different Exposure Conditions
Self-healing mechanisms in concrete can promote healing of cracks with the material produced through the concrete itself. Engineered Cementitious Composites (ECC) is a special category of HighPerformance Fiber Reinforced ... -
Analytical Investigation of Concrete Beam Reinforced with GFRP Rebars Under Low Axial Loading
The main objective of the research presented in this paper was to perform the analytical study to investigate the flexural capacity of the concrete beam reinforced longitudinally and laterally with glass fiber-reinforced ... -
Shear and Bending Behaviour of Short-span Steel-reinforced Concrete-filled FRP Tubes with ±55◦ Fiber Orientation
In this study, steel-reinforced concrete-filled ±55◦ glass-fiber-reinforced-polymer (GFRP) tubes (CFFT) are examined under monotonic loading to understand their shear behaviour. A total of three test specimens with three ... -
Reliability-Based Evaluation of the Stiffness Reduction Factor for Slender GFRP Reinforced Concrete Columns
