由于与钢相比，纤维增强聚合物（FRP）材料的物理和机械性能有所不同，因此需要对FRP钢筋和层压板采用独特的试验方法。本指南为FRP钢筋和层压板的短期和长期机械、热机械和耐久性试验提供了模型试验方法。美国国家公路与运输协会（ASTM）或美国国家公路与运输协会（AASHTO）预计将采用的部分或全部标准。ACI委员会440发布这些测试方法是为了帮助采用这些方法。推荐的测试方法基于从研究结果和文献综述中获得的全球知识。

Due to differences in the physical and mechanical behavior of fiber-reinforced polymer (FRP) materials compared to steel, unique test methods for FRP bars and laminates are required. This guide provides model test methods for the short- and long-term mechanical, thermo-mechanical, and durability testing of FRP bars and laminates. It is anticipated that these model test methods may be considered, modified, and adopted, either in whole or in part, by a U.S. national standards-writing agency such as ASTM International or AASHTO. The publication of these test methods by ACI Committee 440 is an effort to aid in this adoption. The recommended test methods are based on the knowledge gained worldwide from review of research results and literature.
