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，能够适应新的思想。技术正在快速变化。越来越多的新材料和新系统可用于结构工程应用，为具有知识和创造性技能的工程师提供了大量的可能性。这个职业生涯的建议的目标是促进创新的教学和研究在土木工程。综合教学和研究计划将为新结构以及最先进的维修和改造系统使用非传统材料做出根本性贡献。概述的教学计划将改进本科和研究生阶段基础设施和结构工程领域的课程。这个长期的教育计划直接与PI在土木结构维修和改造层压板领域的研究兴趣相协调。两个创新的课程，一个在结构设计材料，第二个在民用基础设施的维修和改造系统;一套设计为导向的课程重新设计的实验室经验;和一个新的专业集中在结构工程将振兴土木工程专业。工程学的多样性将通过与克拉克森的罗纳德E.麦克奈尔计划。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一活动中受益。本研究将有助于进一步认识环氧树脂粘结FRP层合板与混凝土的界面粘结性能。通过表征界面粘结破坏，可为外贴FRP层合板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所消耗的能量，可以获得断裂力学领域中有价值的信息。特别是，将设计一个新的测试装置，以获得断裂参数。这项研究的结果将直接影响层压板用于土木结构的维修和改造。这项研究将有助于推动层压板和其他新材料进入工程实践的主流，有助于标准设计方程和程序的发展。 作为这个项目的核心成果，PI希望成为一个学术领袖，致力于通过她在教育和研究方面的贡献来加强工程界。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与环境工程系的使命，“通过高质量的本科和研究生课程，教育有才华和有动力的男女成为成功的专业人士，这些课程高度重视学生的访问和与教师的互动。"
