Investigations on Fibre Reinforced Polymers (FRPs) at ambient temperature have already proved their effectiveness as an internal reinforcement as an alternative to traditional steel reinforcement because of their high mechanical performance and durability. However, their performance at elevated and high temperatures requires proper understanding to enable safe design methods, as FRPs are highly vulnerable even to remotely elevated temperatures. In addition, aspects related to the thermal conductivity and combustibility should be carefully considered. This article aims to present up-to-date research on reduced-scale and full-scale investigations of internally FRP-reinforced concrete structural elements as well as conclusions on the directions of further research. In terms of mechanical performance, post-heated tests and simultaneous thermo-mechanical loading (at transient and steady states) were analysed.

Badania dotyczące kompozytów z polimerów wzmacnianych włóknem (ang. Fibre Reinforced Polymer) w temperaturze pokojowej wykazały ich efektywność jako wewnętrznego zbrojenia jako alternatywę dla tradycyjnego zbrojenia stalowego dzięki swoim wysokim parametrom mechanicznym i trwałości. Jednakże, ich zachowanie w podwyższonych i wysokich temperaturach wymaga wciąż odpowiedniego zrozumienia, aby umożliwić bezpieczne metody projektowania, ponieważ FRP są bardzo wrażliwe nawet na nieznacznie podwyższone temperatury. Ponadto należy dokładnie rozważyć aspekty związane z przewodnością cieplną i palnością. Artykuł ma na celu przedstawienie aktualnego przeglądu stanu wiedzy dotyczącego badań w skali zredukowanej oraz pełnoskalowych elementów konstrukcyjnych betonowych z wewnętrznym zbrojeniem FRP oraz wnioski dotyczące kierunków dalszych badań. Pod kątem parametrów mechanicznych przeanalizowano wyniki badań po wygrzewaniu oraz pod wpływem jednoczesnego obciążenia termomechanicznego (w stanach nieustalonym i ustalonym).
