该提案要求资金允许阿尔弗雷多H-S博士。昂省 伊利诺伊大学土木工程系， Masanobu Shinozuka博士，土木工程和运营部门 研究，普林斯顿大学，继续与博士孝南赵， 韩国汉阳大学土木工程系 韩国土木工程系Chung-Bang Yun博士 高级科学技术研究所，为期24年 个月，一项基于可靠性的合作研究计划 修复土木结构以抵御自然灾害。 这些 研究人员将开发钢的定量损伤模型， 钢筋混凝土结构，并使用它们来评估的程度 现有土木结构的损坏和/或恶化。 他们还 将开发无损检测和基于知识的专家系统 进行实地实验 这些活动的结果将是 用于制定评估桥梁可靠性的策略， 其他结构。 然后，评级可用于推荐 更换或修复。 随着土木结构接近其原始设计寿命， 必须评估损坏和/或恶化的程度， 确定是否需要修复或更换。 这 评估还可用于（1）确定其可靠性， 承受极端负荷，如交通繁忙和自然灾害 (high风和地震）和（2）达成决定的程度 是否需要更换或更换。 的问题 本项目所解决的问题是常见的问题，其解决方案是 对美国和韩国有利。 该项目与 美国的目标-韩国合作科学计划， 寻求提高美国和韩国之间的合作水平， 科学家和工程师通过科学交流， 信息，想法，技能和技术，并通过合作， 互利的问题。

This proposal requests funds to permit Dr. Alfredo H-S. Ang, Department of Civil Engineering, University of Illinois, and Dr. Masanobu Shinozuka, Department of Civil Engineering and Operations Research, Princeton University, to pursue with Dr. Hyo-Nam Cho, Department of Civil Engineering, Hanyang University and Korea Military Academy, and Dr. Chung-Bang Yun, Department of Civil Engineering, Korea Advanced Institute of Science and Technology, for a period of 24 months, a program of cooperative research on reliability-based rehabilitation of civil structures against natural hazards. These researchers will develop quantitative damage models for steel and reinforced concrete structures and use them to assess the degree of damage and/or deterioration of existing civil structures. They also will develop nondestructive tests and knowledge-based expert systems for field experimentation. The results of these activities will be used to develop a strategy for rating the reliability of bridges and other structures. The ratings then may be used to recommend replacement or rehabilitation. As civil structures approach their original intended design life, the degree of damage and/or deterioration must be assessed in order to determine if they need to be rehabilitated or replaced. This assessment also can be used to (1) determine their reliability when subjected to extreme loads such as heavy traffic and natural hazards (high winds and earthquakes) and (2) reach decisions on the degree of rehabilitation or whether replacement is required. The problems addressed by this project are common ones whose solution would be beneficial to the United States and Korea. This project is relevant to the objectives of the U.S.-Korea Cooperative Science Program which seeks to increase the level of cooperation between U.S. and Korean scientists and engineers through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit.
