To successfully meet the challenges of the 21st century, engineers must be creative and be able to adapt themselves to new ideas. Technology is changing at a rapid pace. The increasing number of new materials and new systems available for structural engineering applications offers a large number of possibilities for the engineer with the knowledge and creative skills to understand them. The goal of this CAREER proposal is to promote innovative teaching and research in civil engineering. The integrated teaching and research plans will provide a fundamental contribution to the use of non-traditional materials for new structures as well as for state-of-the-art repair and retrofit systems.The outlined teaching plan will improve the curriculum in the areas of infrastructure and structural engineering both at the undergraduate and graduate levels. This long-term educational plan coordinates directly with the PI's research interest in the area of laminates for repair and retrofit of civil structures. Two innovative courses, one in materials for structural design, the second on repair and retrofit systems for civil infrastructure; a set of redesigned laboratory experiences for design oriented courses; and a new professional concentration in structural engineering will invigorate the profession of civil engineering. Diversity in engineering will be achieved through undergraduate summer research linked to Clarkson's Ronald E. McNair Program. Low-income and first-generation college students, as well as underrepresented minority students will benefit from this activity. The proposed fundamental research will advance the knowledge of interfacial bond behavior between epoxy bonded FRP laminates and concrete. By characterizing the interfacial bond failure, a reliable design procedure can be developed for structural elements strengthened by externally bonded FRP laminates. Valuable information in the area of fracture mechanics will be gained by evaluating the energy dissipated during the interfacial crack growth. In particular, a new test set-up will be designed to obtain a fracture parameter. Results from this research will directly impact the use of laminates for repair and retrofit of civil structures. This research will help to move laminates and other new materials into the mainstream of engineering practice by contributing to the development of standard design equations and procedures. As a central outcome of this project the PI expects to become an academic leader committed to enhance the engineering community through her contributions in education and research. By providing teaching and research of the highest quality, the PI will fulfill the mission of the Department of Civil and Environmental Engineering at Clarkson University to "educate talented and motivated men and women to become successful professionals through quality undergraduate and graduated programs that place high priority on student access and interaction with faculty."

为了成功地迎接21世纪的挑战，工程师必须具有创造性，并能够适应新的想法。技术正在以快速的速度变化。越来越多的新材料和新系统可用于结构工程应用，这为拥有知识和创造性技能的工程师理解它们提供了大量的可能性。这份职业建议书的目标是促进土木工程领域的创新教学和研究。综合的教学和研究计划将为使用非传统材料建造新结构以及最先进的维修和改造系统做出根本贡献。概述的教学计划将改善本科生和研究生水平的基础设施和结构工程领域的课程。这一长期教育计划直接与PI在修复和翻新土木结构的层压板领域的研究兴趣相协调。两个创新课程，一个是结构设计材料，另一个是土木工程基础设施的维修和改造系统；一套重新设计的面向设计的课程的实验室经验；以及结构工程专业的新集中将振兴土木工程专业。工程的多样性将通过与克拉克森的罗纳德·E·麦克奈尔项目相关的本科生暑期研究来实现。低收入和第一代大学生以及代表性不足的少数民族学生将从这项活动中受益。提出的基础性研究将促进对环氧粘结FRP层合板与混凝土界面粘结性能的认识。通过对界面粘结破坏的表征，可以为外贴FRP加固结构构件提供可靠的设计方法。通过计算界面裂纹扩展过程中的能量耗散，将在断裂力学领域获得有价值的信息。特别是，将设计一种新的测试装置来获得断裂参数。这项研究的结果将直接影响层压板在民用结构修复和翻新中的使用。这项研究将有助于将层合板和其他新材料带入工程实践的主流，有助于发展标准的设计方程和程序。作为这一项目的核心成果，PI希望通过她在教育和研究方面的贡献，成为致力于促进工程界发展的学术领袖。通过提供最高质量的教学和研究，PI将履行克拉克森大学土木工程与环境工程系的使命，即“通过高质量的本科和研究生课程，培养有才华和上进心的男性和女性成为成功的专业人员，这些课程高度重视学生的入学机会和与教师的互动。”
