There is an acute need for research to develop value-added applications for wood and wood products such as Cross-Laminated-Timber (CLT). One prominent target area are mid- and high-rise structures. In seismic regions, such as Western Canada, connectors must provide ductility to otherwise rigid building systems composed of CLT panels. There are a number of options available, one of the most promising are Self-Tapping-Screws (STS). The objective of the project is to develop design guidance for CLT assemblies connected by STS for large structures, considering seismic loads.
This research investigates how a neighbourhood in London, Ontario may be designed to be both sustainable and resilient, where “resilient” means capable of dealing with future shocks and stresses. One major future shock/stress will be climate change impacts, such as extreme temperature or precipitation. This research will also conduct preliminary energy modelling of a simplified community using both current and future London temperatures.
Non destructive testing (NDT) methods are way to assess health condition of structures and infrastructures like bridges, underground pipelines, and buildings. Different kind of physical properties of material are basis of NDT methods. The most important of these properties are wave’s velocity, electrical conductivity, electro-magnetic, and magnetic properties. Magnetic property is especial characteristic for such kind of metals which their name is ferromagnetic material. Iron and steel are main ferromagnetic materials for making infrastructures.
The goal of this research is to explore the extent to which building information models (BIM) can be extended into the operations, maintenance and continuous optimization of CIRS, the Centre for Interactive Research on Sustainability, and the most high-performance building on the UBC campus. The project team will develop and implement a BIM of the CIRS basement to apply BuiltSpace software for tracking and interacting with key infrastructure assets.
A new load-bearing precast concrete wall panel system has been proposed that uses composite materials instead of steel for reinforcement to reduce the level of heat loss through them and increase their R-Value. The panels will undergo destructive structural testing to determine how well the composite material system compares to a similar wall design that uses steel reinforcement. Bending tests, axial tests, and combined bending/axial tests will be preformed.
The project consists of a study on the disposal and upgrading of dried and dehydrated sludges from the treatment of municipal and industrial wastewater. The study would be limited to the province of Quebec. As a specialist in the treatment of wastewater, Degremont supplies high performance technologies for the dehydration and drying of wastewater treatment sludges. The most appropriate system for handling the sludge needs to be optimized.
Development of stormwater management plans in Ontario has focused primarily on sizing of conveyance infrastructure and stormwater management ponds that mitigate the receiving water impacts of new developments. The focus has shifted in recent years towards the implementation of Low Impact Development (LID) that emphasizes the control of stormwater runoff at the source.
Urban stormwater re-use is gaining acceptance in Canadian jurisdictions as a means to offset anticipated increases in potable water demand from urbanization and climate change. S2e Technologies has partnered with Queen's University to determine if a net economic benefit can be achieved from potable water savings in large-scale stormwater re-use facilities in Canada. The new partnership between s2e Technologies and Queen’s will examine the economic feasibility of large-scale stormwater re-use in a Showcase Community in London, ON.
While electric vehicles (EVs) are generally viewed as non-polluting and environmentally friendly, EV utilization brings other concerns such as: range anxiety, battery charging issues, cost of electricity, and network overload. Furthermore even though EVs are better for the environment in comparison with the traditional vehicles powered with internal combustion engine, they are still vehicles on the road contributing to road congestion. This study aims to address the above mentioned shortcomings of EVs by investing in a door-to transit station shared E-Taxi system.
Olfactometry is the science of using human subjects to measure odours without bias, as no instrument yet can replace the human nose. Recently, the method presenting odours to panellists has been identified as a potential element affecting response and measurement variability. Furthermore, the sensitivity of electronic noses also developed to measure odours remains an issue. The objective of the research is to use 3 odours and present them in 3 different ways to 6 panellists, and compare panelists' response to that of two widely used commercial noses.
