This proposal requests funds to permit Dr. Mihran S. Agbabian, Dr. Sami F. Masri, and Dr. James C. Anderson, Department of Civil Engineering, University of Southern California, to pursue with Dr. Seng-Lip Lee, Dr. Somsak Swaddiwudhipong, Dr. Ser-Tong Quek, Dr. Chi Young Liaw, and Dr. Thambirajah Balendra, Department of Civil Engineering, National University of Singapore, for a period of 24 months, a program of cooperative experimental and analytical research on nonlinear structural systems under earthquake loads. The following three research topics will be studied: ductility demand for short period steel frames; behavior of steel frames subjected to earthquake motions in both vertical and horizontal directions; and beam-column moment connections for severe earthquakes. The main goals of this project are to evaluate the need to include stiffer plates in box columns at the connection to beams, to evaluate the ability of current element codes to predict the nonlinear behavior occurring at the joint under limit loads, and to accurately predict the capacity of building structures to resist damaging earthquake motions without failure or collapse. The research will add an international cooperative dimension to ongoing research at the University of Southern California (USC) supported by the National Science Foundation under Grant No. ECE8617623. The proposed cooperative research should provide valuable data to the earthquake engineering profession on structural response to severe earthquake shaking. This cooperative project will make available to the USC team a large scale test facility on which full-size building components can be tested rather than half-scale, as at USC. Comparison of results obtained at the two facilities would provide valuable information on scaling effects in such tests. This project is relevant to the objectives of the Science in Developing Countries Program which seeks to increase the level of cooperation between U.S. scientists and engineers and their counterparts in developing countries through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit. Both groups of collaborators are highly respected scientists who have productive publication records in the field of the proposal.

该提案要求提供资金，以允许米洛斯博士。阿格巴比安， Sami F.博士Masri和James C.安德森，民政部 工程，南加州大学，追求与 Dr. Seng-Lip Lee，Dr. Somsak Swaddiwudhipong，Dr. Ser-Tong Quek， Chi Young Liaw博士和Thambirajah Balendra博士， 新加坡国立大学土木工程专业，一段时间 为期24个月的合作实验和分析计划 地震作用下非线性结构体系的研究。 将研究以下三个研究课题：延性 短周期钢框架的需求;钢框架的性能 在垂直和水平方向都受到地震的影响 方向;和梁柱弯矩连接严重 地震 该项目的主要目标是评估 需要在箱形柱的连接处包括更硬的板， 梁，以评估当前单元代码预测的能力， 在极限载荷下接头处发生的非线性行为， 并准确预测建筑结构的承载能力， 抵抗破坏性的地震运动而不发生故障或倒塌。 这项研究将增加一个国际合作的层面， 南加州大学正在进行的一项研究 由美国国家科学基金会资助， ECE 8617623。 拟议的合作研究应提供 对地震工程专业有价值的数据 结构对强烈地震震动的反应。 这种合作 该项目将为南加州大学团队提供大规模测试 可以测试全尺寸建筑构件的设施 而不是像南加州大学那样的半规模。 所得结果的比较 在这两个设施将提供有价值的信息缩放 在这样的测试中。 该项目与以下目标有关： 发展中国家科学计划，该计划旨在 提高美国科学家与 工程师和发展中国家的同行， 交流科学信息、思想、技能， 技术，并通过在共同问题上的合作， 效益 这两组合作者都受到高度尊重 科学家谁拥有生产出版记录在该领域的 这个提议
