Seismic Assessment of Unreinforced Masonry Buildings in Canada
Unreinforced masonry (URM) structures have shown to be susceptible to significant damage during strong earthquakes. Vulnerability assessment of URM buildings is needed so that appropriate mitigation strategies can be implemented. The existing Canadian practice consists of rapid seismic screening of buildings to assign priorities for further and more refined assessments, followed by refined analysis of individual critical buildings.
Design and Assessment of Reinforced Concrete Columns in Uplift due to Internal Building Detonations
Current research with respect to the protection of civilian infrastructure against complex blast loading conditions is primarily focused towards the effect of external explosive sources. As a consequence, the general literature on internal building detonations and specifically in the context of protective design and assessment of structures against these loading conditions is incomplete. Existing guidelines developed for comparatively noncomplex external explosive blast remain unconservative when applied to internal building detonations due to blast wave confinement and complex interaction with structural components. In particular, reinforced concrete (RC) columns in internal blast environments are subjected to time-variant uplift forces coupled with lateral pressures leading to destabilisation and a critical loss of structural integrity. Research presented in this thesis provides an original understanding towards: (i) – the influence of transient uplift forces on the vulnerability of RC columns subject to lateral blast pressures and, (ii) – design and assessment of RC columns against the effect of time-variant coupled uplift and lateral blast pressures due to internal building detonations.

Response of Bridge Structures Subjected to Blast Loads and Protection Techniques to Mitigate the Effect of Blast Hazzards on Bridges
Bridges are critical to the transportation system especially at the time of crisis. They are essential for rescue missions, evacuations, and rapid distribution of aid and medical supplies. Bridges are highly...
The Analysis of Collapse of Deteriorated Framed Buildings
rogressive building collapse occurs when failure of a structural component leads to the failure and collapse of surrounding members, possibly promoting additional collapse. It is a complex, nonlinear dynamic...
