水平力，如风，被平行于风向的墙壁所抵抗。这些力，位于墙的平面上，被称为剪切或货架荷载，并通过紧固件系统传递给护套。护套材料的鉴定通常仅限于8英尺× 8英尺（2.4米× 2.4米）钉墙组件的性能测试。开发了一种分析程序，可以根据单个紧固件的横向阻力准确地预测机架强度。该结构模型适用于任何护套尺寸或几何形状，因此可以通过简单的侧钉试验或小规模机架试验确定轻型框架墙的机架强度。该程序为设计师和规范官员提供了一种直接的方法来预测包含各种护套材料和紧固件的面板的货架强度。
Horizontal forces, such as wind, are resisted by the walls parallel to the wind direction. These forces, which lie in the plane of the wall, are known as the shear or racking loads, and are transmitted to the sheathing through the fastener system. Qualification of sheathing materials has generally been limited to performance testing of 8-ft by 8-ft (2.4-m by 2.4-m) stud wall assemblies. An analytical procedure has been developed that accurately predicts racking strength based upon the lateral resistance of the individual fasteners. The structural model is applicable to any sheathing size or geometry, so it is possible to determine the racking strength of light frame walls from simple lateral nail tests or small scale racking tests. The procedure offers a direct means for designers and code officials to predict racking strengths of panels incorporating various sheathing materials and fasteners.
