CAREER: Repair and Retrofit Systems for Civil Infrastructure

为了成功地迎接21世纪的挑战，工程师必须具有创造力，并能够适应新的想法。科技日新月异。用于结构工程应用的新材料和新系统的数量不断增加，为具有知识和创造性技能的工程师提供了大量的可能性来理解它们。本职业建议的目标是促进土木工程的创新教学和研究。综合教学和研究计划将为新结构使用非传统材料以及最先进的维修和改造系统提供基础贡献。大纲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与PI在土木结构修复和改造层压板领域的研究兴趣直接协调。两门创新课程，一门是结构设计材料，另一门是民用基础设施的维修和改造系统；设计导向课程的一套重新设计的实验体验；结构工程这一新的专业重心将为土木工程专业注入新的活力。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，以及少数族裔学生将从这项活动中受益。所提出的基础研究将促进对环氧复合玻璃钢层合板与混凝土之间界面粘合行为的认识。通过对界面粘结破坏的表征，可以为外粘结FRP层合板加固结构单元制定可靠的设计程序。通过计算界面裂纹扩展过程中的能量耗散，可以获得断裂力学领域中有价值的信息。特别是，将设计一种新的测试装置来获得断裂参数。本研究的结果将直接影响层压板在土木结构修复和改造中的应用。这项研究将有助于通过标准设计方程和程序的发展，将层压板和其他新材料推向工程实践的主流。作为该项目的核心成果，PI希望通过她在教育和研究方面的贡献，成为致力于加强工程界的学术领袖。通过提供最高质量的教学和研究，PI将完成克拉克森大学土木与环境工程系的使命，即“通过高质量的本科和研究生课程，高度重视学生的接触和与教师的互动，教育有才华、有动力的男女成为成功的专业人士。”

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."
