Mould contamination is of growing concern in our indoor environment and affects people of all ages every day. As an ideal place for microbial growth, mould growth in HVAC and fan coil systems (individual in-suite heating and air-conditioning systems) in the ductwork is often overlooked because it is not as readily visible. However, exposure to mould spores and fragments can often cause severe problems and allergic reactions.
This research will focus on designing an apparatus and developing a testing protocol for determining the capacity of helical piles in collaboration with Stable Ground Solutions. A helical pile is a type of deep foundation that consists of a shaft and helix or multiple helices. The testing of piles can be expensive and time consuming using current standard testing methods. There is also a lack of research and publications focused on helical piles and therefore they are not commonly used. This project will deliver a detailed design of the apparatus for the industry to fabricate the prototype.
For the continuation of the MITACS internship, the intern will be analyzing the effect of variable liner dimension on separate green roof systems. The data collected from several design storms, in addition to, natural precipitation will be used to determine which system best reduces peak flows from green roofs. The intern will also be involved in working on an integrated stormwater management plan and low impact, sustainable development methods.
The proposed research aims to develop general design parameters needed to optimize a large-scale landfill biocover for countering landfill methane emissions at Brady Road Resource Management Facility (BRRMF). The intern will conduct column studies aimed at determining the optimum combination of yard waste and leaf compost and biosolids compost for facilitating the growth of methane oxidizing bacteria known as methanotrophs in the landfill cover.
This project will characterize the ability of vintage (1930 - 1970s) pipeline materials to support large deformations and develop numerical simulation tools capable of predicting the onset of failure. Of particular interest to this project is the analysis of geotechnical hazards including the ground movements that could impact pipelines including landslides and subsidence events.
The intent of this internship is to examine the barriers and opportunities policies set for the private sector to invest in affordable housing that is attractive to young adults in St. Catharines, Ontario. The rational behind this research stems from the gap in academic literature on young adults and their experiences with affordable housing. Although there is a wealth of knowledge on housing challenges, very little is known about how these challenges are affecting young adults in a Canadian context.
Slab bands are a common structural system in North America due its general economy. At the slabband/column connection, unbalanced moments are being transferred that could lead to a common failure mechanism termed punching shear failure. This type of failure occurs when the column and a portion of the slab punches through the remaining slab. Thus, it is critically important from a design prospective to identify and quantify how these unbalanced moments are being transferred, specifically as shear stresses at the slab-column connection.
Recent years have witnessed a boom in the construction of modern high-rise buildings in megacities around the world. It is important to design a high-rise building that can effectively withstand both wind and earthquake loads. Nonetheless, in current practice, the design of highrise buildings for wind and earthquakes is done independently. Hence, there is an urgent need to develop a set of integrated design guidelines for both wind and earthquake loads.
The objectives of this project are to develop and validate numerical and analytical tools to evaluate the critical loads on energy infrastructures, focusing on transmission lines (TLs) and nuclear power plants (NPP) due to high intensity wind (HIW) in the form of tornadoes and downbursts. There is a clear lack of tools used to estimate the forces required for the design of energy infrastructures to resist HIW events. The new tools will assist the Boundary Layer Wind Tunnel (BLWTL), the industrial sponsor, to assist clients from the utility industry in Canada.
The research project will use a case study approach at the proposed Transit Hub for the City of Kitchener. In its objectives, the research will focus on the opportunities for a high quality green public space/square to better integrate a new LRT line and a new GO/VIA rail station into the surrounding city. It will look at how to create a healthy people oriented public environment that will also transfer people from one mode of transit to another.
