Theme 4 (1999-2002):
Innovative Structures with Integrated Sensing
Director: Dr. Sami Rizkalla, University of Manitoba
 PROJECTS IN THEME 4
The research and development of Theme 4 is an evolution of the work proposed in the first phase of ISIS in the area of innovation of civil engineering structures and the use of intelligent sensing for monitoring performance. The innovation includes the use of FRPs in the form of reinforcement bars, and/or prestressing bars and strands for concrete structures. As stated elsewhere, these materials are non corrosive and have a high strength to weight ratio, good fatigue behaviour, low relaxation, electro magnetic neutrality, and easy handling and installation properties.
In this Theme, the use of FRPs is extended to produce a new innovative system which could be ideal for a new generation of bridge girders, hydro poles and the post tensioning of masonry structures. The Theme also proposes to expand the work originally started to use FRPs for smart ground anchorage for concrete dams and slope stability of earth fills. To spread the use of FRPs effectively by industry, topics related to anchorage systems, performance under service loading conditions and durability aspects are also thoroughly investigated to provide a deep understanding of these new materials by engineers since these aspects are essential for the development of design codes.
Innovation also includes new concepts and new products such as the development of the steel free bridge deck technology, a new anchorage system for FRP strands for masonry structures and FRP transmission poles. The work is closely tied to the research and development of integrated FOSs developed by Theme 2 as well as the remote monitoring implemented in field applications by Theme 3.
The research in Project T4.2, Engineered Fibre Reinforced Cement based Composites for Bridge Decks, has been completed and, therefore, no funds have been allocated in the second phase of ISIS Canada.
Over the long term, the impact of Theme 4 research on Canadian infrastructure design and construction is destined to be huge. The potential savings and economic benefits could be unprecedented in this field. A national infrastructure network which lasts much longer and requires less maintenance will undoubtedly have a positive impact on the Canadian economy. In the process, social benefits are likely to unfold, because funds which were previously devoted to infrastructure will be free for other uses, such as social programs.
