Abstract
The shear strength of extruded prestressed precast hollow-core slabs, investigated experimentally and analytically, is reported. Ten slab specimens have been tested, all failing in the shear mode (six in shear tension mode). The analysis explores ways of employing existing procedures for predicting the shear capacity. It is concluded that modification of the FIP recommendations would lead to a better approximation of the test results.
Resume
On rend compte de la résistance au cisaillement de dalles alvéolaires extrudées étudiées expérimentalement et analytiquement. Dix échantillons de dalles ont été essayés, tous à rupture par cisaillement (six par cisaillement en traction). On envisage comment utiliser les modes opératoires existants pour prédire la tenue au cisaillement. On conclut qu'une modification des recommendations FIP permettrait une meilleure approximation des résultats d'essai.
