An experimental campaign on the rupture at the member side of a typical floor-to-beam dry connection for precast structures has been carried out at the laboratory of Politecnico di Milano within the activity of the European Project Safecast. When subjected to horizontal loading, like the seismic action, a strong and stable behaviour of the connection shall be ensured, provided it is properly designed to avoid early brittle ruptures of the concrete edges. The resistance of the concrete side of the connection depends on many factors, among which the reinforcement detailing used in the local part. The experimental investigation regards the behaviour of such portion of the connection reinforced with a typical hooked rebar, studying also the influence of the addition of horizontal stirrups, metallic fibres into the concrete and the presence of pre-stressing tendons.

Abstract

An experimental campaign on the rupture at the member side of a typical floor-to-beam dry connection for precast structures has been carried out at the laboratory of Politecnico di Milano within the activity of the European Project Safecast. When subjected to horizontal loading, like the seismic action, a strong and stable behaviour of the connection shall be ensured, provided it is properly designed to avoid early brittle ruptures of the concrete edges. The resistance of the concrete side of the connection depends on many factors, among which the reinforcement detailing used in the local part. The experimental investigation regards the behaviour of such portion of the connection reinforced with a typical hooked rebar, studying also the influence of the addition of horizontal stirrups, metallic fibres into the concrete and the presence of pre-stressing tendons.
