进行了一项独特的全面研究，以考虑石膏板隔墙和典型吊顶系统的行为。每个样本由四个隔墙组成，形成一个封闭的空间，并允许相互垂直的墙壁相互作用，以进行评估。通过在其中一面墙中放置一个大开口和在另一面墙中放置一个门框，研究了隔墙中不连续性的影响。该设置还允许评估墙壁和天花板系统之间的相互作用。通过使用振动台加载试样，使得行为和损伤可以与特定的漂移水平相关联。由于存在垂直墙，非结构墙发生摇摆行为。当漂移水平达到1/66弧度时，可以看到严重的损坏，其中大部分损坏集中在门框周围和隔墙的角落。天花板系统只受到最小的损坏，因为它们符合设计标准。该试验的结果对于在日本E-defense试验的四层钢框架的全尺寸研究提供初步数据至关重要，该框架包含这些非结构系统。
A unique full-scale study was undertaken to consider the behavior of gypsum board partition walls and typical suspended ceiling systems. Each specimen consisted of four partition walls which created an enclosed space and allowed for the interaction of perpendicular walls framed into each other to be evaluated. The effects of discontinuities in the partition walls were studied through the placement of a large opening in one of the walls and a door frame in the opposite wall. The setup also allowed for the evaluation of interaction between the walls and ceiling system. The specimens were loaded through the use of a shake table such that the behavior and damage could be correlated with particular drift levels. The non-structural walls underwent a rocking behavior as a result of the presence of a perpendicular wall. Significant damage was seen as drift levels reached 1/66 radians with most of this damage concentrated around the door frame and at the corners of the partition walls. Only minimal damage was imparted to the ceiling systems as they performed to design standards. The results of this test were critical in providing preliminary data for the full-scale study of a four-story steel moment frame tested at E-defense in Japan, which incorporated these non-structural systems.
