Duong, Eric

Steel fabricators and connection designers in the building construction industry often rely on traditional connection design methods, which involve using connection design software or spreadsheets to simulate and design connections with the goal of minimizing costs associated with fabrication and...

Behaviour of the unstiffened wide flanged member is not characterized by the available literature or current design standards. Torsional moment applied on the one flange unstiffened member causes the member to undergo local distortions. Conventionally, to avoid these local distortions stiffeners...

Residual stresses can have a significant impact on the stability of structural members. In the case of I-section beam elements, such stresses can impact lateral--torsional buckling (LTB) capacity, particularly in the inelastic range. I-sections are typically fabricated by either rolling as a...

Current design procedures for extended shear tab connections tend to be conservative and often do not include considerations for axial load. To address these problems, an investigation into the behaviour of extended shear tabs was completed by testing 23 full-scale specimens. Both unstiffened and...

It has become common for steel fabricators to find torsional loads included in the design documents of many industrial steel structures. These loads arise in wide-flange beam-to-column moment connections when the beam is subject to weak axis bending, which in turn, is transferred to the column as...

Modularization of buildings comes in several types, from prefabricated members to full volumetric models. Recently, the introduction of modular construction methods brought numerous benefits to the construction industry. Reducing construction time and costs together with improving quality and...

Lateral–torsional buckling (LTB) is a failure mode that is associated with simultaneous vertical displacement and twisting of a beam when subjected to flexural loading. LTB behaviour is generally well understood for I shaped steel beams; however, the LTB behaviour of T shaped steel beams is not...

Extended shear tab connections are efficient for both fabrication and erection where a beam would otherwise need to be coped to clear the flanges of the supporting member, and are therefore used extensively in industry. Stability issues can arise as the plate becomes longer and more slender, as...

Embedded plates are commonly used to facilitate connecting structural steel members to reinforced concrete building elements such as walls and columns. Due to a lack of readily available industry-wide standard embedded plate designs, embedded plates are often custom designed for each project....

The objective of this research is to develop design methods for steel plate shear wall in low and moderate seismic regions, and to examine its performance under accidental blast. Different practical details are investigated to reduce the force demands on the boundary frame of the wall system and...
