Coastal groundwater model calibration using filtered and amplified hydraulic information retained in the freshwater–saltwater interface Postprint
(Springer, 2022-07-22)
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 ...
Design of Single-Sided Fillet Welds under Transverse Load (Postprint)
(American Society of Civil Engineers, 2022-09-01)
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). ...
Experimental tests on fillet and PJP welds in CHS moment T-connections (Postprint)
(Elsevier, 2022-09-01)
An experimental program was developed at Dalhousie University to test various unreinforced circular hollow section (CHS)-to-CHS 90° T-connections subjected to branch in-plane bending moment with the objective of determining ...
Circular hollow section X-connections near an open chord end: stress concentration factors (Postprint)
(Elsevier, 2021-02-01)
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 ...
Chord-end RHS-to-RHS and CHS-to-CHS X-connections with rigid cap plates: Stress concentration factors (Postprint)
(Elsevier, 2021-04-01)
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 ...
Reliability Assessment of Concrete-Filled RHS Beam-Column Design Provisions (Preprint)
(Springer, 2023-08-01)
Revisions were recently proposed to the way in which concrete-filled hollow structural section members are handled in CSA S16. These revisions were based on previous research, comparisons to experiments, and an approximate ...
