International Workshop on Advanced Fiber Reinforced Concrete; September 24-25, 2004; Milan, Italy

摘要本次研讨会将在意大利瓦雷纳举行，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。讲习班将侧重于材料的特性、劣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，这种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已经在改进设计方法方面作出了重大努力。重要的下一步是确定需要进行的研究。此外，如何使用纤维增强材料部分替代传统钢筋，在特殊情况下完全替代传统钢筋，也需要探索最方便的方法。将讨论技术的进步，记录混凝土结构的性能，大大减少或没有传统的钢筋加固。拟议的讲习班的智力价值源于它使国际交流成为可能。欧洲和美国的与会者近年来都取得了重大进展，如果能够在讲习班富有成效的环境中交换资料，对双方都有好处。研讨会的成果具有潜在的重大影响，因为工程从业者渴望使用这项新技术，并将其应用于在潜在的降低成本的情况下改善全球基础设施的性能。

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.
