Coastal groundwater model calibration using filtered and amplified hydraulic information retained in the freshwater–saltwater interface Postprint
Coastal groundwater flow is driven by an interplay between terrestrial and marine forcings. One of the distinguishing features in these settings is the formation of a freshwater lens due to the density difference between ... -
Compressive Behaviour of Concrete Cylinders Reinforced with Glass Fiber Reinforced Polymer Bars
Current design standards ignore any contribution of glass fiber reinforced polymer (GFRP) bars in concrete in a state of compression. This paper challenged this convention by testing 30 cylinders of 36 MPa concrete to ... -
Contribution of Longitudinal GFRP Bars in Concrete Cylinders under Axial Compression
Contribution of longitudinal glass fiber-reinforced polymer (GFRP) bars in concrete columns under compression has been ignored by current design guidelines. This paper challenges this convention by testing 21 concrete ... -
A Coupled MM5-CMAQ Modeling System for Assessing Effects of Restriction Measures on PM10 Pollution in Olympic City of Beijing, China
In this paper, a coupled MM5-CMAQ modeling system was employed to investigate the PM10 pollution issue in Beijing, China, with a focus on assessing the effects of different restriction policies implemented during and after ... -
Cumulative Impact Energy Absorption of Sandwich Panels with Foam Cores and Flax FRP Facings
In this paper, the cumulative energy absorption of sandwich panels constructed of foam cores and flax fiber-reinforced bio-based polymer (FFRP) faces is studied. Nine sandwich panels were constructed and tested under varying ... -
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 ... -
Design of Single-Sided Fillet Welds under Transverse Load (Postprint)
In North American steel design specifications, a directional strength-enhancement factor is used to increase the predicted strength of fillet welds subjected to transverse loading (i.e., loading at 90° to the weld axis). ... -
Development of a leaching procedure to asses the risk of uranium leaching due to construction and demolition waste
Naturally-occurring uranium can be found at elevated concentrations in groundwater throughout the world, with the potential to cause kidney damage in chronically exposed individuals. Empirical evidence shows that uranium ... -
Diffusion and Sorption of VOCs Through Soil-Cement Materials
This paper presents a laboratory study that assesses the diffusive and sorptive parameters of three volatile organic compounds benzene, ethylbenzene, and trichloroethylene) though cured, monolithic, soil-cement materials. ... -
Durability of Concrete Beams with Bonded FRP Composites made of Flax and Glass Fibers
Synthetic fibers, such as glass fibers, in the form of fiber-reinforced polymer (FRP) composites have been extensively used for the repair and strengthening of existing concrete structures in the past three decades. As ... -
Durability of Flax FRPs Exposed to Accelerated Environmental Conditions
It is well known that synthetic fiber reinforcements, such as glass fibers, elevate the mechanical properties of polymer materials. Considering the synthetic material’s renewability challenges, natural fibers, such as flax ... -
The effect of different dewatering techniques on resulting effluent particle size.
A paucity of literature has compared geotextile dewatering methods to more conventional dewatering methods (i.e. centrifuge, sedimentation) in the context of how geotextile dewatering performs at reducing particulate matter ... -
Effect of Fiber Orientation on Nonlinear Behavior of CFRP Composites
Fiber orientation is one of the important parameters that affect strength and ductility of FRP-confined concrete columns. A number of studies have been conducted on various fiber orientations and wrap thicknesses, but have ... -
THE EFFECT OF FREEZE/THAW CYCLES ON THE PERFORMANCE AND MICROSTRUCTURE OF CEMENT-TREATED SOILS
In this paper, the performance and structural changes in cement-treated soils under influence of freeze/thaw (f/t) exposure are investigated. Specimens from plastic and compacted soil-cement mix designs were exposed to ... -
Effects of long shredded rubber particles recycled from waste tires on mechanical properties of concrete
The goal of this research is to study the mechanical properties of recycled rubber particles extracted from scrap tires in concrete to introduce a sustainable waste management system and subsequently to reduce the use of ...
