Effect of cyclic loading protocols on the experimental seismic performance evaluation of suspended piping restraint installations

Suspended non-structural elements, such as water and sprinkler piping systems, are key to the functionality of important facilities, such as hospitals and schools. Recent earthquakes have demonstrated the vulnerability of these systems, particularly for those that were inadequately restrained. Seismic qualification requirements of non-structural elements contained in recent building codes and industry standards rely on experimental procedures, …
