Abstract
This paper examines the influence of two reversed cyclic loading protocols on the response of gypsum light-gauge metal-stud partition walls, which are common in office, hotel, and laboratory buildings. Two identical full-scale three-dimensional specimens were constructed to represent a typical room in an office building. The specimens were tested quasi-statically along two axes using different loading protocols. The loading protocols were applied to observe the sensitivity of loading protocol on damage progression. The loading protocols were developed for the Applied Technology Council ATC-58 project published in FEMA 461, which, among others, addresses the racking protocol of nonstructural building components for use within a performance-based earthquake engineering framework. Details are given about the damage progression of the specimens to the loading protocols and their lateral force-displacement response characteristics.
