Recycled aggregate concrete (RAC) have been investigated since the late 70’s and the beginning of the 80’s but their use as structural material only recently gained new attention. Several researches have been carried out to investigate their use in conventional reinforced concrete (RC) but very few researches dealt with prestressed concrete (PC) structures. The structural use of RAC is nowadays allowed in many Countries but more stringent limitations exist for its application in prestressing. In the present paper the shortcomings of RAC related to prestressing are put in evidence and evaluated quantitatively by means of deterministic and reliability analysis.

Abstract
Recycled aggregate concrete (RAC) have been investigated since the late 70’s and the beginning of the 80’s but their use as structural material only recently gained new attention. Several researches have been carried out to investigate their use in conventional reinforced concrete (RC) but very few researches dealt with prestressed concrete (PC) structures. The structural use of RAC is nowadays allowed in many Countries but more stringent limitations exist for its application in prestressing. In the present paper the shortcomings of RAC related to prestressing are put in evidence and evaluated quantitatively by means of deterministic and reliability analysis.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
