NATIONAL SCIENCE FOUNDATIONProposal AbstractProposal: 1559540 PI Name: Erdogmus, Ece Proposal Title: U.S.-Turkey Research Collaboration in Conservation EngineeringInstitution: University of Nebraska-Lincoln (Omaha Campus)Abstract Date: 03/24/16Rehabilitation of historical/existing structures is an area ripe for research. With an increasing number of aging structures in the United States, there is a growing need for workforce development to address the potential for historic preservation in coming years. The goal of this project is to develop a cadre of experts with specialized training and global awareness in the engineering aspects of historical preservation projects. To address this need, Dr. Erdogmus from the University of Nebraska-Lincoln will collaborate with the Izmir Institute of Technology (IZTECH) of Turkey. This 3-year program will bring a group of nine US students to Turkey for a seven-week summer research in historic preservation engineering. It is the intention of the PI to recruit at least 50% of the cohort each year from underrepresented groups. The Turkish mentors from IZTECH are Dr. Mine Turan and Dr. Engin Aktas, representing the Architectural Restoration and Civil Engineering Departments, respectively. Under the experienced leadership of the hosts and the PI, the US students participating in the program will be provided with meaningful and comprehensive research experiences comprised of lab-work at IZTECH campus and a variety of field-applications that involve historical sites. This three year U.S.-Turkey IRES program will involve American graduate and undergraduate students in research projects at the interface of structural engineering and conservation with three focus themes: 1) Engineering- conservation coordination for assessment of historical structures and materials prior to an intervention, 2) Engineering- conservation coordination for the development of compatible materials for historical retrofits, and 3) Post-Intervention assessment and risk analysis for the collapse-safety of structures. Under each of these focus themes, the IRES students will conduct specific projects and tasks; namely, the students will: a) Develop a novel method to provide a closed feedback loop on complex sites, which involves a nondestructive evaluation (NDE) based rating system for each element correlating the visual assessments to its interior damage levels. This will then inform variant constitutive models and aid in the design for the conservation intervention. b) Investigate chemical and mechanical properties of modern cements from different locations in order to evaluate their behavior under extreme heat, salt water, and freeze-thaw cycles when paired with different historical stones. c) Develop a decision making algorithm for historical structures using probabilistic assessments and sensitivity analyses to identify safety concerns and to predict design event recurrence intervals for which a given structure remains safe. This algorithm will then support decisions for or against intervention, ensuring only a minimum level of invasive intervention applied to the historic site. This work is funded by the IRES program of NSF Office of International Science and Engineering (OISE).

国家科学基金会提案摘要提案：1559540 PI 姓名：Erdogmus, Ece 提案标题：美国-土耳其保护工程研究合作机构：内布拉斯加大学林肯分校（奥马哈校区）摘要日期：2016 年 3 月 24 日修复历史/现有结构是一个成熟的研究领域。 随着美国老化建筑数量的增加，对劳动力发展的需求日益增长，以解决未来几年历史保护的潜力。 该项目的目标是培养一支在历史保护项目工程方面受过专门培训并具有全球意识的专家队伍。 为了满足这一需求，内布拉斯加大学林肯分校的 Erdogmus 博士将与土耳其伊兹密尔理工学院 (IZTECH) 合作。 这个为期三年的项目将带领九名美国学生前往土耳其进行为期七周的历史保护工程夏季研究。 PI 的目的是每年从代表性不足的群体中招募至少 50% 的人员。 IZTECH 的土耳其导师是 Mine Turan 博士和 Engin Aktas 博士，分别代表建筑修复系和土木工程系。 在主办方和 PI 经验丰富的领导下，参与该项目的美国学生将获得有意义且全面的研究经验，包括 IZTECH 校园的实验室工作和涉及历史遗址的各种现场应用。这个为期三年的美国-土耳其 IRES 项目将让美国研究生和本科生参与结构工程和保护领域的研究项目，重点关注三个主题：1) 工程-保护协调，用于在干预前评估历史结构和材料；2) 工程-保护协调，用于开发历史改造的兼容材料；3) 干预后评估和结构倒塌安全的风险分析。在每个重点主题下，IRES 学生将开展具体的项目和任务；即，学生将： a) 开发一种新颖的方法，在复杂场地上提供闭合反馈循环，其中涉及针对每个元素的基于无损评估 (NDE) 的评级系统，将视觉评估与其内部损坏级别相关联。 这将为不同的本构模型提供信息，并有助于保护干预的设计。 b) 研究来自不同地点的现代水泥的化学和机械性能，以评估它们与不同历史石材搭配时在极端高温、盐水和冻融循环下的行为。 c) 使用概率评估和敏感性分析为历史结构开发决策算法，以识别安全问题并预测给定结构保持安全的设计事件复发间隔。然后，该算法将支持支持或反对干预的决策，确保仅对历史遗址进行最低水平的侵入性干预。这项工作由 NSF 国际科学与工程办公室 (OISE) 的 IRES 项目资助。
