9402224 Foutch, Douglas A. The main objective of this research is to provide experimental data and analytical results that will significantly improve current practice of evaluation, rehabilitation and design of railway bridges. The program will involve a cooperative effort among researchers from the Association of American Railroads and the University of Illinois. Field tests will be conducted to determine the loading spectra that railway bridges under current operating conditions. Analytical studies will compare measured and calculated member strains. New models for evaluating the remaining life of existing riveted steel bridges will be developed. These are essential for the sound management of the existing bridge stock and will assist the railroads in making important decisions regarding the investment of capital funds. The research results will help to improve the competitiveness of American railroads. ***

9402224 Foutch, Douglas A。这项研究的主要目的是提供实验数据和分析结果，以显着改进铁路桥梁评估、修复和设计的当前实践。 该计划将涉及美国铁路协会和伊利诺伊大学研究人员的合作。 将进行现场测试以确定铁路桥梁在当前运行条件下的载荷谱。 分析研究将比较测量的和计算的成员应变。 将开发评估现有铆接钢桥剩余寿命的新模型。 这些对于现有桥梁库存的健全管理至关重要，并将协助铁路部门做出有关资本资金投资的重要决策。 研究成果将有助于提高美国铁路的竞争力。 ***
