Cyclic Performance of a Precast Beam-Panel Joint Device
摘要
The recent earthquake of Amatrice in 2016 had a huge impact on both historical and recent buildings, underlining the needs of strengthening interventions against cyclic actions. Not just masonry buildings suffered the earthquake intensity but even precast industrial buildings showed local damages or even structural failure. For this type of constructions, a possible strengthening intervention is represented by the installation of anti-seismic connection devices. Depending on the connected elements and the device features, several improvements can be obtained. For instance, one of the issues in precast industrial buildings is represented by the cladding system, which is typically made by reinforced concrete panels with significant dimensions. In this paper, an experimental campaign on the cyclic response of a precast beam-panel joint device is proposed, evidencing its performance in cyclic tests and its capability in uncoupling the in-plane cladding system motion compared to the structural motion.
