Composite action of precast hollow core slabs with
structural topping

Abstrakt

There is no interface reinforcement in composite floors made of HC slabs covered with structural topping. In such structures, the preparation of the top surface of the precast element has a major influence on longitudinal shear strength. The recommendations of various codes concerning the bearing capacity of the non-reinforced joint in concrete composite structures are presented in this paper. The results of the authors’ own computational analysis have been compared with the results of experimental tests carried out by different research institutions. Calculations according to Eurocode 2 underrate the value of the bearing capacity. A much stronger conformity of the results was achieved for the calculations carried out according to previously existing standards or according to information given in Model Code 2010.
