1.1 这些测试方法包括横向负载测试，以确定墙段的结构特性。 1.2 这些试验方法用于评估承受垂直于墙体平面施加的横向弯曲载荷的墙板的性能。试验在两点荷载下的水平或垂直试样上进行。还应允许使用安全气囊或真空室施加均匀载荷。根据测试的配置，这些荷载旨在评估墙段的横向挠度、永久变形和最大弯曲承载力或平面剪切承载力，或两者兼而有之。这些试验方法不适用于评估单个结构框架或支撑构件（地板托梁、桥面等），也不适用于两者。墙段垂直构件与周围结构之间的连接不在这些方法的范围内，应采用替代方法进行评估。 1.3 本标准中的注释和脚注提供了解释性材料。这些注释和脚注（不包括表和图中的注释和脚注）不应视为本标准的要求。 1.4 以国际单位制表示的数值应视为标准值。 1.5 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。 1.6 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。 ====意义和用途====== 4.1 这些试验方法中概述的程序用于评估墙体段的挠度、永久变形和最大荷载性能- 横向荷载下的承载能力。基于使用这些程序收集的数据的性能标准不在这些测试方法的范围内。 4.2 横向荷载不能令人满意地应用于某些墙体结构，如砌体，且试样处于水平位置。对于此类结构，应在垂直位置向试样施加荷载，从而模拟使用条件。 4.3 从两点加载获得的测试结果( 8.2.1 和 9.2.1 )和均匀载荷( 8.2.2 和 9.2.2 )既不兼容也不可互换。

1.1 These test methods cover transverse load testing to determine the structural properties of wall segments. 1.2 These test methods serve to evaluate the performance of wall panels subject to transverse bending loads applied perpendicular to the plane of the wall. The tests are conducted on horizontal or vertical specimens under two-point loading. It also shall be permitted to apply uniform load using an air bag or a vacuum chamber. Depending upon the configuration tested, these loads are intended to evaluate the transverse deflection, permanent set, and maximum flexural capacity or planar shear capacity, or both, of the wall segment. These test methods are not intended for the evaluation of individual structural framing or supporting members (floor joist, decking, etc.), or both. The connections between the vertical elements of the wall segment and the surrounding construction are excluded from the scope of these methods and shall be evaluated by alternative means. 1.3 Notes and footnotes in this standard provide explanatory material. These notes and footnotes, excluding those in tables and figures, shall not be considered as requirements of this standard. 1.4 The values stated in SI units are to be regarded as standard. 1.5 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. 1.6 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. ====== Significance And Use ====== 4.1 The procedures outlined in these test methods serve to evaluate the performance of the wall segments for deflection, permanent set, and maximum load-carrying capacity under transverse loading. Performance criteria based on data collected using these procedures fall outside the scope of these test methods. 4.2 Transverse loads cannot be applied satisfactorily to some wall constructions, such as masonry, with the specimen in a horizontal position. For such constructions, the loads shall be applied to the specimen in a vertical position thus simulating service conditions. 4.3 Test results obtained from the two-point loading ( 8.2.1 and 9.2.1 ) and the uniform loading ( 8.2.2 and 9.2.2 ) are neither compatible nor interchangeable.
