The article reviews the state of the art in active confinement of RC columns using shape memory alloys (SMA). The previous research in this area showed that confinement with SMAhad a positive effect on the deformability and capacity of the elements. In conclusion, future research directions were identified for the influence of concrete strength and reinforcement ratio, the anchoring method of SMA reinforcement, SMA relaxation, and the column slenderness on the effectiveness of the method.

Artykuł stanowi przegląd stanu wiedzy dotyczącej aktywnego skrępowania słupów żelbetowych przy użyciu materiałów z pamięcią kształtu (SMA– z ang. Shape Memory Alloy). Wcześniejsze badania wykazały, że skrępowanie przez SMA wpłynęło pozytywnie na odkształcalność i nośność elementów. W podsumowaniu wskazano kierunki dalszych badań dotyczących wpływu wytrzymałości betonu i stopnia zbrojenia, sposobu kotwienia zbrojenia SMA, relaksacji SMA, a także wpływu smukłości słupów na efektywność metody.
