Computer Aided Evaluation of Bridge Safety

研究人员开发了复杂的基于可靠性的桥梁评级程序，以应对基础设施状况的严重性。这项研究的目的是开发一种计算机工具，将这种桥梁评级技术传递给执业工程师，并就如何使用这种技术提供指导。计算机评估程序包将(1)帮助工程师对桥梁建模做出合理的判断，(2)执行各种评级分析，(3)通过评级过程提供指导，以及(4)在微型计算机应用程序用户界面中解释标准结果。分析程序的范围从简单的标准AASHTO程序到全系统非弹性极限状态分析。将使用竞赛敏感的超文本系统在整个评分过程中培训和指导工程师。考虑到大多数公路部门有限的计算设施，该系统的影响可能是巨大的。这将是一种有效而合理的工具，可以用来评估国家桥梁的安全性。

Researchers have developed sophisticated reliability-based bridge rating procedures to combat the severity of infrastructure condition. the objective of this study is to develop a computer tool to transfer this bridge rating technology to practicing engineers and to provide guidance on how to use this technology. the computer-sided evaluation package would (1) aid the engineer in making sound judgement for bridge modeling, (2) perform the various rating analyses, (3) provide guidance through the rating process, and (4) interpret the results of standard in microcomputer application user-interfaces. The analysis routines will range from the simple standard AASHTO procedures to a full-system inelastic limit state analysis. A contest-sensitive hypertext system will be used to train and guide the engineer throughout the rating process. The impact of the system could be enormous given the limited computational facilities of most highway departments. It would be an efficient and rational tool to use to evaluate the safety of the nation's bridges.
