- •
Beams exposed to 500 °C and repaired with NSM-CFRP recovered their load capacity.
- •
Beams exposed to 600 °C and repaired with NSM-CFRP did not recover their load capacity.
- •
Lower CFRP strips’ spacing contributed to a higher recovery in mechanical properties.
- •
Flexural stiffness for heat-damaged and repaired beams was not recovered.
- •
Toughness and ductility for heat-damaged and repaired beams were improved.
