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.

Assessment of bioremediation of petroleum contaminated soils under cold climate

The main objective of this research is the feasibility assessment of bioremediation of petroleum contaminated soils for cold climate conditions. LLSRI as the industrial partner is interested to evaluate feasibility of conducting bioremediation through the cold season to extend its operation and generate more revenue.

Development of a carbon calculator for underground utility construction

Destructive effects of Green House Oas (OHO) emissions on the environment such as climate change and global warming are some oftoday's major concerns. According to the "Environmental Protection Agency" (EPA) U.S 2010, construction is the third highest source ofOHO emission between other industrial sections. Underground utility construction projects are considered as one of the major areas of the construction projects. Also Underground infrastructure is aging across North America; hence rehabilitation or new installation of pipelines and facilities has become inevitable.

Identifying dominant anaerobic microorganisms for degradation of benzene

Contamination of soils and groundwater with gasoline often results in the development of anaerobic zones. Benzene is particularly persistent under anaerobic conditions even in the enhanced anaerobic biodegradation (EAB) process. Degradation of benzene has been demonstrated under nitrate-reducing condition, and sulphate-reducing condition. However, information of dominant indigenous species within the microorganisms for degrading benzene is still limited.

Integrated modeling for systematically examining the performance of the Kennedale constructed wetland for a clean Canadian water environment

Constructed wetland is a critical water infrastructure in major Canadian cities like the city of Edmonton, which treats wastewater including storm water by reducing the suspended solids and the related contaminants before entering into receiving waterbody. The design and evaluating the performance of a constructed wetland requires accurate prediction of flow fields and particle pollutants settling behaviours.

Performance assessment of a high efficiency 1000x concentrated photovoltaic (CPV) system

Meeting the growing energy demands in a sustainable fashion is one of the greatest challenges of this century. This projects aims to evaluate a promising renewable energy source: concentrated photovoltaics (CPV). The configuration developed by our partner promises to offer utility-scale solar power at competitive prices, making it a viable alternative. It is based on large steel and glass structures that focus the incident light to reach over 1000x concentration onto a large array of high performance triple junction photovoltaic cells.

Sediment Removal Frequency Optimization for Wet-Detention Stormwater Management Ponds

Sediment build-up in stormwater management ponds decreases their overall capacity to hold water and reduces their efficiency, in terms of controlling pollution. For this reason, and in order to comply with government regulations, municipalities must remove the sediment periodically. Determining when maintenance is required is difficult because it depends on a number of factors, and the actual cost of sediment removal from a wet pond is difficult to predict.

Improving Concrete Sustainability and Durability by Optimization of Total Aggregate Gradations

 

To reduce the impact on natural resources and extend the lifetime of existing quarries, this research will attempt to reduce the large quantities of quarried rock that are currently wasted for simply not meeting current aggregate grading requirements in standard construction specifications, even though some of those wasted size fractions would improve the quality and sustainability of concrete. By optimizing aggregate particle packing, more workable and durable concretes can be produced while also reducing the carbon dioxide producing, and energy-intensive, cement content.
