The lack of availability of design guidelines and technical data for the use of carbon fiber reinforced polymer (CFRP) reinforcements has contributed significantly to the delay in using composites materials in prestressed concrete bridges in the US. Consequently, no single prestressed concrete bridge using CFRP has been constructed or even considered by any government agency. As a result, the use of CFRP reinforcements in the US has been limited to research activities and subsequent technical publications. The proposed research program is tailored to develop design guidelines to aid the designers to safely desin CFRP prestressed structural components, and to construct a one-half scale bridge model and two prestressed concrete girders and test them under different loading conditions. The proposed investigation will result in technical data that will be adopted in the construction of the first authorized CFRP prestressed concrete bridge inn the US. Furthermore, future prestressed concrete bridge projects that will be undertaken by the supporting state agencies will benefit signigicantly from the generated data.

由于缺乏碳纤维增强聚合物（CFRP）加固材料的设计指南和技术数据，导致美国在预应力混凝土桥梁中使用复合材料的延迟。因此，没有任何一座预应力混凝土桥梁使用CFRP，甚至没有任何政府机构考虑使用CFRP。因此，CFRP加固材料在美国的使用仅限于研究活动和随后的技术出版物。建议的研究计划是量身定制的发展设计准则，以帮助设计人员安全desin CFRP预应力结构部件，并构建一个半比例的桥梁模型和两个预应力混凝土梁，并测试他们在不同的加载条件下。拟议的调查将导致技术数据，将采用在美国第一个授权的CFRP预应力混凝土桥梁的建设。此外，支持国家机构将承担的未来预应力混凝土桥梁项目将从生成的数据中受益匪浅。
