摘要

Abstract: As the population of the nations steel highway structures grow older each year, problems associated with structural details are discovered and must be addressed. Some details are fatigue sensitive and others carry load in a manner not originally intended by the designers. To solve or prevent these problems, it is necessary to understand the magnitude and nature of the stress flow at the problem area. With this information we can develop details that are less sensitive to fatigue, and design them to carry the appropriate loads. In Michigan, several methods are being used to measure strain and analyze stress in highway structures. A few of the technologies used are; electrical resistance strain gages, vibrating wire sensors, and photoelastic coatings. This paper discusses Michigan's experience with these technologies in two applications where they have been useful in analyzing Michigan's link plate details. !5
