Abstract

The tensile strength of the web concrete in prestressed, precast, hollow-core slabs is investigated by direct measurements on specimens separated from the slabs as cast on the production line. The strength thus obtained tends to be relatively low but consistent and an excellent basis for estimating the shear strength of the slabs.

Resume

On examine la résistance en traction de l'âme de dalles alvéolaires en béton précontraint manufacturé par mesures directes sur des échantillons prélevés sur des poutres lors du moulage à la production. La résistance ainsi obtenue tend à être relativement faible, mais néanmoins elle concorde, et offre une excellente base pour estimer la résistance au cisaillement des dalles.
