Abstract: Recent earthquakes highlighted the inadequacy of the current design criteria for the connection system of the cladding wall panels of precast buildings. A systematic solution to this problem consists in realising an isostatic panel-to-structure connection system that allows a seismic response of the frame structure with no reaction forces into the connections of the panels. This can be achieved by supporting each panel to the structure with two hinges, one at the top and one at the bottom, so to have a pure frame behaviour with a rigid-body motion of the pendulum arrangement of panels. However, the silicone sealant needed in between the joints can provide a certain degree of contrast to the pendulum motion. In order to quantify this contribution, a series of experimental tests has been carried out on both small assemblages of concrete blocks jointed with silicone strips and structural sub-assembly made by two full scale cladding panels with pendulum arrangement. This paper presents the results of the experimental tests and provides specific considerations about the possible influence of silicone joints on the seismic response of the frame-panel structural assembly.
