AbstractThe objective of the proposed Workshop to be held in Varenna, Italy, is to analyze the recent advances in fiber reinforced concrete materials and their applications for civil infrastructure systems in Italy and the United States, and identify potential new research areas. The Workshop will focus on materials properties, forms of deterioration and their effects on structural performance, and quantitative analysis of materials. Emphasis is placed on further basic research needed before this advanced technology can be transferred to professional practice. The main inhibitor to the application of this technology in engineering practice, both in Europe and the United States, is the lack of appropriate codes and standards as well as governmental certification. ACI and RILEM have already undertaken major efforts to refine design methodologies. The important next step would be to identify the research that needs to be done. Also, the most expedient ways need to be explored on how to use fiber reinforcement either as partial replacement of conventional steel reinforcement and in special cases to completely replace such conventional reinforcement. Advances in the technology will be discussed that document the performance of concrete structures with greatly reduced or no conventional steel reinforcement at all.The intellectual merit of the proposed workshop derives from the international cross-fertilization it makes possible. Both the European and American participants have made significant advances in recent years, and it will benefit both sides if an exchange of information is made possible in the productive setting of a workshop. The outcome of the workshop has the potential of a significant impact, because engineering practitioners are eager to use this new technology and apply it to improve the performance of infrastructure facilities worldwide at potentially reduced cost.

在意大利Varenna举办的研讨会的目的是分析纤维增强混凝土材料及其在意大利和美国民用基础设施系统中的应用的最新进展，并确定潜在的新研究领域。该讲习班将侧重于材料的性质，退化形式及其对结构性能的影响，以及材料的定量分析。重点放在进一步的基础研究之前，这种先进的技术可以转移到专业实践。在欧洲和美国，这一技术在工程实践中应用的主要障碍是缺乏适当的规范和标准以及政府认证。ACI和RILEM已经做出重大努力来完善设计方法。重要的下一步是确定需要进行的研究。此外，需要探索如何使用纤维增强作为传统钢筋的部分替代以及在特殊情况下完全替代这种传统钢筋的最有利的方法。将讨论技术的进展，记录混凝土结构的性能大大减少或根本没有传统的钢筋。拟议的研讨会的智力价值来自国际交流，它使之成为可能。近年来，欧洲和美国的参与者都取得了重大进展，如果能够在研讨会的富有成效的环境中交流信息，将使双方受益。研讨会的成果有可能产生重大影响，因为工程从业人员渴望使用这一新技术，并将其应用于以可能降低的成本改善世界各地基础设施的性能。
