Friction-based dissipative devices for precast concrete panels
HighlightsA novel panel-to-panel dissipative device for precast structures is proposed.Tests on single devices allowed to investigate several technological issues.Sub-assembly tests showed a correct performance of devices installed within panels.Tests on a full-scale prototype confirmed the seismic effectiveness of the device.Design rules of the dissipative device have been proposed.
AbstractThe stability of precast concrete wall panels under seismic action can be ensured by means of dissipative systems of panel-to-panel connections that allow to control the level of forces and limit the displacements. This paper deals with a connection system consisting of friction-based devices inserted into appropriate recesses within the joints between vertical or horizontal panels. The results of experimental tests carried out on single connectors, as well as on structural sub-assemblies consisting of two full scale panels, are presented. The technological choices of materials and components that ensure a stable hysteretic behaviour of the devices are discussed. The effectiveness of the devices in improving the seismic performance of precast buildings under seismic action is also shown based on the results of cyclic and pseudo-dynamic tests on full-scale structural prototypes.
