Behavior of Slender GFRP Reinforced Concrete Columns
This paper presents an experimental and analytical study on slender concrete columns reinforced with glass fiber-reinforced polymer (GFRP) bars. The experimental program included ten concrete columns with rectangular ... -
Biodegradation kinetics of individual and mixture non-steroidal anti-inflammatory drugs in an agricultural soil receiving alkaline treated biosolids
Land application of biosolids is one potential source of pharmaceuticals and personal care products (PPCPs) into agricultural soils. Degradation is an important natural attenuation pathway that affects the fate and transport ... -
Blue-Green and Benthic: A Workshop on Monitoring, Mitigation and Management of Cyanobacteria in Atlantic Canada. Final Report.
WORKSHOP SUMMARY Since the 2018 Atlantic Canadian Cyanobacteria Workshop, we have seen a rapid increase in the number of waterbodies (recreational and drinking water supplies) under public advisories, exposing gaps in ... -
Bond-Slip Analytical Formulation toward Optimal Embedment of Concrete-Filled Circular FRP Tubes into Concrete Footings
This paper presents a robust analytical model for a moment connection of concrete-filled fiber reinforced-polymer (FRP) tubes (CFFTs) to concrete footings. The CFFT connection is based on a simple approach of direct embedment ... -
Calibration of Reduction Factor for Concrete Columns Strengthened with Unidirectional Fiber-Reinforced Wrapping
Strengthening with fiber-reinforced polymer (FRP) wrapping is a well-established method of retorifiting or upgrading existing concrete columns. The available test data cooreponding to FRP wrapped concrete columns has ... -
Characterizaing sediment physical property variability for bench scale dewatering purposes
A field sampling program was undertaken to assess the variability of physical characteristics of contaminated sediments in a large (160 ha) effluent stabilization lagoon. The objective of this paper is to use this “field ... -
Characterization of Combined Longitudinal and Transverse FRPs for Strengthening Concrete Columns
This paper presents the results of a study on the characterization of combined longitudinal near-surface-mounted (NSM) fiber-reinforced polymer (FRP) bars and transverse FRP wraps for strengthening concrete columns. A total ... -
Characterizing Porosity and Diffusive Properties of Monolithic Cement-Based Solidified/Stabilized Materials
This paper presents the application of a single reservoir diffusion test to determine both the effective porosity of a soil-cement matrix and the diffusivity of tritium through saturated, monolithic, cement solidified/stabilized ... -
Chord-end RHS-to-RHS and CHS-to-CHS X-connections with rigid cap plates: Stress concentration factors (Postprint)
For rectangular hollow section (RHS)-to-RHS and circular hollow section (CHS)-to-CHS connections situated near a truss/girder end, reinforcement using a chord-end cap plate is common; however, for fatigue design, formulae ... -
Circular hollow section X-connections near an open chord end: stress concentration factors (Postprint)
This paper presents a numerical finite element (FE) investigation to determine stress concentration factors (SCFs) for circular hollow section (CHS)-to-CHS X-connections near an open chord end. Previous large-scale experiments ... -
Closed-Form Model and Parametric Study on Connection of Concrete-Filled FRP Tubes to Concrete Footings by Direct Embedment
Concrete-filled fiber reinforced polymer (FRP) tubes (CFFTs) have been introduced as a new system for piles, columns and poles. A simple moment connection based on direct embedment of the CFFT into concrete footings or ... -
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 ...
