作为非结构构件测试系列的第一部分，室内干墙隔墙被选为实验项目。该测试系列将涵盖在地震荷载下对建筑物经济损失有重大影响的非结构部件，即内部干墙隔墙、外部覆层和窗玻璃以及天花板。四个全尺寸的干墙分区与轻钢龙骨框架进行了测试，以观察在循环荷载条件下的损坏。研究了门和交叉墙对干墙隔墙性能的影响。损坏集中在石膏板与天花板、地板或柱子接触的周边区域。动态加载并没有放大从准静态测试中观察到的干墙分区上的损坏。损伤-维修费用关系表明，在2%的层间角位移下，维修费用几乎达到初始费用。版权所有© 2006约翰威利父子有限公司。
As the first part of non‐structural component test series, interior drywall partitions are selected for an experimental program. This test series will cover non‐structural components that are significant in the economic losses in buildings subjected to seismic loading, namely interior drywall partitions, exterior cladding and window glasses, and ceilings. Four full‐scale drywall partitions with light‐gage steel stud framing were tested to observe damage in cyclic loading conditions. Effects of a door and an intersecting wall on the behaviour of drywall partition are studied. Damage was concentrated to perimeter regions where gypsum boards made contacts with ceiling, floor, or columns. Dynamic loading did not amplify the damage on a drywall partition over the damage observed from the quasi‐static test. Damage–repair cost relationships show that the repair cost reaches almost the initial cost under 2% radian interstorey drift. Copyright © 2006 John Wiley & Sons, Ltd.
