CRACKING ANALYSIS OF PRECAST – IN SITU REINFORCED CONCRETE SLAB WITH PLASTIC VOID FORMERS
In this article results of experimental and numerical analysis of precast – in situ reinforced concrete slab with plastic void formers are discussed. Slab is composed of precast and in situ concrete layers. Voids are formed inside the slab using spherical plastic void formers. Slab cracking pattern is determined by numerical analysis. Cracking pattern acquired by numerical analysis is compared to cracking pattern determined by experimental study. Shear stiffness in the bond between precast and in situ concrete layers was specified when numerical model was built.
