PhD Project:
Fire-safe performance, design, and application of high-performance carbon fibre prestressed concrete structural elements
Current trends in concrete design are forcing the development of more sustainable concrete structures and structural members through careful selection, design, and optimization of both the concrete mixes and the reinforcing materials. Novel structural forms are emerging utilizing high-performance, self-consolidating, fibre-reinforced concrete (HPSCC) reinforced with high-strength, lightweight, and non-corroding prestressed carbon fibre reinforced polymer (CFRP) tendons. One example of this is a new type of precast CFRP pretensioned HPSCC panel. The bond strength reductions in fire, their impacts on the load-bearing capacity of prestressed concrete structures and the spalling behaviour of HPSCC remain largely unknown.The behaviour of these members in fire must be understood before they can be used with confidence. This study will examine the performance of such novel structural forms at high temperature or during exposure to fire, placing particular emphasis on failure modes related to the loss of bond and spalling. This will aid in the elaboration of future design codes taking into account the real capabilities and limitations of these members. This will allow safe use of these advanced materials in real buildings, which in the long term will improve the sustainability, cost-effectiveness, and durability of the built environment.
