A conventional approach used in current building practice to minimize panel-structure interaction is to slacken its connections to make the panel slide relative to the structural
skeleton, rather than to force excessive and unfeasible load transfer in the connections. Nevertheless, this solution is effective only for relatively small values of drifts of
about 1% because of the small strokes provided by these connection devices that, in the majority of the cases, are not specifically designed to accommodate large seismic displacement demands. Even if different cladding solutions may require different design recommendations on the basis of different capacities of their connection components and of different levels of interaction with the supporting structure, the safest design methodology is to impose the 1% interstory drift as a conventional limit to design the cladding system and skeletal frame, as prescribed by the current Italian seismic code24 and shown by the experimental program conducted, thus implicitly accepting a pseudoelastic structural response for this type of precast concrete
building.
