Abstract

Optimized, high-performance concrete elements, prestressed with carbon fibre reinforced polymer (CFRP) tendons offer great potential within the sustainable modern built environment. However, the performance of these elements in fire is not well known and must be better understood for applications where fire resistance is required. Findings from large-scale fire resistance tests on thin CFRP prestressed concrete slabs are presented and discussed. Results show that explosive spalling in fire results in sudden collapse, and when spalling is avoided failure occurs by loss of anchorage, which is in turn governed by the temperature of the tendons.
