Pre-cast prestressed hollow core (HC) slabs are special design components that have not received much research attention. Several structures where deterioration due to chloride penetration is problematic often contain concrete slabs. Multi-story parking structures, bridges, commercial and industrial buildings are common examples of structures exposed to adverse chemical environments. A strengthening technique resistant to such […]

Water resources worldwide have recently appeared as vulnerable to climate change that may both reduce water supply and increase water demand, leading to frequent and/or severe water shortages. Water resources in Canada are also at risk posed by climate change. Sustainable water resources management plays a vital role in reducing the vulnerability of the water […]

It has been a common practice to discharge water, wastewater and industrial effluents into open channels such as rivers and streams.   Such discharges, in the form of jets, often enter shallow bodies of water typically found in rivers and coastal bays.  In contrast to the existing body of knowledge on unconfined turbulent jets in which […]

  Chinese cities are amongst the fasted growing cities in the world and they have per capita greenhouse gas (GHG) emission rates that are similar to western cities. This research quantifies GHG emissions for the three Chinese city-provinces of Beijing, Shanghai and Tianjin. A computer model is then developed for projecting the future growth in […]

  Toronto’s CN Tower is the world tallest freestanding tower structure. Built between 1973 and 1975, this giant communication and observation tower represents the extensive design process that lasted six years. The structural design of the Tower was one of the major challenges of design process. The structure has been designed based on the latest […]

  There are about 180 public water treatment plants in Manitoba relying on surface water with high organic content as their source of 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 […]

  There is a recurring problem of cost overrun on mega engineering projects with a budgeted cost of $1 Billion or more. Examples of mega projects include dams, hydro electric projects, and high speed rail projects. The basic reason for cost overrun can be attributed to underestimation of project cost, increases in material and labor […]

  Load resistance of hollow-core (HC) slabs is influenced by several factors. In the literature, the most influential ones among those found to be geometry of HC slabs and amount and distribution of the applied prestressing load during production. So, this research is aiming to simulate HC slab units under loading by means of numerical modeling […]

There are about 180 public water treatment plants in Manitoba relying on surface water with high organic content as their source of supply. Organic carbon in the water reacts with chlorine during water disinfection. This reaction forms carcinogenic compounds w hich pose a health risk for people consuming the water. The Waterhen water treatment plant is an example […]

With my research time at Halsall I wish to contribute to a body knowledge that will assist with Halsall’s current needs and future directions. A review of relevant literature on methods and procedures for designing more economical, fire-resistant buildings would serve Halsall by providing them with a reference works with which their design engineers can […]

  Annually over a million scrap tires are generated in Saskatchewan which in the past have been disposed of in landfills and streams. At the same time, Saskatchewan has also experienced a drastic increase in truck traffic on roadway infrastructure that is ageing. This has resulted in the need for the construction of new roads and the rehabilitation […]

  Water and sewer research centers have developed protocols to examine and grade assets and infrastructure already in use. These protocols are widely accepted across the world and municipalities have been using them for assessing their pipeline conditions, which is the foundation of pipeline rehabilitation projects and a key factor for their success. The Water […]
