缺乏一个全面的，有效的，易于访问的数据库的纤维增强聚合物（FRP）复合材料的耐久性有关的民用基础设施的应用已被确定为一个关键的障碍，这些材料的广泛接受的结构设计师和土木工程师。强调这一问题是因为感兴趣的结构主要是承重的，并且预计将在较长的时间内保持使用，而无需进行大量的检查或维护。本文简要介绍了在土木工程研究基金会和联邦公路管理局的主持下进行的差距分析研究，以确定和优先考虑耐久性数据的关键差距。该研究的重点是FRP在内部加固，外部加固，抗震改造，桥面，结构型材和面板中的使用。感兴趣的环境是水分/溶液、碱度、蠕变/松弛、疲劳、火灾、热效应（包括冻融）和紫外线暴露。
The lack of a comprehensive, validated, and easily accessible data base for the durability of fiber-reinforced polymer (FRP) composites as related to civil infrastructure applications has been identified as a critical barrier to widespread acceptance of these materials by structural designers and civil engineers. This concern is emphasized since the structures of interest are primarily load bearing and are expected to remain in service over extended periods of time without significant inspection or maintenance. This paper presents a synopsis of a gap analysis study undertaken under the aegis of the Civil Engineering Research Foundation and the Federal Highway Administration to identify and prioritize critical gaps in durability data. The study focuses on the use of FRP in internal reinforcement, external strengthening, seismic retrofit, bridge decks, structural profiles, and panels. Environments of interest are moisture/solution, alkalinity, creep/relaxation, fatigue, fire, thermal effects (including freeze-thaw), and ultraviolet exposure.
