Fire resistance of concrete structures containing advanced materials

North American infrastructure is crumbling. Media reports of dramatic fires, structurally unsafe buildings and failed bridges are becoming more frequent. Many concrete structures are in urgent need of repair or rehabilitation, yet the current economic crisis demands that we develop innovative materials and cost-effective techniques for repair. Unfortunately, there is insufficient and inadequate information regarding the performance of these repaired structures in fire; especially when new materials are used for repair. For buildings or parking garages, fire resistance is a vital concern to protect public safety as evidenced by tragic events such as the World Trade Center disaster, and dramatic building collapses due to fire in Spain and the Netherlands. Thus, the overall aim of the proposed research is to obtain an understanding of the behaviour of rehabilitated concrete structures in fire. The research will ultimately aim to evaluate how fire impacts buildings as a whole, rather than the behaviour of individual parts.
