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 ... -
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. ...
