The recent emergence of masonry as an engineered construction material in the same class as concrete and steel has not been matched by equal advancements in standard test procedures for masonry. Existing test procedures do not or are marginal in meeting today's needs and will be grossly inadequate for needs associated with future limit state design for masonry. The U.S. Coordinated Program for Masonry Research as well as other NSF funded research has developed a broad database on the static and earthquake response of masonry especially reinforced masonry. This research project uses these data to recommend needed improvements to masonry testing standards. The research establishes specific needs that masonry tests must fulfill both for current needs and for future needs associated with limit state design, critically reviews the ability of existing tests to meet these needs, it develops required modifications to existing tests, and it develops new tests where existing tests are lacking. The result of this study is a set of carefully documented recommendations for test standard modifications or additions applicable to earthquake and static behavior of structures. These recommendations provide the technical base to support actions by others or by standard writing bodies.

最近，砌体作为一种与混凝土和钢材同等级别的工程建筑材料出现，但砌体标准测试程序的进步却未能与之相匹配。现有的测试程序不能或不足以满足当今的需求，并且将严重不足以满足与未来砖石极限状态设计相关的需求。美国砖石研究协调计划以及其他 NSF 资助的研究开发了一个关于砖石尤其是加固砖石的静态和地震响应的广泛数据库。该研究项目使用这些数据来建议砌体测试标准所需的改进。该研究确定了砌体测试必须满足当前需求和与极限状态设计相关的未来需求的特定需求，严格审查现有测试满足这些需求的能力，对现有测试进行必要的修改，并在现有测试缺乏的地方开发新测试。这项研究的结果是一套仔细记录的建议，用于适用于结构的地震和静态行为的测试标准修改或添加。这些建议为支持其他人或标准编写机构的行动提供了技术基础。
