Abstract

This work is motivated by the need to investigate the cyclic load response of restrained (via anchorage or other) nonstructural components and systems (NCSs). For this purpose, a load protocol is developed for capturing the behavior of the restraining element when subjected to seismic loading. The protocol incorporates numerical analyses of buildings designed to respond nonlinearly under design earthquake events, analysis of secondary systems located in these buildings and rainflow counting of time history results extracted from these analyses. Secondary system response results are used to develop tension and shear load protocols. Protocol statistics are presented and envisioned to be useful in anchor or other restraint system qualification tests.
