Abstract

The results considered are the experimental research of behavior of the Hilti energy-saving ventilated facade system with the hidden clips fastening of natural stone finishing slabs on an aluminum elements framework. The sample of the facade system part with dimensions of 4 × 2 m was tested on a stand in a horizontal position for the complex action of its dead weight, icing and wind due to the operational and boundary, positive and negative design loads, in ordinary and corner areas of the building. The load calculations, test equipment, test schemes and measuring instruments layouts were specified. The physical and mechanical characteristics of finishing slabs natural stone were determined. The finishing of the tested sample consisted of 4 plates with dimensions of 2035 × 890 × 30 mm and weight of 122.5 kg. The values of finishing deformations were determined, and their exhaustive analysis was
presented. The destructive load in the slabs plane was 46.6 kN and corresponded to the building height of 27 m. The sample destruction was characterized by
the deformations of clips with the vertical movement and connection failure of the guiding and supporting clips profiles. The finishing slabs chemical anchors
withstood the negative wind pullout load of 0.652 kN and the vertical shear load of 1.664 kN without any damage. The tests of the sample of facade system
part showed that the system withstood all designed types of operational and boundary loads from its dead weight, finishing bilateral icing, as well as positive and negative wind loads in ordinary and corner areas. During the design, installation, and operation of this facade system its vulnerabilities should be taken into account including the finishing massiveness, reliability of connections between the supporting and clip frame profiles as well as clips themselves, the possibility of structural protection against icing of horizontal gaps between the floor slabs.
