Modelling Guidance for Low Impact Development Practices

To combat the degradation of receiving water resulting from stormwater runoff approaches that focus on retaining and infiltrating stormwater at the source, referred to as Low Impact Development (LID) practices, are being proposed more frequently in recent years. Toronto and Region Conservation Authority recently initiated monitoring of precipitation and runoff from a large industrial site, comprised of several buildings and extensive paved areas, in which several LID practices have been constructed: rainwater harvesting system, biofilters, vegetated swales and porous pavement.

Development a New Design Method for Geosynthetic Reinforced Walls and Slopes

The main objective of this research project will be to formulate a design approach for walls and slopes that are reinforced with geo-reinforcement using the basic analytical framework developed by Weerasekara and Wijewickreme (2010). The intern will participate in the development of this methodology under the direct guidance of Drs. Wijewickreme and Weerasekara. The design approach will be validated by modeling the performance of some of the well-documented reinforced slope/ wall.

Viscoelastic Coupling Dampers for Enhanced Dynamic Performance of a High-Rise in Toronto

The biggest challenge faced by structural engineers in the design of high-rise structures is to control the dynamic responses of these structures due to wind and earthquake vibrations. While the traditional techniques of stiffening and adding vibration absorbers can mitigate the vibrational response to a degree, they also increase the construction cost and result in a loss of leasable space in the building structure.

Effect of anisotropy in thermal-hydro-mechanical properties on casing and caprock integrity

Argillaceous shales comprise a large proportion of rocks in most sedimentary basins. They serve as caprocks in the projects of petroleum industry. Maintaining borehole and caprock integrity is to prevent disasters such as borehole collapse and leakage through caprocks. Thermal-hydro-mechanical properties of argillaceous shales have decisive controls on the integrity analysis. As a kind of clay rich geomaterial, argillaceous shales feature in oriented fabric and have anisotropic behaviors.

Candu nuclear reactor: Civil and mechanical engineering analysis

CANDU 6 is a Canadian technology 700 MWe class nuclear power reactor. CANDU 6 reactors are performing well on four continents with over 150 reactor-years of excellent and safe operation. Candu Energy is a Canadian-based company that is enhancing this reactor design based on the experience and feedback that was gained in the development, design, construction, commissioning and operational support of the 11 CANDU 6 unit fleet operating in five countries.

Effect of dam-rock interface irregularity of the seismic response of gravity dams

Dam failures may lead to catastrophic consequences, extending far beyond the immediate neighbourhood of the dam site due to sudden reservoir release or overtopping. The main objectives of this research project are: (i) to apply state-of-the-art simulation tools to investigate the seismic response of a real dam in Québec to formulate guidelines on the significance of including the effects of the irregularity of dam-rock interface and vertical component of earthquakes in the evaluation of the seismic response of dams.

Evaluating impacts of social web-based networks on travel sharing

The specific aim of this study is to examine the demand for a social-network based dynamic ridesharing system called FacePorter. The study will also be focused on the role that social networks can play in facilitating this ride-sharing Program. The University of Calgary population will be examined as potential users for such service. A combination of stated preference and revealed preference survey would be conducted to examine the willingness of the University population to use this system and the factors which would contribute to its success.

Validation of Giatec corrosion detection device on a small-scale reinforced concrete bridge deck

The project is designed to verify the performance of Giatec iCORTM hand-held device for non-destructive assessment of deteriorations in concrete structures caused by corrosion. Various laboratory experiments will be conducted using iCORTM at the University of Ottawa on a corroded concrete testing slab. The results will be validates against those obtained by accurate corrosion assessment methods which are destructive, time-consuming and expensive.

Optimization of Actiflo system for Portage La Prairie water treatment plant

Water treatment plants in Manitoba use surface water with high organic content as their source of water supply. Organic carbon reacts with disinfecting chlorine forming potentially carcinogenic disinfection byproducts. Portage la Prairie water treatment plant is an example of typical Manitoba lime/soda water treatment plants facing the challenge of removal of organic carbon. Coagulation and Granular Activated Carbon (GAC) are used in this plant for removal of Dissolved Organic Carbon (DOC).

Our previous studies showed that DOC cannot be efficiently removed by these two processes.

Seismic design of eccentrically-braced frames with & without vertical ties for irregular buildings

The project aims at developing cost-effective steel seismic force resisting systems for multi-storey building structures that can achieved superior performance in terms of seismic stability and amplitude of damage. The system can be used for the construction of new structures or the seismic rehabilitation of existing structures. The system could also be implemented when adding storeys to existing buildings to increase the usable floor space. The internship will permit to develop and verify the applicability of the new systems to actual building constructions.
