近年来，北美建筑业在中层建筑中使用冷弯型钢（CFS）框架的情况大幅增长。在地震区，CFS框架建筑物利用剪力墙提供主要的侧向抵抗地震引起的荷载。虽然定向刨花板（OSB）和胶合板面板传统上被用作这些基本部件的护套材料，但最近，钢板护套由于其强度、延展性、易于安装和使用不可燃材料等优点而成为一种新的策略。为了解决缺乏数据的CFS框架剪力墙的实际墙线内的建筑物的反应，进行了两个阶段的实验工作。墙线组件的制作和测试与剪力墙放置在重力墙线。剪力墙弦杆组合件包括与多层详图一致的拉杆组件。试件是未完工或完工的，剪力墙在墙线内以对称或不对称的方式布置。此外，I型和II型剪力墙和锚固详细进行了研究。在本文中，测试变量的影响控制的结构详细的CFS框架墙量化通过动态和准静态测试，以及配套文件提出的建筑变化对抗震性能的影响的调查结果。
The North American construction industry has seen substantial growth in the use of cold-formed steel (CFS) framing for midrise buildings in recent years. In seismic zones, CFS-framed buildings utilize shear walls to provide the primary lateral resistance to earthquake induced loads. Although oriented strand board (OSB) and plywood panels have been traditionally used as the sheathing material for these essential components, more recently, steel sheet sheathing has emerged as a novel strategy due to its strength, ductility, ease of installation, and use of noncombustible material, among other benefits. To address the paucity of data regarding CFS-framed shear wall response within actual wall lines of buildings, a two-phased experimental effort was conducted. Wall-line assemblies were fabricated and tested with shear walls placed in-line with gravity walls. The shear walls chord stud packs include tie-rod assemblies consistent with multi-story detailing. Specimens were either unfinished or finished, and the shear walls were laid out in a symmetrical or unsymmetrical fashion within in the wall line. In addition, both Type I and Type II shear wall and anchorage detailing were investigated. In this paper, the impact of test variables governing the structural detailing of CFS-framed walls are quantified through dynamic and quasi-static tests, and a companion paper presents findings regarding the impact of architectural variations on seismic performance.
