Research

Below is a sample list of my research interests and current projects I am working or involved with (not everything is listed for example). Interested and prospective students are encouraged to contact me about these projects or other possible proposals.

Torontos

Our work is heavily focused on practical research which can be applied in consultancy. The majority of my partners are leading firms based in Toronto and Ottawa.

Research Interests:

  • Sustainable construction materials (timber, concrete, steel)
  • Structural Fire Resilience
  • Fire safety engineering
  • Human behavior that influences architecture and design
  • Novel deformation measurement technologies
  • Stadium Design
  • Heritage and Adaptive re-use

Current Research:

  • Sustainable and Environmentally friendly materials 

Recycled concrete aggregate lvl

This project is  environmental engineering themed. The research has had $235,000 in funding commitments primarily from NSERC allocated since 2013 to consider developing sustainable materials for use in Canadian infrastructure. We are currently looking at engineered timber and sustainable concretes (using waste materials for aggregates and cements). Our concrete work currently involves the development of concrete mixes with recycled concrete aggregates for ambient and high temperature conditions. The research is currently focusing on research and development of supplementary cement alternatives from waste materials. Our timber work involves studying engineered timbers in fire (LVL and Glulam). Our focus is on Adhesive behaviour (what binds engineered timber together). This is part of a collaboration with the University of Canterbury in New Zealand.  We are currently collaborating on new measurement technologies in this project with NIST in the United States.

  • Human Behavior and Architectural considerations in Fire

MassMotion software is used to predict how people will behave in a structure on fire with reduced uncertainties.

As part of a collaboration with Arup Canada, we are studying how to make long term care homes safer if a fire occurs (are modelling work is currently described here ). This research utilizes Carleton University’s strength in Architectural Conservation and Sustainability Engineering and we offer one of the only courses on this subject in Canada. Several papers have recently been published which all can be accessed in the publications section.  The project is funded primarily through a $25,000 grant in support with Arup, Canada. We are now considering re-use of heritage structures and stadium design.

  • Steel Resiliency in Canada 

This research is aims to develop alternative design solutions which can be implemented within the current Canadian building code as well as appropriate education to train engineers to perform performance based designs. Two student trainees are participating. Various industry supporters are advising in-kind including the global engineering conulstancy firm Entuitive (our collaboration is described here). The project is financed by a CISC-ICCA (Canadian Institute of Steel Construction) grant multi year running until 2018, which is helping the facilitation of the students studying this topic.

  • Post-tensioned structures (concrete and timber) in fire

The project considers both the ambient and high temperature performance of post-tensioned structures (from material components to full structure behavior). Most research has focused on the concrete configuration although the timber configuration is also being considered now. It began by considering the mechanical characterization of prestressing steel in both ambient and high temperature.  To date, the project has received over $325,000 from various funding bodies. This funding has largely come from NSERC Canada . Past industrial involvement has included Bridon Steel, ConForce. The project has accumulate in a Book published by Springer, and recent work was  presented at last year’s SIF conference in Princeton New Jersey.

  • Other projects

We are currently Collaborating in research with Queen’s University and Waterloo in Canada. This collaboration considers the behavior of various Glass Fibre Reinforced Polymers (GFRP) reinforcing materials in fire. We are also highly active on the American Society for civil engineers and Canadian society for civil engineers in fire protection. Acting as task group leader for acceptance criterion in the US and chair of the Canadian committee we are actively developing alternative solutions in North America for all construction types.
