Long-term behaviour of typical precast, prestressed double T concrete beams made of SCC and ordinary concrete was compared. Increase in deflection under load was registered in both elements for a year. Creep and shrinkage were monitored on laboratory concrete specimens as well. Data shown that concrete elements made of SCC rather than ordinary concrete perform substantially the same.

Abstract
Long-term behaviour of typical precast, prestressed double T concrete beams made of SCC and ordinary concrete was compared. Increase in deflection under load was registered in both elements for a year. Creep and shrinkage were monitored on laboratory concrete specimens as well. Data shown that concrete elements made of SCC rather than ordinary concrete perform substantially the same. Predictions of the long-term behaviour of the concrete structures was made according to different international Codes (Eurocode 2, ACI and JSCE Guidelines for Concrete) and the analytical results compared to the experimental ones.File in questo prodotto:
