The evaluation of the response of cold-formed steel (CFS) drywall partitions under in-plane earthquake loading is one of the open tasks for understanding the impact of nonstructural elements on the seismic performance of constructions, especially when the implementation of performance-based earthquake criteria is required. In this context, the evaluation of the seismic demand on fasteners connecting drywall partitions with the surrounding structures has not been well covered. To overcome this gap, a specific experimental study devoted to evaluate the in-plane seismic demand on power actuated fasteners (PAF) connecting CFS drywall partitions and concrete surrounding elements is presented in this paper. In particular, the experimental activity includes seven quasi-static reversed cyclic tests on full-scale drywall partitions. Parameters under investigation are: type of surrounding connections; type of sliding connection; spacing of PAFs. From global point of view, results showed that the main parameter affecting the seismic response of the drywall partitions was the type of surrounding connections. PAFs connecting both studs and tracks to concrete surrounding elements exhibited elastic behaviour without significant damage in all tested walls with seismic demand equal to 0.50 mm in terms of displacement, 1.9 kN in terms of force per single PAF, 4 kN/m in terms of force per unit length of the wall. Therefore, with reference to the design process, for typical single stud drywall partitions having common high of about 2.6 m sheathed on both faces with two layers of 12.5 mm thick standard gypsum wall boards fixed to the steel frame with self-piercing screws (spacing of 1000 and 250 mm on the centre for the interior and exterior panels, respectively), in which connections between wall and surrounding elements are made of Hilti X-X PAFs spaced in the range from 300 to 500 mm, the PAFs exhibited an elastic behaviour resulting over-strength elements in all studied conditions.

冷弯型钢（CFS）干式墙隔断在面内地震荷载下的响应评估是了解非结构元素对建筑物抗震性能影响的开放任务之一，特别是在实施基于性能的地震时需要标准。在这种情况下，对连接干墙隔断与周围结构的紧固件的抗震需求的评估尚未得到很好的涵盖。为了克服这一差距，本文提出了一项具体的实验研究，致力于评估连接 CFS 干墙隔断和混凝土周围构件的动力驱动紧固件 (PAF) 的面内地震需求。特别是，实验活动包括对全尺寸干墙隔断进行七次准静态反向循环测试。调查的参数有： 周围连接的类型；滑动连接类型；PAF 的间距。从全局角度来看，结果表明，影响干墙隔断地震响应的主要参数是周围连接的类型。将螺柱和轨道连接到混凝土周围元件的 PAF 在所有测试的墙壁中都表现出弹性行为，没有明显损坏，地震要求位移等于 0.50 mm，每个 PAF 的力等于 1.9 kN，力等于 4 kN/m墙的每单位长度。因此，参考设计流程，对于一般高约2.6m的典型单龙骨干墙隔断，两面均套有两层12.5mm厚的标准石膏墙板，用自冲螺钉固定在钢架上（间距为内部和外部面板的中心分别为 1000 和 250 毫米），其中墙壁和周围元件之间的连接由间隔在 300 至 500 毫米范围内的喜利得 XX PAF 制成，PAF 表现出弹性行为，导致过度所有研究条件下的强度要素。
