1.1 本规程描述了评估框架墙典型截面抗剪承载力的方法，框架墙支撑在刚性基础上，荷载沿着刚性支架相对的边缘施加在墙体平面内，并沿着与刚性支架平行的方向施加。目的是确定用作刚性支架上剪力墙的任何结构轻型框架墙配置的剪切刚度和强度。 1.2 限制- 本规程不作为分类护套抗剪能力的依据，也不作为评估墙体在柔性基础上加载时产生的组合弯曲和剪切的依据。 1.2.1 通过保持所有其他变量不变来评估护套变化的影响。然而，框架结构和边界条件的允许变化需要准确记录测试设置，以验证护套对墙体抗剪能力贡献的跨研究比较。 注1: 按照此做法，通过将剪切刚度和强度结果与在刚性基础上测试的相同墙体的剪切刚度和强度结果进行比较，来评估在柔性基础上测试的墙体。然而，没有给出测量墙体弯曲位移或评估由基础弯曲引起的应力分布的方法。 从本规程规定的基础条件到柔性条件的墙体开裂行为的任何外推，应在代表性基础上进行对比试验。 1.3 以国际单位制表示的数值应视为标准值。括号中给出的值是英寸-磅单位的数学转换，仅供参考，不被视为标准值。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This practice describes methods for evaluating the shear capacity of a typical section of a framed wall, supported on a rigid foundation and having load applied in the plane of the wall along the edge opposite the rigid support and in a direction parallel to it. The objective is to provide a determination of the shear stiffness and strength of any structural light-frame wall configuration to be used as a shear-wall on a rigid support. 1.2 Limitations— This practice is not intended to be used as a basis for classifying sheathing shear capacity or as an evaluation of combined flexure and shear resulting from the wall being loaded on a flexible foundation. 1.2.1 The effect of sheathing variations is assessed by holding all other variables constant. Permitted variations in framing configuration and boundary conditions, however, require accurate documentation of the test setup to validate across-study comparisons of sheathing contribution to wall shear capacity. Note 1: A wall tested on a flexible foundation is evaluated by comparing shear stiffness and strength results to those of an identical wall tested on a rigid foundation, following this practice. However, no methods are given for the measurement of wall bending displacements or assessment of stress distribution resulting from foundation flexure. Any extrapolation of wall racking behavior from the foundation conditions specified by this practice to flexible conditions shall be done with the support of a comparative test on a representative foundation. 1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
