New and Ongoing Research Projects: Optimizing ComBAR® applicationsfrom Dritan Topuzi
More projects are considering GFRP reinforcement as an alternative to steel, bringing in the need for continuous research, whether for new applications or optimizing existing ones.
As always, Schöck has continued to invest on further researching ComBAR® properties and applications, collaborating with research institutions in North America as well as Europe.
Some of the ongoing projects, in Canada only, are:
- ComBAR® as shear reinforcement. ComBAR® GFRP reinforced concrete beams are being tested at the University of Waterloo to check the effect of the configuration of shear and flexural reinforcement on their shear strength.
- ComBAR® in compression. Compression behaviour of bare GFRP bars is being investigated at the University of Toronto.
- ComBAR® as prestressed reinforcement. Concrete beams reinforced with prestressed ComBAR® GFRP are being tested at the University of Waterloo. Various parameters are being considered like prestressing force, sustained loading, etc.
- ComBAR® as precast deck reinforcement. Precast concrete decks reinforced with ComBAR are being tested at Ryerson University, to check punching strength, fatigue performance, etc.
- Performance of post-installed ComBAR® bars, glued into sleeves cast in concrete, are being tested at the University of Waterloo. Stage construction is one of the practical applications.
Other research ideas are being investigated, like the use of double headed bars as punching reinforcement, etc.
Schöck remains open to researching new ideas, as well as to providing any necessary information to clients.
